28.1.4 Setting Control VLAN
- <Structure of this section>
(1) Setting Control VLAN
- Points to note
-
Specify the VLAN to be used as the control VLAN. The following VLAN cannot be set:
-
VLAN used for the data-transfer VLAN
-
VLAN ID equal to VLAN ID used in the different rings
-
Default VLAN(VLAN=1)
-
Command examples
-
(config)# axrp 1
Switches to axrp configuration mode for ring ID 1.
-
(config-axrp)# control-vlan 2
Specifies VLAN 2 as the control VLAN.
(2) Setting the Control VLAN Forwarding Transitions
- Points to note
-
Set the forwarding transition time for the control VLAN of a transit node for when the Ring Protocol is in the initial status. Set the forwarding transition time for the control VLAN on the transit node (set in forwarding-delay-time parameter) to a value greater than the protection time for health check frames on the master node. Also, set a value smaller than the flush control frame receive wait protection time (the value set in the configuration command forwarding-shift-time). If the ring port of the transit node enters the forwarding state before the master node detects recovery from a configuration error, a loop might occur temporarily.
Command examples
-
(config)# axrp 1
(config-axrp)# control-vlan 2 forwarding-delay-time 10
Sets the forwarding transition time for the control VLAN to 10 seconds.
