Lldp Setup/Troubleshooting Steps - Avaya one-X 9600 Series Installation And Maintenance Manual

Troubleshooting Guidelines
Link Layer Discovery Protocol or "LLDP."
If the telephone cannot find MCIPADD through any of these means, it will fail to register with the
Call Server and will display the "Waiting for LLDP" message several times before
rebooting. For example, if the MCIPADD value was specified in the 46xxssetting file and the
network file server fails, the telephone will not be able to read the MCIPADD value or any of the
46xxsettings file parameters. Therefore, this method of providing MCIPADD is not
recommended.
A more robust way to provide this value is to use DHCP. The DHCP server can be administered
to provide MCIPADD using DHCP Option 242. (Note that TLSSRVR, HTTPSRVR and
L2QVLAN can also be administered using this option). Telephones using non-static addressing
automatically do a DHCP request (Option 242 is the 96xx default DHCP offer) and may get
MCIPADD (and other addresses) this way.
Another reason for receiving the "Waiting for LLDP" message is that the File Server IP Address
is not administered. To administer the File Server, use the Craft ADDR procedure and enter the
correct HTTP/S File Server IP Address in the File Server field.
An alternative protocol known as LLDP can also supply call server and file server IP Addresses.
This IETF standard protocol requires the network to be equipped and configured to support
LLDP. With LLDP in the network, File Server and Call Server IP Addresses can be provided
using proprietary TLVs (Transport Layer Values) to pass information to the telephones. See the
Avaya one-X™ Deskphone Edition for 9600 Series IP Telephones Administrator Guide for
detailed information about LLDP processing.

LLDP Setup/Troubleshooting Steps

For manually (statically) programmed telephones use the Craft ADDR procedure to set the Call
Server to a valid IP Address.

If system value "STATIC" is set to "0" (the default), static addresses may be

Administrator Guide for details on how to set "STATIC" to use manually
programmed IP Addresses.
For DHCP configured telephones:
1. Using the local (Craft) ADDR procedure, set "Phone" to 0.0.0.0.
2. Verify or set SSON to 242 (this is the default).
3. Administer the DHCP server option 242 to contain "MCIPADD=xxx.xxx.xxx.xxx", where
xxx.xxx.xxx is the Call Server IP Address.
