Error: SMLT VLAN must have i-sid association.

[Anonymous]

Hi,

Getting the error below but can’t understand what it is requiring me to do:

Error: SMLT VLAN must have i-sid association.

The VIST is up an running:

Equally the VIST VLAN 4053 has a valid I-SID:

This is the configuration I am adding, and where the error displays:

Many thanks in advance

Ah, well spotted!

That’s caught me out before, those ports should have already been removed from VLAN 1

Removed VLAN 1 from those ports and all now sorted.

Thanks for the insight.

Cheers,

Martin

Martin,

I see the VLAN 1 provisioned to the port 3/1.

Hi Mig,

Thanks for posting a reply.

Provided a small portion of the output below you requested, it covers interface 3/1 in the example above showing VLANs associated to the port and I-SID’s associated to the VLANs.

The MLT is using LACP, so no ports are directly associated to it yet (other then the LACP Key) being dynamic, hence no I-SID is currently directly tied to the MLT at this time - if I’ve understood that correctly.

When the interfaces come up and the MLT is dynamically formed then underlying port / VLAN assignment is then associated to the MLT I believe.

I’m obviously missing a step, but can’t put my finger on it as it all seems in place?

Hi Martin,

It seems that some VLANs configured on the port 3/1 or MLT 301 has no i-sid.

check it with :

show vlan member

show vlan i-sid
