Chapter 8. Configuring physical switches for OpenStack Networking This chapter documents the common physical switch configuration steps required for OpenStack Networking. Vendor-specific configuration is included for the following switches: Cisco Catalyst Cisco Nexus Cumulus Linux Extreme Networks EXOS Juniper EX Series 8.1. Planning your physical network environment The physical network adapters in your OpenStack nodes carry different types of network traffic, such as instance traffic, storage data, or authentication requests. The type of traffic these NICs carry affects how you must configure the ports on the physical switch. First, you must decide which physical NICs on your Compute node you want to carry which types of traffic. Then, when the NIC is cabled to a physical switch port, you must configure the switch port to allow trunked or general traffic. For example, the following diagram depicts a Compute node with two NICs, eth0 and eth1. Each NIC is cabled to a Gigabit Ethernet port on a physical switch, with eth0 carrying instance traffic, and eth1 providing connectivity for OpenStack services: Sample network layout Note This diagram does not include any additional redundant NICs required for fault tolerance. For information on network interface bonds, see the Network Interface Bonding chapter of the Advanced Overcloud Customization guide. 8.2. Configuring a Cisco Catalyst switch 8.2.1. About trunk ports With OpenStack Networking you can connect instances to the VLANs that already exist on your physical network. The term trunk is used to describe a port that allows multiple VLANs to traverse through the same port. Using these ports, VLANs can span across multiple switches, including virtual switches. For example, traffic tagged as VLAN110 in the physical network reaches the Compute node, where the 8021q module directs the tagged traffic to the appropriate VLAN on the vSwitch. 8.2.2. Configuring trunk ports for a Cisco Catalyst switch If using a Cisco Catalyst switch running Cisco IOS, you might use the following configuration syntax to allow traffic for VLANs 110 and 111 to pass through to your instances. This configuration assumes that your physical node has an ethernet cable connected to interface GigabitEthernet1/0/12 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. Use the following list to understand these parameters: Field Description interface GigabitEthernet1/0/12 The switch port that the NIC of the X node connects to. Ensure that you replace the GigabitEthernet1/0/12 value with the correct port value for your environment. Use the show interface command to view a list of ports. description Trunk to Compute Node A unique and descriptive value that you can use to identify this interface. spanning-tree portfast trunk If your environment uses STP, set this value to instruct Port Fast that this port is used to trunk traffic. switchport trunk encapsulation dot1q Enables the 802.1q trunking standard (rather than ISL). This value varies depending on the configuration that your switch supports. switchport mode trunk Configures this port as a trunk port, rather than an access port, meaning that it allows VLAN traffic to pass through to the virtual switches. switchport trunk native vlan 2 Set a native VLAN to instruct the switch where to send untagged (non-VLAN) traffic. switchport trunk allowed vlan 2,110,111 Defines which VLANs are allowed through the trunk. 8.2.3. About access ports Not all NICs on your Compute node carry instance traffic, and so you do not need to configure all NICs to allow multiple VLANs to pass through. Access ports require only one VLAN, and might fulfill other operational requirements, such as transporting management traffic or Block Storage data. These ports are commonly known as access ports and usually require a simpler configuration than trunk ports. 8.2.4. Configuring access ports for a Cisco Catalyst switch Using the example from the Sample network layout diagram, GigabitEthernet1/0/13 (on a Cisco Catalyst switch) is configured as an access port for eth1 . In this configuration,your physical node has an ethernet cable connected to interface GigabitEthernet1/0/12 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. These settings are described below: Field Description interface GigabitEthernet1/0/13 The switch port that the NIC of the X node connects to. Ensure that you replace the GigabitEthernet1/0/12 value with the correct port value for your environment. Use the show interface command to view a list of ports. description Access port for Compute Node A unique and descriptive value that you can use to identify this interface. switchport mode access Configures this port as an access port, rather than a trunk port. switchport access vlan 200 Configures the port to allow traffic on VLAN 200. You must configure your Compute node with an IP address from this VLAN. spanning-tree portfast If using STP, set this value to instruct STP not to attempt to initialize this as a trunk, allowing for quicker port handshakes during initial connections (such as server reboot). 