Initial setup of Cisco Catalyst 2490, 2900
Almost all models of this configuration are configured identically.
After entering through the console on the communicator we will see:
Switch>
All main settings are made in the "enable" mode.
Next you need to go to "enable" mode :
Switch> enable
Set the password on the switch. In order to keep all the settings in secret☺. To do this, go to configuration mode:
Switch# configure terminal
Switch (config)# enable password YOUR_PASSWORD
Put the password on telnet:
Switch(config)# line vty 0 15
Switch(config-line)#password YOUR_TELNET_PASSWORD
Allow login via telnet:
Switch(config-line)# login
Switch(config)# exit
Assign host name:
Switch(config)# hostname cisco
Add the network address to the switch (by default, only the first VLAN is set):
cisco(config)# interface vlan 1
cisco(config-if)# ip address 192.168.1.2 255.255.255.0
cisco(config-if)# exit
Add DNS server address:
cisco(config)# ip name-server 192.168.1.111
cisco(config)# exit
Set the time:
cisco# clock set 09:00:50 16 Sep 2012
We will configure interfaces at once, after these settings the switch has to start pinging:
cisco# configure terminal
cisco(config)# interface vlan 1
cisco(config-if-range)# description not_used
cisco(config-if-range)# no shutdown
cisco(config-if-range)# no cdp enable
cisco(config-if-range)# exit
Turn on the web interface, I think it will not hurt:
cisco(config)# ip http server
Set the default gateway:
cisco(config)# ip default-gateway 192.168.1.1
cisco(config)#exit
To view the configuration, use the command:
cisco#show running-config
To save the configuration, use the command:
cisco# copy running-config startup-config
Or:
cisco# wri
At this point, the basic setup is complete.
