If you are using a local network connection to the administrative interface, set sc0. If you are using a SLIP connection to the administrative interface, set sl0. For example, you need to configure static routes if your Telnet station or SNMP network management workstation is on a different network from the switch. See Figure 5-2 for an example. See Figure 5-3 for an example.
None Enable the serial line interface protocol for the console port.
If you are connected to the administrative interface through the serial port and you enter the slip attach command, you will lose the serial connection. In that case, use Telnet to access the administrative interface, enter privileged mode, and type slip detach to restore the console port, or reset the switch. Figure 5-4 shows an example of the show config command output. Press Return after each entry to create a blank line between each entry. This mode gives read and write access to all objects in the MIB, but does not allow access to the community strings.