8.2.5. About LACP port aggregation You can use LACP to bundle multiple physical NICs together to form a single logical channel. Also known as 802.3ad (or bonding mode 4 in Linux), LACP creates a dynamic bond for load-balancing and fault tolerance. You must configure LACP at both physical ends: on the physical NICs, and on the physical switch ports. 8.2.6. Configuring LACP on the physical NIC Edit the /home/stack/network-environment.yaml file: Configure the Open vSwitch bridge to use LACP: For information on configuring network bonds, see the Network Interface Bonding chapter of the Advanced Overcloud Customization guide. 8.2.7. Configuring LACP for a Cisco Catalyst switch In this example, the Compute node has two NICs using VLAN 100: Physically connect both NICs on the Compute node to the switch (for example, ports 12 and 13). Create the LACP port channel: Configure switch ports 12 (Gi1/0/12) and 13 (Gi1/0/13): Review your new port channel. The resulting output lists the new port-channel Po1 , with member ports Gi1/0/12 and Gi1/0/13 : Note Remember to apply your changes by copying the running-config to the startup-config: copy running-config startup-config . 8.2.8. About MTU settings You must adjust your MTU size for certain types of network traffic. For example, jumbo frames (9000 bytes) are required for certain NFS or iSCSI traffic. Note You must change MTU settings from end-to-end on all hops that the traffic is expected to pass through, including any virtual switches. For information on changing the MTU in your OpenStack environment, see Chapter 9, Configure maximum transmission unit (MTU) settings . 8.2.9. Configuring MTU settings for a Cisco Catalyst switch Complete the steps in this example procedure to enable jumbo frames on your Cisco Catalyst 3750 switch. Review the current MTU settings: MTU settings are changed switch-wide on 3750 switches, and not for individual interfaces. Run the following commands to configure the switch to use jumbo frames of 9000 bytes. You might prefer to configure the MTU settings for individual interfaces, if your switch supports this feature. Note Remember to save your changes by copying the running-config to the startup-config: copy running-config startup-config . Reload the switch to apply the change. Important Reloading the switch causes a network outage for any devices that are dependent on the switch. Therefore, reload the switch only during a scheduled maintenance period. After the switch reloads, confirm the new jumbo MTU size. The exact output may differ depending on your switch model. For example, System MTU might apply to non-Gigabit interfaces, and Jumbo MTU might describe all Gigabit interfaces. 8.2.10. About LLDP discovery The ironic-python-agent service listens for LLDP packets from connected switches. The collected information can include the switch name, port details, and available VLANs. Similar to Cisco Discovery Protocol (CDP), LLDP assists with the discovery of physical hardware during the director introspection process. 8.2.11. Configuring LLDP for a Cisco Catalyst switch Run the lldp run command to enable LLDP globally on your Cisco Catalyst switch: View any neighboring LLDP-compatible devices: Note Remember to save your changes by copying the running-config to the startup-config: copy running-config startup-config . 8.3. Configuring a Cisco Nexus switch 8.3.1. About trunk ports With OpenStack Networking you can connect instances to the VLANs that already exist on your physical network. The term trunk is used to describe a port that allows multiple VLANs to traverse through the same port. Using these ports, VLANs can span across multiple switches, including virtual switches. For example, traffic tagged as VLAN110 in the physical network reaches the Compute node, where the 8021q module directs the tagged traffic to the appropriate VLAN on the vSwitch. 