Standard Configuration for smlt-virtual-bmac and smlt-peer-system-id

[rrrgamara]

Hi,

I am trying to configure v-IST to a 7520 switch and I noticed that smlt-virtual-bmac and smlt-peer-system-id is required on the configuration. What is the most efficient way to identify the values for both?

Thank you.

Hello,

I always do it this way.

I try to design a address schema that, in the positions after 0049., includes all that is applicable like site ID, Rack location ID, the switch function and switch number in that location.

First SMLT cluster member

system-id 0049.xxxx.xxx1
spbm 1 smlt-virtual-bmac 02:49:xx:xx:xx:x1
spbm 1 smlt-peer-system-id 0049.xxxx.xxx2

Second SMLT cluster member

system-id 0049.xxxx.xxx2
spbm 1 smlt-virtual-bmac 02:49:xx:xx:xx:x1
spbm 1 smlt-peer-system-id 0049.xxxx.xxx1

• I use as "smlt-virtual-bmac" the "system-id" from the first cluster member and change the second character from "0" to "2", which makes the "smlt-virtual-bmac" a "locally administered" MAC address.
• As "smlt-peer-system-id" the smlt partner "system-id" is used.

This makes the backbone MAC addresses recognizable.

Hope it helps

Hello,

Forgot to include, for the "virtual" "VLACP SMLT -SYS-ID" I use (again) SMLT cluster unit one's "SYSTEM-ID" and change the seconf character to "6".

lacp smlt-sys-id 06:49:xx:xx:cc:x1

hope it helps
