Port Mobility Issue

[amel632]

Hi everyone. I'd like your support trying to explain why happened this following anomalous behavior.

Our end customer has a stack of four OS6400 with version 6.4.5.516.R01. They have configured port 1/31 as follows for mobility:

vlan 4 mac 00:1b:21:58:a3:86
vlan port mobile 1/31
vlan port 1/31 default vlan restore disable
vlan port 1/31 default vlan disable

With this configuration we're expecting that just the customer with mac address 00:1b:21:58:a3:86 will be assign vlan 4, but this customer reported that had limited connectivity. The administrator of the network sent me the evidence that I attached here.

From this evidence I see that the output of the command show mac-address-table 1/31 displays the mac 00:1b:21:58:a3:86 assigned to vlan 200 that It's the default vlan configured. This behavior is anomalous. But the output of the command show vlan port 1/31 displays vlan 4 assigned to this port and forwarding state, so this is confusing.

I hope I was clear with my explanation, if don't, please ask me anything.

Thanks

Can you dump the whole switch configuration in here ?

Thank you.

Hi,
Is the connictivity issue from seeing from the start? Or did it work fine first, and after some time the behavior was seen?

What are the reason for this command: vlan port 1/31 default vlan restore disable ?
this will be used for silent devices (like Printers).

regards
Silvio

amel ,

I'd rather you copy and past the conf in a new post.
I do not download files usually.

Hi Silvio.

Yes, our end customer has this command configured for silent devices, but they decided to use this configuration for all ports that use mobility.

Frank, I tried to posted but the configuration is too long.

Thanks.

Hi Silvio.

About your first question, the mobility was working fine and suddenly ocurred this issue.

Did you try adding the command

vlan 4 port 1/31

..?
