b. Telephony LAN (TLAN) Node IP address: Enter the Voice LAN
(TLAN) Node IP address in dotted decimal format. The Voice
LAN Node IP address is on the TLAN subnet. The Node IP
address is the IP address used by the IP Phones to communicate
with the Voice Gateway Media Cards on the TLAN subnet. If a
Voice Gateway Media Card becomes the primary card (Leader)
during an election, it assigns itself the Node IP address.
•
If the node IP address is changed, this affects the
configuration of the Connect Server IP address in the DHCP
Server for the IP Phones.
•
If the IP Phones are using partial DHCP mode, manually
reconfigure the IP address of each IP Phone.
c. Embedded LAN (ELAN) gateway IP address: Enter the
Embedded LAN (ELAN) gateway IP address in dotted decimal
format. This is the IP address of the gateway of the subnet to
which the Voice Gateway Media Card belongs. This is the IP
address of the router interface on the ELAN subnet, if present.
If the subnet does not have a Embedded LAN gateway, enter
0.0.0.0.
•
When a Embedded LAN gateway is added to the ELAN
subnet, it must restrict access so that only authorized traffic
is permitted on the ELAN subnet.
•
The router must disable the BootP relay agent for the ELAN
network interface.
•
The router must block all broadcast and multicast traffic from
the ELAN subnet and enable only proper access (that is,
only authorized traffic and users coming through the ELAN
gateway).
d. Embedded LAN (ELAN) subnet mask: Enter the Embedded
LAN subnet mask address in dotted decimal format. This is the
subnet mask that is used along with the ELAN network interface
IP address to identify to which subnet the Voice Gateway Media
Card belongs. When changing these subnet masks, consider
the possibility of conflict between the ELAN and TLAN network
interface IP addresses. Consult with the network administrator
before making any changes to subnets.
