ATM Sample Configuration 3
The following command applies the IP policy ‘subnetCtoBpolicy’ to port et.5.1:
All traffic between SubnetA and Subnet C will now travel over the 20 mbit VCL. Traffic between
Subnet B and Subnet C will travel over the 100 mbit VCL.
ATM Sample Configuration 3
Consider the following network configuration:
Suppose you are a network administrator in charge of managing a network with two client groups,
VLAN A and VLAN B. These two client groups have very different needs and requirements for
their users. VLAN A consists of users who need access to a high bandwidth connection able to
support video conferencing. VLAN B consists of users who require less bandwidth and are mainly
concerned with email and server backup traffic.
This network configuration is similar to the previous ATM Configuration, ATM Sample
Configuration 2 on page 108. However, the use of bridging and VLANs will provide the solution to
your networking requirements.
You as the network administrator can accommodate their different requirements using only one
ATM port. The following steps will lead you through the configuration process.
Configure an Interface on an Ethernet Port
There are two separate VLANs in this network, VLAN A and VLAN B. VLAN A is connected to
ethernet port et.5.1, and VLAN B is connected to ethernet port et.6.2.
