Service Egress and Ingress QoS Policies
Quality of Service Guide 371
Template
Implies that this policy can be applied to multiple SAPs on the router.
Description A text string that helps identify the policy’s context in the configuration
file.
Default FC Specifies the default forwarding class for the policy.
Priority Specifies the enqueuing priority when a packet is marked with a dot1p-
value specified.
Criteria-type IP
Specifies that an IP criteria-based SAP ingress policy is used to select the
appropriate ingress queue and corresponding forwarding class for
matched traffic.
MAC
Specifies that a MAC criteria-based SAP is used to select the appropriate
ingress queue and corresponding forwarding class for matched traffic.
Mode Specifies the configured mode of the meter (trTcm or srTcm).
CIR Admin Specifies the administrative Committed Information Rate (CIR)
parameters for the queue. The CIR defines the rate at which the system
prioritizes the queue over other queues competing for the same
bandwidth.
CIR Oper The operational value derived by computing the CIR value from the
administrative CIR and PIR values and their corresponding adaptation
rules.
CIR Rule min
The operational CIR for the queue will be equal to or greater than the
administrative rate specified using the rate command.
max
The operational CIR for the queue will be equal to or less than the
administrative rate specified using the rate command.
closest
The operational PIR for the queue will be the rate closest to the rate
specified using the rate command without exceeding the operational PIR.
PIR Admin Specifies the administrative Peak Information Rate (PIR) parameters for
the queue. The PIR defines the maximum rate that the queue can transmit
packets through the switch fabric (for SAP ingress queues) or out an
egress interface (for SAP egress queues).
PIR Oper The administrative PIR specified by the user.
PIR Rule min
The operational PIR for the queue will be equal to or greater than the
administrative rate specified using the rate command.
max
The operational PIR for the queue will be equal to or less than the
administrative rate specified using the rate command.
