6.13.2.5 Show EPS Control Ring Map
Once a valid control ring is configured, selecting the Network VLAN and right clicking on Show (Detached) Map brings up an
icon map that shows the devices and links and their associated states. This figure can also be shown by clicking on the
Network VLAN under the VLAN Network node. Refer to the following figure.
FIGURE 6-113 Control Ring Map
If a VLAN Interface (VLAN IF) has been added to an EPSR Domain on a device, then the Vlan Map symbol for that control
VLAN IF will show its Domain role, either Transit or Master, above the symbol.
The state of the EPSR Domain is reflected in the color of the text of the domain role as follows:
For a Master VLAN IF:
• IDLE is gray (This indicates that the Domain is disabled)
• COMPLETE is green
• FAILED is red
Note: For AlliedWare Plus devices, which include the SB x908, x900-12X and -24X series, the initial state of the master node is idle
(gray), and turns to green only after the associated transit nodes have been discovered. The amount of time this takes
depends on the number of transit nodes that make up the ring.
For Transit VLAN IF;
• IDLE is gray (This indicates that the Domain is disabled)
• LINKS-UP is green
