4000 Series Set-Based Switch

4000 Series Set-Based Switch
To set the IP address information on a 4000 series switch, configure the supervisor engine that
is plugged into slot 1 of every switch. This is called the in-band logical interface. Use the command
set interface sc0:
Terry_4000> (enable) set interface sc0 172.16.10.17 255.255.255.0
Interface sc0 IP address and netmask set.
By default, the switch is configured for VLAN 1, which can be seen by using the show interface
command. Notice also that the broadcast address for the subnet shows up and that you can change
it by entering it with the set interface sc0 command (but we can think of only one reason that
you would want to change it—to mess with the people in your MIS department):
Terry_4000> (enable) show interface
sl0: flags=51<UP,POINTOPOINT,RUNNING>
slip 0.0.0.0 dest 0.0.0.0
sc0: flags=63<UP,BROADCAST,RUNNING>
vlan 1 inet 172.16.10.17 netmask 255.255.255.0 broadcast 172.16.10.255
Terry_4000> (enable)
Connecting and Logging In to a Switch 431
The command set interface sl0 ip_address mask would be used for modem access to
the switch. This enables addressing on the Serial Line Internet Protocol (SLIP) process. Before
accessing the switch via a modem, the modem process must be enabled on the switch by using the
set system modem enable command. The modem operates at a speed of 9600bps by default.
