MP1204-XT.
Item Configuration | Spanning Tree | Bridge Settings
Basic Settings
Protocol Version
The MSTP / RSTP / 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 transit Root and Designated Ports to Forwarding
(used in STP compatible mode). Valid values are in the range 4 to 30 seconds.
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
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 to. 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 is delayed. Valid values are in the range 1 to 10
BPDU's per second.
Advanced Settings
Edge Port BPDU
Filtering
Controls whether a port explicitly configured as
Edge
transmits and receives BPDUs.
