DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode. Enter your password if
prompted.
enable
Example:
Switch> enable
Step 1
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 2
Specifies the number of hops in a region before the BPDU is
discarded, and the information held for a port is aged.
spanning-tree mst max-hops hop-count
Example:
Switch(config)# spanning-tree mst max-hops
25
Step 3
For hop-count, the range is 1 to 255; the default is 20.
Returns to privileged EXEC mode.end
Example:
Switch(config)# end

Specifying the Link Type to Ensure Rapid Transitions
If you connect a port to another port through a point-to-point link and the local port becomes a designated
port, the RSTP negotiates a rapid transition with the other port by using the proposal-agreement handshake
to ensure a loop-free topology.
By default, the link type is controlled from the duplex mode of the interface: a full-duplex port is considered
to have a point-to-point connection; a half-duplex port is considered to have a shared connection. If you have
a half-duplex link physically connected point-to-point to a single port on a remote switch running MSTP, you
can override the default setting of the link type and enable rapid transitions to the forwarding state.
This procedure is optional.
Before You Begin
A multiple spanning tree (MST) must be specified and enabled on the switch. For instructions, see Related
Topics.
