Avaya 9608 and Cisco SG switches and LLDP

[bishoptf]

New to the forum but looked like the best place to ask some technical questions concerning Avaya. Some background...I support my church after hours and have just helped them go through a evaluation to replace their unsupported Nortel system. I am a Network Engineer by day so the plan was for us to support the network and upgrades, pull wire and terminate and have the vendor just come it and set phones and program things up.

I have installed a mix of sg300 and sg500 cisco POE switches and all appears to be well. My setup for the network config consists of a trunk port with data on the untagged, and voice on a separate tag vlan. I have turned off all of the Cisco smart port stuff and manually configured up LLDP, creating a policy for voice that provides the voice vlan and sets the priority, then applied the policy to the user ports. The plan was to use LLDP tell the phone what vlan to come up in instead of using DHCP options, which I can do but would prefer to use LLDP.

Now being that I am a network guy I wanted to play with stuff before the install and make sure things were working properly before the vendor comes in and I just like understand how things are working so I went and bought a used 9608 off of ebay for cheap and I am playing with that. So I have the phone hooked up to a port and I am mirroring the port and sniffing with wireshark to see the traffic.

So here is what I am seeing, the phone boots up and I se broadcast packets coming out looking for DHCP but I do not see any LLDP packets come from the phone, eventually I see a LLDP packet that comes from the switch but I never see any LLDP packets coming from the phone saying its a phone etc..so it therfore comes up on the data vlan. Now being new to Avaya (from a cosco shop) I am trying to learn more about the phone and being that its a used phone, should I do a hard reset on it, I came across the CRAFT# procedure but I haven't done any real resets on it just unplug and replug power.

Sorry for the long post but wanted to gove some detail, if anyone has any ideas of where I can go to read or has questions let me know, thanks in advance.

Hi,

I am not very familiar with sgxx line of product but here is a sample in 2960 config:

-------------

lldp timer 10
lldp holdtime 30
lldp reinit 5
lldp run

interface FastEthernet0/1
description --- IP Phone Ports ---
switchport access vlan 5
switchport voice vlan 100
spanning-tree portfast
end

In this case vlan 5 is data lan, vlan 100 is voice lan.

I believe that 9608 , initially has some issue with its bin file and just
wonder if you have yours with the lastest load.

LLDP should be on by default from the phone side. Once it sees an lldp advertisement from the switch, it would reply . Do not use lldp and dhcp option at the same time as the phone would be confused

Yeah I have read through most of that and think that I have the cisco's configured properly...I see LLDP packets coming from the switch but never see any LLDP packets from the phone...none, even when booted up I did som LLDP sh commands etc and nothing appears from the phone...

I think I am going to try to reset the phone using the CRAFT# and reset to factory and see if that changes anything...

Are the MAC id's (first 6 digits) of the phones in the switch? If not the LLDP won't work.

Why would the phone MAC ID's show up on the switch, I have turned off all of the auto voice vlan stuff on the switch, not using smartports or the OUI auto voice vlan stuff...just plain jane, untag data and tag voice. I then configured up a LLDP network policy for voice and applied to the ports.

I meant to say Why wouldn't the MAC's show up on the switch...

Yeah I have read this blurb before..."Activate the switch the telephone is connected to for LLDP. This is currently only possible with Extreme switches." Surely this is not still the case any more I have read folks using cisco and LLDP with avaya phones.

I did some more digging tonight and it appears that the firmware on th phone is really old...it is using s9608_11HALBR6_0_20SV_452.tar, from what I have read LLDP was not working if at all in the older versions. I have downloaded what I think to be the latest version S9608_11HALBR6_2_1_19U_V452.tar. I have set up a http server and copied all of the files, and I think if I manually set the ip and http server address it should pull down and upgrade the firmware, is that correct or do I need to do something else?

I have been successful in upgrading upgrading the firware to 6-2 firmware which is what I think is the latest release for the 9608, it will be a couple of days till I can go back to the church and test again with the cisco sg300 to see if it plays nicer with LLDP.
