In this case, all the packets, including the first packets are switched in hardware. Line-rate performance is achieved in this case. All subsequent packets are switched in hardware. The Catalyst 6000 family switch can function as a VMPS server. IEEE 802.1Q Tunneling allows multiple VLANs in other VTP domains to be carried by a single VLAN on the Catalyst 6000 family switch without losing their unique VLAN IDs.
Statistics Use the clear qos statistics command to clear QoS statistic counters.
The clear counters command clears MAC and port counters. IOS ACLs that are mapped to a primary VLAN will get mapped to the associated secondary VLANs. IOS ACLs cannot be mapped to secondary VLANs. QoS ACLs can be mapped to secondary VLANs or primary VLANs. The secure shell encryption feature provides security for Telnet sessions to the switch.
