Suggestions for Tagging a management vlan over an ISIS/SPBM link.

[ItsJaredKushner]

Hello!

I have a scenario that involves two UISP antennas that will be linking together a 5420 to a 5320. 

I'm able to establish adjacencies with no issues, but unfortunately the unifi p2p's do not include a separate physical management interface. 

Is there a way to tag a management vlan over an ISIS/SPBM interface? 

[ItsJaredKushner]

I've setup a logical interface on the two switches. However, when attempting to tag the management vlan for the UISP antennas, I get this. 

There is a successful adjacency with the logical interfaces going over the UISP antennas. The Logical interfaces currently are using vlan 10 and 20 (following the illustration you posted). 

did I set something up wrong?

Could you please clarify the following for us?
Would you like to establish a Fabric Connect connection between a 5420 and a 5320 via UISP antennas? Would you also like to use the uplink from the switches to these antennas as an uplink for the management interface of the UISP antennas?

Would you like to establish a Fabric Connect connection between a 5420 and a 5320 via UISP antennas? : 

The answer to this question is yes. I am successfully able to form adjacencies over the UISP antennas, but I don't have the ability to tag a management vlan to the UISP antennas and manage them.

Would you also like to use the uplink from the switches to these antennas as an uplink for the management interface of the UISP antennas?

To answer this, yes. I would like the ability to manage these antennas and transit fabric connect over a single interface.


In a traditional trunking scenario, this isn't an issue.

The solution would be to tag classic VLANs on that port: one VLAN for management of the antennas themselves and one VLAN for an IP transfer network for a L3 Fabric Extend connection. In theory, this should work. However, I haven´t tested it and it would be interesting to see if it works.

nevermind. 

Overlooked the MTU settings on the p2p antennas. 

The L3 fabric extend configuration works as intended now. 

And I have working management access to the antennas. Thank you Phil!
