Description
hop-count
Number of hops in a region that the BPDU message passes before
being dropped. The range is 1 to 40 hops.
Defaults
The default is 20 hops.
Command
Mode
Global configuration mode.
Usage Guide
In the region, the BPDU message sent by the root bridge includes a Hot Count field. When the BPDU
message passes a device, the Hop Count is decreased by 1 until it reaches 0, which indicates the
BPDU message times out. The device will drop the BPDU message whose Hop Count is 0.
Changing the max-hops command affects all instances.
Configuration
Examples
This example sets the max-hops of the spanning tree to 10 for all instances.
