Cisco Systems RJ-45-to-AUX Using the Port Configuration on a Set/Clear CommandBased, Using the show port Command on a CLIBased IOS

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]

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
