Displaying STP State Information for an Individual Interface
To display STP state information for an individual port, you can use the methods in "Displaying STP Information
for an Entire Device" on page 12-7 or "Displaying Detailed STP Information for each Interface". You also can
display STP state information for a specific port using either of the following methods.
USING THE CLI
To display information for a specific port, enter a command such as the following at any level of the CLI:
BigIron(config)# show interface ethernet 3/11
FastEthernet3/11 is up, line protocol is up
Hardware is FastEthernet, address is 00e0.52a9.bb49 (bia 00e0.52a9.bb49)
Configured speed auto, actual 100Mbit, configured duplex fdx, actual fdx
Member of L2 VLAN ID 1, port is untagged, port state is FORWARDING
STP configured to ON, priority is level0, flow control enabled
mirror disabled, monitor disabled
Not member of any active trunks
Not member of any configured trunks
No port name
MTU 1500 bytes, encapsulation ethernet
5 minute input rate: 352 bits/sec, 0 packets/sec, 0.00% utilization
5 minute output rate: 0 bits/sec, 0 packets/sec, 0.00% utilization
1238 packets input, 79232 bytes, 0 no buffer
Received 686 broadcasts, 0 runts, 0 giants
0 input errors, 0 CRC, 0 frame, 0 ignored
529 multicast
918 packets output, 63766 bytes, 0 underruns
0 output errors, 0 collisions
The STP information is shown in bold type in this example.
Syntax: show interfaces [ethernet | pos <portnum>] | [loopback <num>] | [slot <slot-num>] | [ve <num>] | [brief]
You also can display the STP states of all ports by entering a command such as the following, which uses the
brief parameter:
12 - 14
Displays...
The current values for the following timers:
• Message age – The number of seconds this port has been
waiting for a hello message from the root bridge.
• Forward delay – The number of seconds that have passed since
the last topology change and consequent reconvergence.
• Hold time – The number of seconds that have elapsed since
transmission of the last Configuration BPDU.
The number of BPDUs sent and received on this port since the
software was reloaded.
