• Link Layer Discovery Protocol or LLDP.

If the phone 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 46xxsetting file and the network file server

fails, the phone will not be able to read the MCIPADD value or any of the 46xxsettings file

parameters. Therefore, do not use this method of providing MCIPADD.

Proposed Solution

Procedure

1. A more robust way to provide this value is to use DHCP. You can administer the DHCP

server to provide MCIPADD using DHCP Option 242. You can also administer the

TLSSRVR, HTTPSRVR and L2QVLAN parameters using this option. phones using non-

static addressing automatically use the DHCP request method. Option 242 is the default

DHCP offer and may get MCIPADD and other addresses using this way.

2. The phone displays the Waiting for LLDP message when both the HTTP and HTTPS

Server IP address are not administered. To administer the HTTP and/or HTTPS server,

use the Craft ADDR procedure and enter the correct HTTP and or HTTPS File Server IP

address in the File Server field.

3. An alternative protocol known as LLDP can also supply call server, and file server with

HTTP and HTTPS IP addresses. This IETF standard protocol requires the network to be

equipped and configured to support LLDP. You can provide HTTP and the HTTPS Server

and call server IP addresses with LLDP in the network using proprietary Transport Layer

Values (TLVs) to pass information to the phones.

LLDP setup and troubleshooting steps

Note:

If system value

STATIC is set to 0 which is the default setting, the DHCP or the 46xxsettings

file might overwrite the static addresses.

details on how to set “STATIC” to use manually programmed IP addresses.