8.3.2. Configuring trunk ports for a Cisco Nexus switch If using a Cisco Nexus you might use the following configuration syntax to allow traffic for VLANs 110 and 111 to pass through to your instances. This configuration assumes that your physical node has an ethernet cable connected to interface Ethernet1/12 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.3.3. About access ports Not all NICs on your Compute node carry instance traffic, and so you do not need to configure all NICs to allow multiple VLANs to pass through. Access ports require only one VLAN, and might fulfill other operational requirements, such as transporting management traffic or Block Storage data. These ports are commonly known as access ports and usually require a simpler configuration than trunk ports. 8.3.4. Configuring access ports for a Cisco Nexus switch Using the example from the Sample network layout diagram, Ethernet1/13 (on a Cisco Nexus switch) is configured as an access port for eth1 . This configuration assumes that your physical node has an ethernet cable connected to interface Ethernet1/13 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.3.5. About LACP port aggregation You can use LACP to bundle multiple physical NICs together to form a single logical channel. Also known as 802.3ad (or bonding mode 4 in Linux), LACP creates a dynamic bond for load-balancing and fault tolerance. You must configure LACP at both physical ends: on the physical NICs, and on the physical switch ports. 8.3.6. Configuring LACP on the physical NIC Edit the /home/stack/network-environment.yaml file: Configure the Open vSwitch bridge to use LACP: For information on configuring network bonds, see the Network Interface Bonding chapter of the Advanced Overcloud Customization guide. 8.3.7. Configuring LACP for a Cisco Nexus switch In this example, the Compute node has two NICs using VLAN 100: Physically connect the Compute node NICs to the switch (for example, ports 12 and 13). Confirm that LACP is enabled: Configure ports 1/12 and 1/13 as access ports, and as members of a channel group. Depending on your deployment, you can deploy trunk interfaces rather than access interfaces. For example, for Cisco UCI the NICs are virtual interfaces, so you might prefer to configure access ports exclusively. Often these interfaces contain VLAN tagging configurations. 8.3.8. About MTU settings You must adjust your MTU size for certain types of network traffic. For example, jumbo frames (9000 bytes) are required for certain NFS or iSCSI traffic. Note You must change MTU settings from end-to-end on all hops that the traffic is expected to pass through, including any virtual switches. For information on changing the MTU in your OpenStack environment, see Chapter 9, Configure maximum transmission unit (MTU) settings . 8.3.9. Configuring MTU settings for a Cisco Nexus 7000 switch Apply MTU settings to a single interface on 7000-series switches. Run the following commands to configure interface 1/12 to use jumbo frames of 9000 bytes: 8.3.10. About LLDP discovery The ironic-python-agent service listens for LLDP packets from connected switches. The collected information can include the switch name, port details, and available VLANs. Similar to Cisco Discovery Protocol (CDP), LLDP assists with the discovery of physical hardware during the director introspection process. 8.3.11. Configuring LLDP for a Cisco Nexus 7000 switch You can enable LLDP for individual interfaces on Cisco Nexus 7000-series switches: Note Remember to save your changes by copying the running-config to the startup-config: copy running-config startup-config . 8.4. Configuring a Cumulus Linux switch 8.4.1. About trunk ports With OpenStack Networking you can connect instances to the VLANs that already exist on your physical network. The term trunk is used to describe a port that allows multiple VLANs to traverse through the same port. Using these ports, VLANs can span across multiple switches, including virtual switches. For example, traffic tagged as VLAN110 in the physical network reaches the Compute node, where the 8021q module directs the tagged traffic to the appropriate VLAN on the vSwitch. 8.4.2. Configuring trunk ports for a Cumulus Linux switch Use the following configuration syntax to allow traffic for VLANs 100 and 200 to pass through to your instances. This configuration assumes that your physical node has transceivers connected to switch ports swp1 and swp2 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.4.3. About access ports Not all NICs on your Compute node carry instance traffic, and so you do not need to configure all NICs to allow multiple VLANs to pass through. Access ports require only one VLAN, and might fulfill other operational requirements, such as transporting management traffic or Block Storage data. These ports are commonly known as access ports and usually require a simpler configuration than trunk ports. 