How to setup 1120e and 5520's with LLDP
« on: October 19, 2013, 08:36:25 AM »
Hi

We have about 100 1120e phones connected to  Avaya 5520 switches running v6.1.2 firmware. I used one of Michael's earlier blogs to set them up and its worked very well using an ISC DHCP server. LLDP is configured on the switch and a voice vlan defined in ADAC

We recently upgraded a switch to firmware v6.3.2 and it now no longer works. The switch ports no longer seem to be able to configure the ports correctly. The port does switch to a the voice vlan, but dhcp requests for VoIP seem to come in on the PVID vlan (i.e our data vlan). I see in the release notes for 6.3.2 that there have been lots of additions to 802.ab.

So first question, what do I need to do to get the 1120e phones working with v6.3.2

Second question. while looking around to solve this I came across this posting

https://forums.networkinfrastructure.info/nortel-ip-telephony/again-nortel-ip-phone-and-the-dhcp-auto-config-challenge/

In this posting Michael refers to using LLDP-MED instead of DHCP. What does this mean exactly, Does it mean I still need a DHCP server to hand out IP, but I can specify all the phone and call parameters in the switch now. Is there an example how to do this?

thanks
Steve

You upgraded a working configuration or you configured a new switch which had already been upgraded?

There's a big difference... you can check out this updated post;

http://blog.michaelfmcnamara.com/2013/02/avaya-ethernet-routing-switch-4800-series-configuration-template/

There are multiple pages to that post so make sure you read all 3 pages.

If you are configuring a new switch you need to remove the default LLDP profile or it will interfere with the LLDP-MED profile;


interface fa ALL
 no lldp med-network-policies
exit


Good Luck!

Thanks for the Blog references.

This was a working switch that was upgraded from 6.2.x to 6.3.2.
We managed to resolve the issue, pays to read the earlier release notes in 6.3.0

thanks
