Avaya IP Office/ERS 5500&4500 Issue - IP Sets not booting up
« on: September 24, 2013, 10:15:31 AM »
Afternoon

Bit longwinded this one........

We have an issue where IP sets on a ‘Secondary’ site won’t boot up – the set simply just continues to display ‘restarting’.

'Voice VLAN' (VLAN 2): 192.168.38.0/24
'Data VLAN 1'(VLAN 1): 192.168.8.0/24
'Data VLAN 2'(VLAN 5): 192.168.67.128/25

We have an IPO located on the 'Voice VLAN' (192.168.38.9).
We have our PC running as the HTTP/HTTPS IPO 'Server' (192.168.38.10)
The IP Handsets (1608) are provided with IP Addresses from the 'Voice VLAN' subnet.
'Data VLAN 1' is used for our primary site to serve the PC estate.
The IP Sets (1608 & 1616) serve the connection of the PC through the built-in Ethernet switch - 1 LAN switch port is a member of 'Data VLAN 1' (PVID) and 'Voice VLAN'.
We have a DHCP Server (192.168.8.10) to serve out PC estate on 'Data VLAN 1' and our 'Voice VLAN'

DHCP Server (192.168.8.10) is set-up as follows;

'Data VLAN 1' Scope
Scope Option 242
L2Q=1,L2QVLAN=2,VLANTEST=0

'Voice VLAN' Scope
Scope Option 242
MCIPADD=192.168.38.10,MCPORT=1719,HTTPSRVR=192.168.38.10,VLANTEST=0

Now this set-up works fine. The 1608 is plugged into the LAN switch. DHCP request sent on Data VLAN 1. Scope option 242 provides the Voice VLAN ID and the 802.1q to On. The 1608 then requests an IP Address from the Voice VLAN which also on Scope Option 242 provides the IP Address of the IPO, etc. The handset then updates its firmware and we configure with the extension number and password. Simple and one-step process.

We now have a secondary site which is part of the same LAN but has been served with its own IP/subnet and DHCP server. We need to provide IP Handsets via the IPO to this secondary site.

DHCP Server has an IP Address of 192.168.67.200.
Each LAN switch port to serve the IP Handsets and PCs are a member of VLAN 2 and VLAN 5 (PVID).
We initially setup the DHCP Server with the following ;

'Data VLAN 2' Scope
Scope Option 242
L2Q=1,L2QVLAN=2,VLANTEST=0

The thought was that the IP Handset would boot and obtain an IP Address from DHCP Server 192.168.67.200. It would then receive the Scope option 'L2Q=1,L2QVLAN=2,VLANTEST=0 which would tell the IP Set that 802.1Q would be set to On and the Voice VLAN is on VLAN 2. I then thought it would broadcast for an IP Address on VLAN 2 which means it would then look to DHCP Server 192.168.8.10 to be provided with its 'Voice VLAN' IP Address.

The IP Set seems to pick up the Data VLAN IP Address with the VLAN ID=2. However the set then displays 'restarting' before following the same process. This process seems to loop over and over and never boots – it never seems to receive an IP Address within the ‘Voice VLAN’.

Rather than using DHCP Server 192.168.8.10 to provide 'Voice VLAN' IP Addresses for the secondary site we have then built a 'Voice VLAN' scope on DHCP Server 192.168.67.200. The 'Voice VLAN' scope on DHCP Server 192.168.67.200 provides addresses from 192.168.38.200 - 192.168.38.250.

DHCP Server (192.168.67.200) is now set-up as follows;

'Data VLAN 2' Scope
Scope Option 242
L2Q=1,L2QVLAN=2,VLANTEST=0

'Voice VLAN' Scope
Scope Option 242
MCIPADD=192.168.38.10,MCPORT=1719,HTTPSRVR=192.168.38.10,VLANTEST=0


However this hasn't changed anything - still seems to pickup the fact it needs to broadcast on VLAN 2 but then just keeps restarting over and over again.

The only manual way we have found to get this to work is to manually change the 802.1Q setting within the IP Handset to 'On'. The handset will then boot normally. However even with changing this setting to 'On' it can take a number of restarts of the IP sets before it boots to enable the entry of the extension number and password.

I'm pretty sure this is a LAN switch issue but can't quite figure out the problem.

We simply want to plug the IP sets into the LAN switch on the Secondary site without any manual or convoluted process – basically to match the process on the Primary Site (Plug and Play – with just the extension number and password being entered).

Our LAN estate is as follows;

I would setup a port mirror and see exactly what the IP phone is requesting and what answers it's getting from the DHCP server and network.

You have the same firmware/software loaded on the Avaya IP phones at each location?

Good Luck!

Thanks for the response Michael.

I have been revisiting this one on a couple of occasions when I had the chance.

Changed the management VLAN and IP Address on the 'problem' site to match the rest of the LAN (192.168.8.20). Also tested in other parts of the LAN on the relavent VLANs (connecting an IP set on another switch to either VLAN 1 or 5 as the PVID with VLAN 2 'secondary' VLAN) worked fine. Everything pointed back to the new switch or switch configuration. The switch at the 'problem' site had a higher code release than the others - running 5.6 on the 4550, while the rest are running 5.4.

Installed a replacement switch running 5.4 and this seems to have rectified the problem. IP Sets connect and boot up first time regardless if they have an older release straight out the box. I had also removed some of the configuration that was running on the new switch which isn't on the rest (historic reasons), such as rate limiting (Multicast/Broadcast), Spanning-tree bpdu-filtering, etc.

Would be surprised if the configuration caused the issue but will look into this in more detail when time permits.

There is a command you need for the newer software releases to get ADAC/LLDP-MED to work properly, you essentially need to disable the default LLDP policy but since you are using DHCP to assign the voice VLAN this shouldn't be an issue for you.

Are you utilizing DHCP or ADAC/LLDP-MED?

Here's the command;


interface fa ALL
 no lldp med-network-policies
exit

Hi Michael

We aren't using ADAC/LLDP-MED, which we do use at all other sites, due to the fact that is isn't supported by the 16xx sets.

We use scope option 242 within DHCP to serve the IP Address, VLAN, Switch Information, etc but just set the ports to trusted - in the same way as our uplink ports to our core switch.

Not ideal but will work at the moment until I get a chance to re-visit.

Cheers again.

You can do ADAC-MAC - we do that as our standard.  We have started testing ADAC-LLDP, but on a limited basis.  Just have the range added - adac mac-range-table low XX.XX.XX.00.00.00 high XX.XX.XX.FF.FF.FF
