Layer 2 VLAN From Avaya VSP7024 to Extreme/Avaya VSP4850

[MJS]

Greetings HUB Community,

We have a VSP7024 which was configured prior to my involvement. It is behaving as a BCB in an SPBM environment connecting about 15 VSP 4850s in a hub/spoke configuration. System has been working flawlessly.

We recently acquired 8 Windows Servers that we plan on connecting via available 10Gb SFP+ interfaces on the VSP7024. When I took a look at the initial configuration of the 7024, all the ports were configured for ISIS/SPBM connections. I removed the ISIS/SPBM configuration from ports 6 and 8 (where a pair of Windows servers will connect), created vlan 150 and assigned that vlan to the ports. I added an i-sid designation for vlan 150. as well.

On the VSP 4850 I created vlan 150 and assigned that vlan to port 1 (our test laptop). I added the i-sid as well for vlan 150. Seemed simple enough. I can get the servers to ping each other locally. I can get the laptop to ping the 4850 and vice versa. However, I cannot get a successful ping across the SPBM interface. Both switches show vlan 150, both are recognizing the i-sid for vlan 150 (10150) and there is an established ISIS adjacency. Firewalls have been disabled.

I have extracted some relevant config and output info from the 2 switches for your review. Getting ready to involve TAC, but I wanted to start here.

Thanks for the support all. For future searches, a software upgrade from 10.4.0 to 10.4.6 solved the issue.

Not sure exactly what I am looking at when I run that command (show isis lsdb detail), but I don’t see any incorrect addressing as far as I can tell.

Got a TAC engineer looking into it. Thanks Martin.

Hmm, the VLAN settings on the ports is fine.  I guess the unreachable servers have IP addresses 10.10.150.21 and 10.10.150.22?  The ARP table contains those records.  I have seen the similar problem on VSP 7024.  Other switches in fabric had wrong Chassis MAC for that VSP 7024 is LSDB.

I suggest checking show isis lsdb detail on VSP 4850.  Check Chassis MAC for VSP7K.1.

Thanks for the reply Martin. Here’s the output (sorry about the formatting):
