IEEE 802.1D Spanning Tree Protocol (STP)
BigIron RX# show spanning-tree detail vlan 10
VLAN 10 - STP instance 1
--------------------------------------------------------------------
STP Bridge Parameters:
Bridge identifier - 0x8000000480a04000
Root bridge - 0x8000000480a04000
Control ports - ethe 1/3 ethe 1/13
Active global timers - None
STP Port Parameters:
Port 1/3 - DISABLED
Port 1/13 - DISABLED
VLAN 20 - STP instance 2
--------------------------------------------------------------------
STP Bridge Parameters:
Bridge identifier - 0x8000000480a04000
Root bridge - 0x8000000480a04000
Control ports - ethe 1/3 ethe 1/13
Active global timers - None
STP Port Parameters:
Port 1/3 - DISABLED
Port 1/13 - DISABLED
If a port is disabled, the only information shown by this command is "DISABLED". If a port is
enabled, this display shows the following information.
Syntax: show spanning-tree detail [vlan <vlan-id> [ethernet <slot/port>]]
The vlan <vlan-id> parameter specifies a VLAN.
The ethernet <slot>/<portnum> parameter specifies an individual port within the VLAN (if
specified).
The <num> parameter specifies the number of VLANs you want the CLI to skip before displaying
detailed STP information. For example, if the device has six VLANs configured (VLAN IDs 1, 2, 3, 99,
128, and 256) and you enter the command show span detail 4, detailed STP information is
displayed for VLANs 128 and 256 only.
NOTE
If the configuration includes VLAN groups, the show span detail command displays the master
VLANs of each group but not the member VLANs within the groups. However, the command does
indicate that the VLAN is a master VLAN. The show span detail vlan <vlan-id> command displays
the information for the VLAN even if it is a member VLAN. To list all the member VLANs within a VLAN
group, enter the show vlan-group [<group-id>] command.
The show spanning-tree detail command shows the following information for each VLAN
participating in the spanning tree.
