Ethernet Bridge, STP/RSTP STP/RSTP and Provider Bridge Configuration
Table 19: STP Bridge Level Parameters
Enables or disables STP/RSTP BPDUs transportation
Enabled - STP/RSTP (according to the selected Protocol Type parameter) is set on a
bridge level (enabled on all ports).
Disabled - STP/RSTP is not enabled on any of the ports. If required it is enabled on a
port level.
Determines which protocol is operational when it is enabled:
STP - Spanning Tree Protocol (usually used for Legacy networks)
RSTP - Rapid Spanning Tree Protocol (usually faster than STP)
NOTE: The same protocol is to be used on all relevant network elements.
Maximum time for keeping the received protocol information recorded for a port
before discarding it.
Select the maximum age (6 to 40 seconds).
Determines how often the switch broadcasts its hello message to other switches.
Select the Hello Time (1 to 10 seconds)
Defines the timeout to be spent by a port in the learning and listening states. It is
the value of the forward delay parameter of the bridge.
The bridge with the highest priority is the Root bridge: The higher the Bridge's
priority value, the lower its priority.
Select the Bridge priority (0 to 61440 in steps of 4096)
Select the address according to the bridge designation:
For systems designated as SP-Bridge provider - set the MAC to 0x0180C2000008
For systems designated as CE-Bridge - set the MAC to 0x0180C2000000
The bridge will communicate on the defined MAC and will not accept another
MAC, even if L2CP application is configured on the Ingress port to accept (as
PEER) the RSRV MAC.
STP/RSTP Ports Configuration
To Configure STP/RSTP parameters on a port level
1. In the Network Element tree, open Ethernet Bridge, STP Ports. The STP Ports
(802.1w or 802.1d for RSTP or STP accordingly) pane opens.
2. On the table, select an STP port.
