IP Routing
General DescriptionIP routes are needed when switches are connected in an IP network and default 
gateways are not assigned and you want network nodes on different (sub)networks to 
communicate. 
There are two type of IP routes — host and network. The following table summarizes 
when you would use each type:
In a LAN environment, if network security is a concern,...

Route NumberA number that identifies this IP route.
Destination NodeThe node name of the final destination for this connection. 
GatewayThe node name of the first intermediate node. 
C-LAN BoardThe slot location of the local C-LAN board.Valid Value Usage

MetricThe metric value indicates the desirability of the IP route in terms of the efficiency of 
the data transmission between two nodes. 
If there are two routes to the same destination, one with metric 0 and one with metric 
1, the switch software will choose the route with metric 0 because it is (if properly 
administered) the more efficient route of the two. On the other...

A message originating on Switch B destined for node 6 can use either route 2 or the 
implied route. The switch will choose the implied route because it has metric 0 while 
route 2 has metric 1. By using the implied route, the message goes directly from the 
source to C-LAN2, without passing through C-LAN1. If route 2 had been 
administered with metric 0, the switch may have...

IP Media Parameters 
This screen specifies the types of codecs available on the IP Interface board 
(TN802B). The codecs encode and compand the analog voice data for transmission 
over the IP facilities. The order in which the codecs are listed is the preferred order of 
use by the switch.
Note:The codec ordering must be the same on DEFINITY switches at both 
ends of an H.323...

Data Module Screens
The Data Module screen must be administered at both ends of a DCS connection, except for ISDN connections. 
There are two types of data modules used with TCP/IP connections — ppp and ethernet. There are two types of 
data modules used with BX.25 connections — the proc-intf data module is used for the csi and si models, and the 
x.25 data module is used with...

Node NameThe node name for the interface (C-LAN port) defined by this data module.
Destination NumberThis field specifies the destination of the link. 
Used to enable access to the correct trunk group at the far end of the connection. This 
is typically the trunk access code (TAC) plus the extension of data module on the far 
end. If you use just the extension, then you must...
