Connect 4850 with HP procurve 2848
« on: October 10, 2014, 11:19:36 AM »
Hi ALL
I need to connect a Avaya 4800 to a HP procurve , under 2 or more cables ( for having at least 2GB agregate speed between them).

How is this accomplish ? Or can I connect a cable directly between them , without any config changes?

Should we use link agreggation? are they compatible?
Regards

You can use a staic link aggregation, wich is called MLT at your ERS4800 or an dynamic
LACP Trunk between your two switches.
You will need to make the configuration on both of your switches , before you connect the second cable.

Hi

MLT i know it from Avaya. I can configure an MLT on 2 or 3 ports.

 and on the HP procurve is called what? LACP?
Thanks for the help ;)

If you had 2 Avaya switches the recommendation would be to use MLT between them - it has several benefits to LACP.

However, in your case you have a link between Avaya and HP. I think the recommendation here would be to use LACP on both sides as there might be compatibility issues in linking MLT to LACP.

You can also look into replacing the HP Procurve.  ;D

I believe MLT is compatible with Cisco's Etherchannel.

Remember.  MLT and Etherchannel are proprietary.  LACP is an industry standard - 802.3ad
