2950 and 3550 Switches

2950 and 3550 Switches
These switches take the type slot/port command with either the interface command or the
show command. The interface command enables you to set interface-specific configurations.
As the range of 2950 and 3550 switches increases, it may be that several slots are available. The
following example demonstrates a 2950:
Terry_2950#config t
Enter configuration commands, one per line. End with CNTL/Z
Terry_2950(config)#interface fastEthernet ?
<0-2> FastEthernet interface number
Terry_2950(config)#interface fastEthernet 0/?
<1-24> FastEthernet interface number
Terry_2950(config)#interface fastEthernet 0/1
Terry_2950(config-if)#?
Interface configuration commands:
arp Set arp type (arpa, probe, snap) or timeout
434 Chapter 13  Connecting the Switch Block
bandwidth Set bandwidth informational parameter
carrier-delay Specify delay for interface transitions
cdp CDP interface subcommands
[output cut]
spanning-tree Spanning Tree Subsystem
speed Configure speed operation.
storm-control storm configuration
switchport Set switching mode characteristics
timeout Define timeout values for this interface
To configure the FastEthernet ports, the command is interface fastethernet 0/#:

Terry_2950(config-if)#interface fa 0/2
Terry_2950(config-if)#interface fa0/3
Terry_2950(config-if)#exit
You can view the ports with the show interface command:
Terry_2950#show interface fa0/1
