Description
The STP protocol version setting. Selections are STP,
Controls the bridge priority. Lower numeric values have higher priority. The
bridge priority plus the MSTI instance number, concatenated with the 6-byte
MAC address of the switch forms a Bridge Identifier.
For MSTP operation, this is the priority of the CIST. Otherwise, this is the
priority of the STP/RSTP bridge.
The delay used by STP bridges to transition root and designated ports to
forwarding (used in STP compatible mode). Valid values are in the range of
4 to 30 seconds
Default: 15
Minimum: The higher of
Maximum: 30
The maximum age of the information transmitted by the Bridge when it is the
Root Bridge. Valid values are in the range 6 to 40 seconds.
Default: 20
Minimum: The higher of
Maximum: The lower of
This defines the initial value of remaining hops for MSTI information
generated at the boundary of an MSTI region. It defines how many bridges a
root bridge can distribute its BPDU information. Valid values are in the range
6 to 40 hops.
The number of BPDU's a bridge port can send per second. When exceeded,
transmission of the next BPDU is delayed. Valid values are in the range of
to 10 BPDU's per second.
