6.13.7 Status of Transit Nodes for AlliedWare Plus Devices
When AlliedWare Plus devices, which include the SB x908, x900-12X and -24X series, are included in the EPSR ring as
Transit Nodes, their state may or may not reflect any changes that may have occurred. This occurs because the devices fail
to send a trap when the EPSR state changes. As a result, only a rediscovery of the nodes can guarantee that the state
reflected in the GUIs (such as when selecting Network Inventory -> EPSR Domains) is correct.
