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 Klaus,

can your explane your situation in more detail, please?

For example, you write the phones cannot reach your TFTP server.  It would be helpful to know what is working, too.
E.g. if the basic communication works.

Can clients reach each other (in the same VLAN/I-SID and in different VLAN/I-SIDS).

Is the TFTP server pingable.

What else does not work.

How are the XOS switches connected to the VSP? Do you use a fabric? Are the VSP7400, the X460 and the X440 connected in one line or in parallel? ...

Hello everyone,

Cannot open a new topic so I was hoping I could ask the question here.

I am having some issues when connecting switches like this:

VSP7400 - x460G2 - x440G2.

Phones on the x460 and the x440 cannot find their TFTP server for instance.

Software on the VSP: 8.2.6.0
Software on the x460 and X440: 22.7.1.2-patch1-17

Can anyone point me in the right direction?

Thank you,

Klaus

Tfsnetman,

You could always use the TAB or “?” to clear the current line

Hi Mig,

Totally agree with “automatic return” - poor choice of words.

I just meant the console or ssh session to come back to where I left it - so I can see where I was with my typing  .

I found SecureCRT to be very stable both OS X and Windows.

Cheers, Klaus

Klaus,

We don’t have a solution for this cosmetic issue. A tuned console client can do the job but...

Personally I don’t like the automatic return key. It could happen in the middle of a command line.

I use RoyalTSX as console client and a plug-in based on iTerm can be configured for this.

Be careful anyway.
