Using Tardis' VLAN switch

We have a very nice 24 port Cisco Catalyst 2900 XL switch donated by User:sjh. It runs Cisco IOS Version 12.0(5.1)XP [c2900XL-h2s-mz-120.5.1-XP.bin]. Cisco have a configuration guide and command reference online.

It runs a telnet server on the admin VLAN at 192.168.1.4 and is connected to Racnoss. Here's a dump of the switchport config:

Current configuration:
!
version 12.0
no service pad

To configure another port connect to the switch via telnet or via Racnoss and do something like:

 Switch>en
 Password:
 Switch#conf t
 Enter configuration commands, one per line.  End with CNTL/Z.
 Switch(config)#int fa0/16
 Switch(config-if)#description HOSTNAME
 Switch(config-if)#switchport access vlan 3
 Switch(config-if)#spanning-tree portfast
 Switch(config-if)#exit
 Switch(config)#exit
 Switch#

Use write memory to save your changes to the flash memory once you are happy with the new configuration.

The old 3com switch is also kicking around.
