Using the Port Configuration on a Set/Clear Command−Based

IOS

The show port command can be used on a Set/Clear command−based IOS switch to view the port configuration. Let’s take a look at the command, its optional syntaxes, and an example of its output:

show port [module/port] show port [module]

Catalyst5002> (enable) show port 2/1

Port	Name		Status	Vlan Level		Duplex Speed		Type
————	———————— ———————— ———— —————— —————— —————— ——————

Using the show port Command on a CLI−Based IOS

The show port command can be used on a CLI−based IOS switch to view the port configuration. Let’s take a look at the command, its syntaxes, and an example of its output:

1912EN#show port ?

block Forwarding of unknown unicast/multicast addresses monitor Port monitoring

system System port configuration

1912EN#show port block ?

multicast Forwarding of unregisterd multicast addresses unicast Forwarding of unknown unicast addresses

1912EN#show port block multicast

Ports receiving unregistered multicast addresses: Ethernet 0/1, Ethernet 0/2, Ethernet 0/3, Ethernet 0/4 Ethernet 0/5, Ethernet 0/6, Ethernet 0/7, Ethernet 0/8 Ethernet 0/9, Ethernet 0/10, Ethernet 0/11, Ethernet 0/12 Ethernet 0/25, FastEthernet 0/26, FastEthernet 0/27

1912EN#show port block unicast

Ports receiving unmatched unicast addresses:

Ethernet 0/1, Ethernet 0/2, Ethernet 0/3, Ethernet 0/4 Ethernet 0/5, Ethernet 0/6, Ethernet 0/7, Ethernet 0/8
