Fabric SPB migration from Cisco core

[tfsnetman]

Hello,

I was wondering whether someone did migrate from a standard 802.1q tagged core like Cisco to a Fabric SPBM with VSP 7400 series and would like to share their lessons learned.

Currently:

Cisco 4500x cores -- X460G2-10GE4 (distribution / edge)

Future:

VSP 7000 -- X460G2-10GE4 (fabric attach)

Options I can think of:

1)

VSP 7400 --- Cisco 4500x

• not sure how to have 802.1q tagging between VSP 7400 and Cisco 4500x and SPBM at the same time
• Migrate all X460G2 from Cisco 4500x to VSP7400

2)

VSP 7400 --- x460G2-10GE4 --- Cisco 4500x

• the x460G2 would be a fabric attached client on the VSP7400 side and a standard 802.1q trunking client on the Cisco 4500x side.
• migrate all remaining X460G2s to the VSP7400 as fabric attached units

Your thoughts?

Thank you,

Klaus

Hi Klaus,

In fact you must have all the vlan/i-sid provisioned on both cluster members even if no ports are assigned to a vlan on one cluster member.

This is due to the fact they announce themselves in the fabric with a virtual bmac and then they both can receive packets for any i-sid announced.

When you configure the virtual ist, you get the following warning:

CAUTION : All the C-VLANs need to have an I-SID associated with it.

Hello,

Lesson learned: If you have one VSP cluster member connected to a Cisco with a static Vlan / I-SID configuration, make sure you have that same configuration on both VSP cluster members.

Hi Stephan,

Everything works fine when connected like this:

VSP7400 - x450G2

VSP7400 - x440G2

When connecting VSP7400 - x450G2 - x440G2 in one line I am having issues.

Assumption:

The VSP7400 is acting as a FA server, the x450G2 as a FA Proxy and FA Client (for the VSP) and the x440 is a FA client again.

Questions:

• Do I have to map vlans to ISIDs / NSIs on the x440?
• What about the uplink on the x450 to the x440? Do I tag all Vlans or do I use LLDP to advertise / request them?
  • Or should I disable LLDP and treat the x440 like any other switch?
• Do I need version 30.x on the x450 and x440 so I can configure FA Proxy?

Thank you,

Klaus
