Description

Protocol Version

The STP protocol version setting. Valid values are STP, RSTP and
MSTP.

Bridge Priority

Controls the bridge priority. Lower numeric values have better
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.

Forward Delay

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 4 to 30 seconds

-Default:

15

-Minimum:

The higher of 4 or [(Max. Message Age / 2) + 1]

-Maximum:

30

Max Age

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 6 or [2 x (Hello Time + 1)].

-Maximum:

The lower of 40 or [2 x (Forward Delay -1)]

Maximum Hop

Count

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.

Transmit Hold
Count

The number of BPDU's a bridge port can send per second. When
exceeded, transmission of the next BPDU will be delayed. Valid
values are in the range 1 to 10 BPDU's per second.

Edge Port BPDU
Filtering

Control whether a port explicitly configured as Edge will transmit
and receive BPDUs.

Edge Port BPDU
Guard

Control whether a port explicitly configured as Edge will disable
itself upon reception of a BPDU. The port will enter the
