spanning-tree max-age
Configure the port BPDU aging time. The timer aging reset is updated upon receipt of a BPDU,
when participating in a spanning tree. When a port (root port and port blocking) timer reaches max-
age due to no BPDU message being received, the switch will recalculate the topology.
spanning-tree max-age [6-40s]
20s
Global configuration mode
Sets the BPDU timeout time of the switch in global mode.
Set the BPDU timeout of the switch to 30 seconds:
ECS2020-10P(config)# spanning-tree max-age 30
spanning-tree max-hops
The maximum BPDU hops of a switch-port, BPDU, is reduced by 1 per passing device. If the
switch receives a hops value of 0, the BPDU message will be discarded, and the switch will control
the spanning tree size by that value.
