You can also select
SSAP, Destination
MAC address, or
Source MAC
address as the
criteria.
Place all DLSw
traffic leaving
particular a
synchronous
interface in the
high priority
queue

This example
shows how to
prioritize DLSw
traffic before other
protocols on the
interface. To affect
the priority of
specific types of
DLSw traffic at the
TCP level, use
DLSw protocol
prioritization as
described in
Configuring DLSw
Services
.
