Hi List,

Just a quick one to check that I do not need to configure something extra for this to work?

We have lots of Pseudowire’s configured using IOS-XR, IOS-XE and IOS, and these all show in Observium with the pwID, and the Local and Remote details (so Observium is correctly matching the stanzas across the two endpoints as being the same service) which is awesome J

However when configuring ‘Backup’ Pseudowire, the standby/backup Pseudowire is shown as ‘Down’ and ‘Alert’ in Observium?

This is really confusing for support staff who do not understand if down/alert means something is wrong or not, and as such we are currently unable to monitor any pseudowire and have all alerts disabled for them L

The attached image shows an example, of how all the PWs to the secondary device are reported as down and in an alert state! They are all down but in the normal state as standby/backup pseudowires.

Below shows the output for the PW states, and it can be seen that a status of ‘sec’ and ‘SB’ is provided for Standby/Backup (the Pseudowire is explicitly configured with a ‘Backup’ path etc) pseudowires.

IA sec   ac Po20.339:339(Eth VLAN)       UP mpls <remote-rt-2-ip>:339             SB

UP pri   ac Po20.341:341(Eth VLAN)       UP mpls <remote-rt-1-ip>:341            UP

IA sec   ac Po20.341:341(Eth VLAN)       UP mpls <remote-rt-2-ip>:341             SB

UP pri   ac Po20.348:348(Eth VLAN)       UP mpls <remote-rt-1-ip>:348            UP

IA sec   ac Po20.348:348(Eth VLAN)       UP mpls <remote-rt-2-ip>:348             SB

So the question I guess is, do the OIDs show the third status of ‘SB’ (or the ‘XC’ and ‘ST’ states of, ‘IA’ & ‘sec’ = Standby/Backup etc) so we can have something like; ‘UP’ = Green (Up), ‘SB’ = Amber (Up), ‘DN’ = Red (Down/Alert)?

Without this pseudowire alerting and state monitoring is broken L

As always, Thanks for all your time and effort with Observium

Kind regards, Andy.
