ATM Sample Configuration 2
bandwidth connection, able to support video conferencing. Subnet B consists of users who require
less stringent requirements and are mainly concerned with email and server backup type of traffic.
As the network administrator, you can accommodate both client groups using only one ATM
physical connection. This is accomplished by setting up two VCs on the ATM port, each with its
own service profile definitions.
This example shows how to configure this network. The following sections will lead you through
the configuration process.
This will be done in two steps. The first step is to configure the network for traffic from Subnet A
and Subnet B to Subnet C. The second step is to configure the network for traffic from Subnet C to
Subnet A and Subnet B.
Note: Notice that there are two routers in this configuration example: XP1 and XP2. The
command line interface prompt will indicate whether the command is being inputted in
XP1 (xp1#) or XP2 (xp2#).
Traffic from Subnet A and Subnet B to Subnet C
Step 1: Configuring an Interface on Each Ethernet Port
The following command assigns an IP address of 10.1.1.130/24 on port et.2.4:
The following command assigns an IP address of 20.1.1.130/24 on port et.2.3:
The following command assigns an IP address of 50.1.1.130/24 on port et.5.1:
Step 2: Creating a Virtual Channel
The following command creates a virtual channel on port at.4.2 with VPI=0 and VCI=100:
The following command creates a virtual channel on port at.4.2 with VPI=0 and VCI=101:
xp1(config)# interface create ip subnetA address-netmask 10.1.1.130/24 port et.2.4
xp1(config)# interface create ip subnetB address-netmask 20.1.1.130/24 port et.2.3
xp2(config)# interface create ip subnetC address-netmask 50.1.1.130/24 port et.5.1
xp1(config)# atm create vcl port at.4.2.0.100
xp1(config)# atm create vcl port at.4.2.0.101
