Caution You must use the console port for the SLIP connection. When the SLIP connection is enabled and SLIP is attached on the console port, an EIA/TIA-232 terminal cannot connect through the console port. If you are connected to the switch CLI through the console port and you enter the slip attach command, you will lose the console port connection. Use Telnet to access the switch, enter privileged mode, and enter the slip detach command to restore the console port connection. To enable and attach SLIP on the console port, perform this task: Step 1 Step 2 Step 3 Step 4 Step 5 Task Access the switch from a remote host with Telnet. Enter privileged mode on the switch. Set the console port SLIP address and the destination address of the attached host. Verify the SLIP interface configuration. Enable SLIP for the console port. Command telnet {host_name | ip_addr} enable set interface sl0 slip_addr dest_addr show interface slip attach Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 3-8 78-15486-01
