If
Apply Protection Domain is chosen, the devices that use the Network VLAN are included in the Configure EPS Control
Ring window, and in configuring the Control Ring the AlliedView NMS will complete the loop.
Create New Protection
VLAN Domain Dialog
Protection Domain - The name of the domain that will include all of the devices that are
part of the Network VLAN. Naming conventions are up to 15 characters (spaces not
allowed).
Hello Time and Failover Time - Refer to 6.13.1.3.

EPSR Protection
Domain panel
Lists the relevant information for the control ring: Have control over columns that are
enabled. (Controllable fields in bold.)
Device: The name of the device as defined in the Managed Object Properties
Domain Name: The domain name that applies to this specific Network VLAN and all of its
associated nodes.
Control VID: The VID of the network VLAN that is being used to create the protection ring.
Interface #1/Primary - Can toggle between Primary and Secondary.
Interface #2/Secondary
Is Master: Selects which device is to be the master node. This is usually the node that is
connected to upstream devices. (This cannot be modified if you are modifying an existing
control ring.)
Operation Type: The operation (such as Create) that is being applied to the ring configura-
tion.
Is Enabled: Checked by default, allows the user to disable the EPS domain for that device.
Note the ring (master node) should be disabled only to perform a configuration change.
If the master is disabled, the ring will not provide protection. It appears that the device
blocks both ports so it no longer is connected to the other devices (and the ring is broken).
If the transit is disabled it also appears that the device blocks both ports for protected traffic
so it no longer is connected to other devices (although the ring except for that device will
still function).
EPSR+ - ENHANCEDRECOVERY, which can set to ON (checked) or OFF (unchecked) if
the node supports this feature. If the node is not running NSP release 12.0 or above, the
checkbox is disabled. If all nodes support EPSR+, they are all initially checked.
Device Operations Options to perform on the created control VLAN:
Apply Protection Domain - Configures the devices to support the control ring. Brings up
the Task Details window.
Delete Protection Domain -Activated only when the EPS Control Ring has already been
created, allows the user to delete the protection domain for the network VLAN. Note that
the network VLAN itself is not deleted. Refer to 6.13.2.3.
Modify Protection Domain - Activated only when the EPS Control Ring has already been
created, allows the user to modify the protection domain for the network VLAN. Refer to
6.13.2.3.
Enable/Disable - Activated only when the EPS Control Ring has already been created,
allows the user to disable the protection domain after it has been applied, and vice versa.
Refer to 6.13.2.4.
