C OMMAND U SAGE
This command limits the maximum transmission rate for BPDUs.
E XAMPLE
Console(config)#spanning-tree transmission-limit 4
Console(config)#
max-hops This command configures the maximum number of hops in the region
before a BPDU is discarded. Use the no form to restore the default.
S YNTAX
max-hops hop-number
hop-number - Maximum hop number for multiple spanning tree.
(Range: 1-40)
D EFAULT S ETTING

C OMMAND M ODE
MST Configuration
C OMMAND U SAGE
An MSTI region is treated as a single node by the STP and RSTP protocols.
Therefore, the message age for BPDUs inside an MSTI region is never
changed. However, each spanning tree instance within a region, and the
internal spanning tree (IST) that connects these instances use a hop count
to specify the maximum number of bridges that will propagate a BPDU.
Each bridge decrements the hop count by one before passing on the BPDU.
When the hop count reaches zero, the message is dropped.
