FA from VSP 7254 to ERS 4950 displaying individual ports

Configterminal — Wed, 20 Mar 2024 19:46:10 GMT

Hello, I have an ERS 4950 (Ports 1/49-50) connected to a VSP-7254 VOSS Switch (Ports Gig1/17-1/18) using fabric attach. Everything works fine but I was just wondering if this is correct as on the ERS side when I run "show fa elements" I'm seeing the Unit/Port as MLT1 (which I expect):

ERS:

===============================================================================
UNIT/ MGMT ELEM ASGN
PORT TYPE VLAN STATE SYSTEM ID AUTH AUTH
-------------------------------------------------------------------------------
MLT1 Server 92 T / S 00:10:00:00:6d NA NA

===============================================================================
Fabric Attach Authentication Detail
===============================================================================
UNIT/ ELEM OPER ASGN OPER
PORT EXPANDED TYPE AUTH STATUS AUTH STATUS
-------------------------------------------------------------------------------
MLT1 Server (NoAuth) successNoAuth successNoAuth

But on the VSP side when I run that command I see the individual ports and not the MLT although it is definitely configured:

VSP:

====================================================================================================
Fabric Attach Discovery Elements
====================================================================================================
MGMT ELEM ASGN
PORT TYPE VLAN STATE SYSTEM ID AUTH AUTH
-----------------------------------------------------------------------------------------------------------
1/17 proxyNoAuth 92 T / S 00:20:00:00:01 NA NA
1/18 proxyNoAuth 92 T / S 00:20:00:00:01 NA NA

MLTID NAME CREATED PORT MEMBERS PORT MEMBERS IN DATA PATH
-----------------------------------------------------------------------------------------------------------
109 MLT9 LOCAL 1/17-1/18 LOCAL

Is this expected?

Hi ConfigTerminal,

Yes, it sound normal.

You should also check the FA interfaces ("show fa interfaces") on the VSP side. It should display the MLT109 as FA interface.

So it does i fact display MLT109 rather than the individual ports. I just found it strange it displays differently between ERS and VSP but I guess different code bases. As long as it's expected thats fine.

Thanks
