When changing the Embedded LAN (ELAN) network interface
IP address, this must be coordinated with the IP address on the
Call Server (Active ELNK) network interface. Changes must also
be coordinated with the following:
•
Embedded LAN gateway, and other IP devices on the ELAN
subnet
• any other devices on the ELAN subnet and customer
enterprise network subnet that need to communicate with
IP Line
• devices that are looking to receive SNMP traps
e. Voice LAN (TLAN) subnet mask: Enter the Voice LAN subnet
mask address in dotted decimal format. This is the subnet mask
that is used, along with the TLAN network interface IP address,
to identify the subnet to which the Voice Gateway Media Card
belongs. Coordinate with the Voice LAN gateway (router). When
changing the Voice LAN (TLAN) subnet mask, the change must
be coordinated with a change to the subnet mask of the Voice
LAN (TLAN) gateway (router) network interface.
Expand the Cards section and select the card to be changed.
Enter the Card Properties data for the Leader and Follower cards:
a. Role: There must be at least one card in the node. This card is
the Leader. Every IP Telephony node must have only one Leader.
All other cards function as Followers. This field is read-only.
b. Embedded LAN (ELAN) IP address: This is the ELAN network
interface IP address for the card. Element Manager and the
system use this address to communicate with the card.
If changing the Embedded LAN network interface IP address
of the Leader card, Telnet to the card and use the setLeader
command to make the same change (new Management IP
address) in the NVRAM of the Leader card.
The Leader card must be reset to resume communication with
the node.
Before resetting the Leader card, unplug all the other cards to
prevent any other card from becoming the Master. When the
Leader restarts, plug the cards back in. These other cards
receive their new configuration from Leader 0.
c. Embedded LAN (ELAN) MAC address: This is the motherboard
Ethernet address from the
