IEEE 802.1D Spanning Tree Protocol (STP)
12
When the spanning-tree protect re-enable is issued to re-enable a port, the following Syslog
messages are generated.
Sep 9 18:43:21:I:STP: BPDU Guard re-enabled on ports ethe 1/4
Sep 9 18:43:23:I:System: Interface ethernet 1/4, state up
Checking for traps
The following SNMP traps are generated for BPDU Guard. Refer to the Unified IP MIB Reference for
details:
• snTrapStpBPDUGuardDetect is generated when a port is disabled because spanning-tree
protect do-disable on a port and that port received a BPDU and disabled the port.
• snTrapSTPBPDUGuardExpire is generated when a port that has been disabled due to a BPDU
Guard violation is re-enabled using the spanning-tree protect re-enable command.
Displaying STP information
You can display the following STP information:
• All the global and interface STP settings
• Detailed STP information for each interface
• STP state information for a VLAN
• STP state information for an individual interface
Displaying STP information for an entire device
To display STP information, enter the following command at any level of the CLI.
Brocade# show spanning-tree vlan 10
VLAN 10 - STP instance 1
