Restart a Voice Gateway Media Card
If the IP address of a single Voice Gateway Media Card has changed, it
must be restarted in order for the changes to take effect.

.
If entries must be made to the card routing table, click the Add
button to the right of Routes.
The Routes fields expand.
Enter the IP address and Subnet mask for any host that is not on
the ELAN subnet but requires access to the Voice Gateway Media
Card across the ELAN subnet.
A Telnet session for maintenance from a remote PC is an example of
when this would be needed. The address of the remote PC would
be added in the Route list.
The default route on the card causes packets for unknown subnets
to be sent out the TLAN network interface. Packets from an external
host arrive on the ELAN network interface. Responses are sent
on the TLAN network interface. This process can cause one-way
communication if the TLAN subnet is not routed to the ELAN subnet.
It is necessary to add an entry in the Route list to correct the routing
so that response packets are sent on the ELAN subnet. Each entry
creates a route entry in the card route table that directs packets out
the ELAN network interface. See
ELAN routes" (page
CAUTION
Use caution when assigning card routing table entries. Do
not include the IP address of an IP Phone. Otherwise,
voice traffic to these IP Phones is incorrectly routed
through the ELAN subnet and ELAN gateway. To avoid
including the wrong IP address, Nortel recommends that
Host IDs be defined for the card routing table entries.
To add additional routes, click the Add button again and enter the
route information. Repeat this step for each route to be added.
Click Save and Transfer and then click OK.
In the Node Configuration window, click the Transfer/Status button
associated with the node that had the IP address changes.