8.4.4. Configuring access ports for a Cumulus Linux switch Using the example from the Sample network layout diagram, swp1 (on a Cumulus Linux switch) is configured as an access port. This configuration assumes that your physical node has an ethernet cable connected to the interface on the physical switch. Cumulus Linux switches use eth for management interfaces and swp for access/trunk ports. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.4.5. About LACP port aggregation You can use LACP to bundle multiple physical NICs together to form a single logical channel. Also known as 802.3ad (or bonding mode 4 in Linux), LACP creates a dynamic bond for load-balancing and fault tolerance. You must configure LACP at both physical ends: on the physical NICs, and on the physical switch ports. 8.4.6. About MTU settings You must adjust your MTU size for certain types of network traffic. For example, jumbo frames (9000 bytes) are required for certain NFS or iSCSI traffic. Note You must change MTU settings from end-to-end on all hops that the traffic is expected to pass through, including any virtual switches. For information on changing the MTU in your OpenStack environment, see Chapter 9, Configure maximum transmission unit (MTU) settings . 8.4.7. Configuring MTU settings for a Cumulus Linux switch This example enables jumbo frames on your Cumulus Linux switch. Note Remember to apply your changes by reloading the updated configuration: sudo ifreload -a 8.4.8. About LLDP discovery The ironic-python-agent service listens for LLDP packets from connected switches. The collected information can include the switch name, port details, and available VLANs. Similar to Cisco Discovery Protocol (CDP), LLDP assists with the discovery of physical hardware during the director introspection process. 8.4.9. Configuring LLDP for a Cumulus Linux switch By default, the LLDP service lldpd runs as a daemon and starts when the switch boots. To view all LLDP neighbors on all ports/interfaces, run the following command: 8.5. Configuring a Extreme Exos switch 8.5.1. About trunk ports With OpenStack Networking you can connect instances to the VLANs that already exist on your physical network. The term trunk is used to describe a port that allows multiple VLANs to traverse through the same port. Using these ports, VLANs can span across multiple switches, including virtual switches. For example, traffic tagged as VLAN110 in the physical network reaches the Compute node, where the 8021q module directs the tagged traffic to the appropriate VLAN on the vSwitch. 8.5.2. Configuring trunk ports on an Extreme Networks EXOS switch If using an X-670 series switch, refer to the following example to allow traffic for VLANs 110 and 111 to pass through to your instances. This configuration assumes that your physical node has an ethernet cable connected to interface 24 on the physical switch. In this example, DATA and MNGT are the VLAN names. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.5.3. About access ports Not all NICs on your Compute node carry instance traffic, and so you do not need to configure all NICs to allow multiple VLANs to pass through. Access ports require only one VLAN, and might fulfill other operational requirements, such as transporting management traffic or Block Storage data. These ports are commonly known as access ports and usually require a simpler configuration than trunk ports. 8.5.4. Configuring access ports for an Extreme Networks EXOS switch In this configuration example, on a Extreme Networks X-670 series switch, 10 is used as an access port for eth1 . This configuration assumes that your physical node has an ethernet cable connected to interface 10 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. For example: 8.5.5. About LACP port aggregation You can use LACP to bundle multiple physical NICs together to form a single logical channel. Also known as 802.3ad (or bonding mode 4 in Linux), LACP creates a dynamic bond for load-balancing and fault tolerance.

For more information, see https://gtacknowledge.extremenetworks.com/articles/How_To/LACP-configured-ports-interfere-with-PXE-DHCP-on-servers 8.5.8. About MTU settings You must adjust your MTU size for certain types of network traffic. For example, jumbo frames (9000 bytes) are required for certain NFS or iSCSI traffic. Note You must change MTU settings from end-to-end on all hops that the traffic is expected to pass through, including any virtual switches.

