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

Hello tfsnetman,

I think you will find the answere here (last message):

https://community.extremenetworks.com/extremeswitching-vsp-ers-232923/voss-console-messages-in-curre...

The command is  '”logging screen enable'”  hen you use telnet and ssh session.

Hi Mig,

While I want logging on the console I also want the system to press the return key for me like this:

Core-1-Hv:1(config)#1 2020-10-20T21:50:18.464Z Core-1-Hv CP1 - 0x00088524 - 00000000 GlobalRouter SW INFO Boot sequence successful

Core-1-Hv:1(config)#

instead of this

Core-1-Hv:1(config)#1 2020-10-20T21:50:18.464Z Core-1-Hv CP1 - 0x00088524 - 00000000 GlobalRouter SW INFO Boot sequence successful.

Klaus,

I’m not sure to fully understand your question but…

To have the on/off the console messages on console or SSH session on:

• VSP: 
  • configure terminal
  • logging screen
  • no logging screen
• EXOS
  • enable log display
  • disable log display

Hi Mig, Stephan,

Thanking you both for your replies.

Cosmetical question:

• Is there a way to have console messages synchronised and the prompt being shown after the message?

On a Cisco I would configure logging synchronous on line con 0 for instance.

Kind regards,

Klaus

Hello Klaus,

your option one should work fine. You can have links with tagged vlans from the fabric to other (non fabric) switches. After you establised the connection between Fabric and Cisco, you can move your x460 switch by switch. 

In an third step you can move the routing interfaces from cisco to the fabric.

Best regards

Stephan
