Configuring RSTP 4 The RSTP Bridge and Port contains the following information. RSTP Bridge Parameters Vlan The port-based VLAN that owns the STP instance. VLAN 1 is the default VLAN. If you have not configured port-based VLANs on this device, all 802.1W information is for VLAN 1. Priority The preference that STP gives this port relative to other ports for forwarding traffic out of the spanning tree. A higher numerical value means a lower priority. Max.Age The number of seconds this device or VLAN waits for a hello message from the root bridge before deciding the root has become unavailable and performing a reconvergence. Hello Time The interval between each configuration BPDU sent by the root bridge. Forward Delay The number of seconds this device or VLAN waits following a topology change and consequent reconvergence. Forced version The configured force version value. One of the following value is displayed: • 0 - The bridge has been forced to operate in an STP compatibility mode. • 2 - The bridge has been forced to operate in an 802.1W mode. (This is the default.) RSTP Port Parameters Vlan The port-based VLAN that owns the STP instance. VLAN 1 is the default VLAN. If you have not configured port-based VLANs on this device, all 802.1W information is for VLAN 1. Port Admin Edge If set to enabled, then the port becomes an edge port in the domain. Port Admin Pt2pt Mac If set to enabled, then a port is connected to another port through a point-to-point link. The point-to-point link increases the speed of convergence. This parameter, however, does not auto-detect whether or not the link is a physical point-to-point link. Force Migration Check The force-migration-check parameter forces the specified port to sent one RST BPDU. If only STP BPDUs are received in response to the sent RST BPDU, then the port will go return to sending STP BPDUs. Priority This specifies the priority of the bridge. You can enter a value from 0 - 65535. A lower numerical value means the bridge has a higher priority. Thus, the highest priority is 0. The default is 32768. Path Cost This specifies the cost of the port's path to the root bridge. 802.1W prefers the path with the lowest cost. You can specify a value from 1 - 20,000,000. Click Modify to modify any port. Click Apply to save the configuration. PowerConnect B-Series FCX Web Management Interface User Guide 127 53-1002268-01

RSTP Bridge Parameters
Vlan
The port-based VLAN that owns the STP instance. VLAN 1 is the default
VLAN. If you have not configured port-based VLANs on this device, all
802.1W information is for VLAN 1.
Priority
The preference that STP gives this port relative to other ports for forwarding traffic out
of the spanning tree. A higher numerical value means a lower priority.
Max.Age
The number of seconds this device or VLAN waits for a hello message from the root
bridge before deciding the root has become unavailable and performing a
reconvergence.
Hello Time
The interval between each configuration BPDU sent by the root bridge.
Forward Delay
The number of seconds this device or VLAN waits following a topology change and
consequent reconvergence.
Forced version
The configured force version value. One of the following value is displayed:
•
0 – The bridge has been forced to operate in an STP compatibility mode.
•
2 – The bridge has been forced to operate in an 802.1W mode. (This is the
default.)
RSTP Port Parameters
Vlan
The port-based VLAN that owns the STP instance. VLAN 1 is the default
VLAN. If you have not configured port-based VLANs on this device, all
802.1W information is for VLAN 1.
Port Admin Edge
If set to enabled, then the port becomes an edge port in the domain.
Port Admin Pt2pt Mac
If set to enabled, then a port is connected to another port through a point-to-point link.
The point-to-point link increases the speed of convergence. This parameter, however,
does not auto-detect whether or not the link is a physical point-to-point link.
Force Migration Check
The force-migration-check parameter forces the specified port to sent one RST BPDU. If
only STP BPDUs are received in response to the sent RST BPDU, then the port will go
return to sending STP BPDUs.
Priority
This specifies the priority of the bridge. You can enter a value from 0 – 65535. A lower
numerical value means the bridge has a higher priority. Thus, the highest priority
is 0. The default is 32768.
Path Cost
This specifies the cost of the port’s path to the root bridge. 802.1W prefers the path
with the lowest cost. You can specify a value from 1 – 20,000,000.
