10.0 CoS Classification
CAUTION: When Ingress and Egress CoS Supports are set to Enabled, modi-
fying either setting to Disabled may lead to temporary packet loss
and/or packet misordering.
When throughput exceeds the available bandwidth, Class of Service (CoS) are a set of
mechanisms that allows the 9145E to selectively drop service frames based on priority of the
packets serviced. From the CoS Configuration screen, you can enable or disable CoS support,
which includes Classification, Queuing, Scheduling and Queue Management functions, for the
9145E in the ingress or egress direction independently. The Ingress direction is from the User
Port into the Network (NET). The Egress direction is from the Network towards the User port.
From the Main Menu, select CoS Configuration (10) and press Enter. The Class of Service
Configuration screen (Figure 10-1) opens. From the Class of Service Configuration screen you
can modify classifier mapping, queue configuration, and congestion avoidance profiles for both
the ingress and egress paths independently.
