PVC Dialog Box—Protocol Tab
Use the Protocol tab of the PVC dialog box to add, edit, or delete the protocol mappings configured for
the PVC. You may configured static mappings or Inverse ARP (broadcast or nonbroadcast) for each
PVC, but not both.
Note IP is the only protocol supported by Security Manager for protocol mapping on ATM networks. You
cannot define protocol mappings on the Management PVC (ILMI).

VBR-RT The following fields are displayed when VBR-RT is selected as the Bit
Rate:
•Peak Rate—The peak information rate for realtime traffic in
kilobits per second (kbps).
•Average Rate—The average information rate for realtime traffic in
kilobits per second (kbps). This value must be lower than or equal
to the peak rate.
•Burst—The burst size for realtime traffic, in number of cells.
Configure this value if the PVC carries bursty traffic.
These values configure traffic shaping between realtime traffic (such as
voice and video) and data traffic to ensure that the carrier does not
discard realtime traffic, for example, voice calls.
IP QoS settings
Random Detect When selected, enables Weighted Random Early Detection (WRED) or
VIP-distributed WRED (DWRED) on the PVC.
When deselected, WRED and DWRED are disabled. This is the default.
WRED is a queue management method that selectively drops packets
as the interface becomes congested. See Tail Drop vs. WRED,
page 63-4.
