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 Administration menu 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.
For more information about LLDP processing, see Administering Avaya B189
Conference IP Deskphone, 16–604294.
LLDP setup and troubleshooting steps
For manually programmed deskphones, use the Administration Menu ADDR procedure to set
the call server to a valid IP address. For information on entering the IP addresses using the
ADDR procedure, see
Changing IP address information on page 29.
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.
Note:
See Administering Avaya B189 Conference IP Deskphone, 16–604294, for details on how
to set “STATIC” to use manually programmed IP addresses.