Configuring a Juniper EX Series switch 8.6.1. About trunk ports With OpenStack Networking you can connect instances to the VLANs that already exist on your physical network. The term trunk is used to describe a port that allows multiple VLANs to traverse through the same port. Using these ports, VLANs can span across multiple switches, including virtual switches. For example, traffic tagged as VLAN110 in the physical network reaches the Compute node, where the 8021q module directs the tagged traffic to the appropriate VLAN on the vSwitch. 8.6.2. Configuring trunk ports for a Juniper EX Series switch If using a Juniper EX series switch running Juniper JunOS, use the following configuration syntax to allow traffic for VLANs 110 and 111 to pass through to your instances. This configuration assumes that your physical node has an ethernet cable connected to interface ge-1/0/12 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.6.3. About access ports Not all NICs on your Compute node carry instance traffic, and so you do not need to configure all NICs to allow multiple VLANs to pass through. Access ports require only one VLAN, and might fulfill other operational requirements, such as transporting management traffic or Block Storage data. These ports are commonly known as access ports and usually require a simpler configuration than trunk ports. 8.6.4. Configuring access ports for a Juniper EX Series switch This example on, a Juniper EX series switch, shows ge-1/0/13 as an access port for eth1 . This configuration assumes that your physical node has an ethernet cable connected to interface ge-1/0/13 on the physical switch. Important These values are examples. You must change the values in this example to match those in your environment. Copying and pasting these values into your switch configuration without adjustment can result in an unexpected outage. 8.6.5. About LACP port aggregation You can use LACP to bundle multiple physical NICs together to form a single logical channel. Also known as 802.3ad (or bonding mode 4 in Linux), LACP creates a dynamic bond for load-balancing and fault tolerance. You must configure LACP at both physical ends: on the physical NICs, and on the physical switch ports. 8.6.6. Configuring LACP on the physical NIC Edit the /home/stack/network-environment.yaml file: Configure the Open vSwitch bridge to use LACP: For information on configuring network bonds, see the Network Interface Bonding chapter of the Advanced Overcloud Customization guide. 8.6.7. Configuring LACP for a Juniper EX Series switch In this example, the Compute node has two NICs using VLAN 100. Physically connect the Compute node's two NICs to the switch (for example, ports 12 and 13). Create the port aggregate: Configure switch ports 12 (ge-1/0/12) and 13 (ge-1/0/13) to join the port aggregate ae1 : Note For Red Hat OpenStack Platform director deployments, in order to PXE boot from the bond, you must configure one of the bond members as lacp force-up toensure that only one bond member comes up during introspection and first boot. The bond member that you configure with lacp force-up must be the same bond member that has the MAC address in instackenv.json (the MAC address known to ironic must be the same MAC address configured with force-up). Enable LACP on port aggregate ae1 : Add aggregate ae1 to VLAN 100: Review your new port channel. The resulting output lists the new port aggregate ae1 with member ports ge-1/0/12 and ge-1/0/13 : Note Remember to apply your changes by running the commit command. 8.6.8. About MTU settings You must adjust your MTU size for certain types of network traffic. For example, jumbo frames (9000 bytes) are required for certain NFS or iSCSI traffic. Note You must change MTU settings from end-to-end on all hops that the traffic is expected to pass through, including any virtual switches. For information on changing the MTU in your OpenStack environment, see Chapter 9, Configure maximum transmission unit (MTU) settings . 8.6.9. Configuring MTU settings for a Juniper EX Series switch This example enables jumbo frames on your Juniper EX4200 switch. Note The MTU value is calculated differently depending on whether you are using Juniper or Cisco devices. For example, 9216 on Juniper would equal to 9202 for Cisco. The extra bytes are used for L2 headers, where Cisco adds this automatically to the MTU value specified, but the usable MTU will be 14 bytes smaller than specified when using Juniper. So in order to support an MTU of 9000 on the VLANs, the MTU of 9014 would have to be configured on Juniper. For Juniper EX series switches, MTU settings are set for individual interfaces. These commands configure jumbo frames on the ge-1/0/14 and ge-1/0/15 ports: Note Remember to save your changes by running the commit command. If using a LACP aggregate, you will need to set the MTU size there, and not on the member NICs. For example, this setting configures the MTU size for the ae1 aggregate: 8.6.10. About LLDP discovery The ironic-python-agent service listens for LLDP packets from connected switches. The collected information can include the switch name, port details, and available VLANs. Similar to Cisco Discovery Protocol (CDP), LLDP assists with the discovery of physical hardware during the director introspection process. 8.6.11. Configuring LLDP for a Juniper EX Series switch You can enable LLDP globally for all interfaces, or just for individual ones: Use the following too enable LLDP globally on your Juniper EX 4200 switch: Use the following to enable LLDP for the single interface ge-1/0/14 : Note Remember to apply your changes by running the commit command.
