Configuring the Catalyst 1900 Switch
The switch output below shows the configuration of a Fast Ethernet port
on the 1900 switch. Notice that the command is interface fastethernet,
but the slot is still 0. The only ports available are 26 and 27.
Todd1900EN(config)#int fastEthernet ?
<0-0> FastEthernet IEEE 802.3
Todd1900EN(config)#int fastEthernet 0/?
<26-27> FastEthernet IEEE 802.3
Todd1900EN(config)#int fastEthernet 0/26
Todd1900EN(config-if)#int fast 0/27
Todd1900EN(config-if)#[Ctrl+Z]
After you make any changes you want to the interfaces, you can view the
different interfaces with the show interface command.
The following switch output shows the command used to view a 10BaseT
interface and the command to view a Fast Ethernet interface.
Todd1900EN#sh int e0/1
Ethernet 0/1 is Suspended-no-linkbeat
Hardware is Built-in 10Base-T
Address is 0030.80CC.7D01
MTU 1500 bytes, BW 10000 Kbits
802.1d STP State: Forwarding Forward Transitions: 1
[output cut]
Todd1900EN#sh int f0/26
FastEthernet 0/26 is Suspended-no-linkbeat
Hardware is Built-in 100Base-TX
Address is 0030.80CC.7D1A
MTU 1500 bytes, BW 100000 Kbits
802.1d STP State: Blocking Forward Transitions: 0
[output cut]
Configuring Interface Descriptions
You can administratively set a name for each interface on the 1900 switch.
Like the hostname, the descriptions are only locally significant.
For the 1900 series switch, use the description command. You cannot
use spaces with the description command, but you can use underscores if
you need to.
