LLDP Troubleshooting

If the "Waiting for LLDP" message appears for more than a few seconds, it generally indicates
a problem with getting a value for the Call Server IP Address. This can occur due to incorrect
settings in script files or in the way the network has been configured.
When the telephone boots, it expects to find a valid IP Address for the Call Server. This value,
known as MCIPADD, can come from several sources:
• A static or manually programmed address on the phone.
• The 46xxsettings.txt file MCIPADD setting.
• A DHCP offer using option 242 that includes the MCIPADD setting.
• 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 "
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.

Proposed Solution

1. 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
Cause/Resolution
CAUSE: Most likely, WMLPROXY and/or
WMLPORT have not been properly
administered.
RESOLUTION: Administer the missing data in
the 46xxsettings file, as indicated in the Avaya
one-X™ Deskphone H.323 Administrator
Guide.
