ATM Configuration Guide Configuring Virtual Channels
8.2 CONFIGURING VIRTUAL CHANNELS
A virtual channel is a point-to-point connection that exists within a physical connection. You can create multiple virtual
channels within one physical connection, with each virtual channel having its own traffic profile.
The combination of VPI and VCI is known as the VPI/VCI pair, and identifies the virtual channel. Hence, if a VC is
configured with a certain VPI/VCI pair on one end of the physical link, the port at the other end must have the same
VPI/VCI pair to complete the connection.
Note Never use VCI numbers 0 through 31. These VCIs are used for signaling
purposes.
In the following example, a virtual channel on slot 5, port 1 is created with a VPI of 1 and a VCI of 100
After you configure a virtual channel you can apply traffic shaping and QoS parameters to manage the traffic on the
VC. For traffic shaping parameters, refer to "Traffic Shaping." For information on QoS, refer to "Traffic Management."
8.2.1 Gathering Traffic Statistics (OC-12)
Enabling traffic statistics allows you to gather and display various statistics about the virtual channel, including
“RMON-like” statistics, counts of frames sent and received, unicast/broadcast/multicast frames sent and received, etc
In the following example, traffic statistics are enabled on port 5.1.1.100
rs(config)# atm create vcl port at.5.1.1.100
rs(config)# atm set vcl port at.5.1.1.100 traffic-stats-enable
