3.9.45.2 (config-stp-aggr)# spanning-tree
Syntax:
(config-stp-aggr)# spanning-tree
Explanation:
Enable Spanning Tree under aggregation mode.
Negation:
(config-stp-aggr)# no spanning-tree
Show:
# show spanning-tree
3.9.45.3 (config-stp-aggr)# spanning-tree auto-edge
Syntax:
(config-stp-aggr)# spanning-tree auto-edge
Explanation:
Enable auto edge function. When enabled, a port is automatically determined to be at the edge of the
network when it receives no BPDUs.
Negation:
(config-stp-aggr)# no spanning-tree auto-edge
Show:
# show spanning-tree
3.9.45.4 (config-stp-aggr)# spanning-tree bpdu-guard
Syntax:
(config-stp-aggr)# spanning-tree bpdu-guard
Explanation:
Enable BPDU guard function. This feature protects ports from receiving BPDUs. It can prevent loops by
shutting down a port when a BPDU is received instead of putting it into the spanning tree discarding state. If enabled,
the port will disable itself upon receiving valid BPDU's.
Negation:
(config-stp-aggr)# no spanning-tree bpdu-guard
Show:
# show spanning-tree
3.9.45.5 (config-stp-aggr)# spanning-tree edge
Syntax:
(config-stp-aggr)# spanning-tree edge
Explanation:
If an interface is attached to end nodes, you can set it to “Edge”.
Negation:
(config-stp-aggr)# no spanning-tree edge
Show:
# show spanning-tree
