5 - Max Hops
MSTP regions use this parameter to discard BPDUs. The Max Hop
counter in a BPDU is decremented every time the BPDU crosses an
MSTP region boundary. Once the counter reaches zero, the BPDU
is deleted. The range is 1 to 40 hops. The default is 20.
6 - Configuration Name
The name of the MSTP region. The range is 0 (zero) to 32
alphanumeric characters in length. The name, which is case-
sensitive, must be the same on all bridges in a region. Examples
include Sales Region and Production Region.
7 - Revision Level
The revision level of an MSTP region. The range is 0 (zero) to 255.
This is an arbitrary number that you assign to a region. The
revision level must be the same on all bridges in a region.
Different regions can have the same revision level without
conflict.
8 - Bridge Identifier
The MAC address of the bridge. The bridge identifier is used as a
tie breaker in the selection of a root bridge when two or more
bridges have the same bridge priority value. This value cannot be
changed.
