21 Settings and Operation for the Ring Protocol
command). If the ring port of a transit node is changed to the forwarding status
before the master node detects restoration from an incorrect setting, a loop might
occur temporarily.
Command examples
1.
(config)# axrp 1
(config-axrp)# control-vlan 2 forwarding-delay-time 10
(config-axrp)# exit
Sets the forwarding transition time for the control VLAN to 10 seconds.
21.1.5 Setting VLAN mappings
(1) Setting new VLANs
Points to note
VLANs used for data transfer can be bound to a VLAN mapping. A single VLAN
mapping can be used on multiple rings as a common definition. As many as 128
VLAN mappings can be set. Multiple VLANs can be set for a VLAN mapping by
using lists.
The VLAN for data transfer used within a ring network must be the same for all nodes.
However, because only VLANs for VLAN mappings specified for VLAN groups need
to match, there is no need to match the VLAN mapping IDs for all nodes in a ring
network.
Command examples
1.
(config)# axrp vlan-mapping 1 vlan 5-7
Sets VLAN IDs 5, 6, and 7 for VLAN mapping ID 1.
(2) Adding VLANs
Points to note
VLAN IDs can be added to VLAN mappings already set. When the ring to which an
added VLAN mapping is applied is running, the mapping is reflected immediately.
Also, when additions are applied for multiple rings, they are all applied at the same
time. If a VLAN mapping is changed during ring operation, a loop might occur.
Command examples
1.
(config)# axrp vlan-mapping 1 vlan add 8-10
Adds VLAN IDs 8, 9, and 10 to VLAN mapping ID 1.
(3) Deleting VLANs
Points to note
A VLAN ID can be deleted from a VLAN mapping already set. If the ring to which the
deleted VLAN mapping is applied is running, the deletion is reflected immediately.
Also, when deletions are applied for multiple rings, they are all reflected at the same
time. If a VLAN mapping is changed during ring operation, a loop might occur.
Command examples
1.
(config)# axrp vlan-mapping 1 vlan remove 8-9
Deletes VLAN IDs 8 and 9 from VLAN mapping ID 1.
