Configuring the SLIP (sl0) Interface on the Console Port
Use the SLIP (sl0) interface for point-to-point SLIP connections between the switch and an IP host.
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:
Task
Step 1
Access the switch from a remote host with Telnet. telnet {host_name | ip_addr}
Step 2
Enter privileged mode on the switch.
Step 3
Set the console port SLIP address and the
destination address of the attached host.
Step 4
Verify the SLIP interface configuration.
Step 5
Enable SLIP for the console port.
To disable SLIP on the console port, perform this task:
Task
Step 1
Access the switch from a remote host with Telnet. telnet {host_name | ip_addr}
Step 2
Enter privileged mode on the switch.
Step 3
Disable SLIP for the console port.
