Information About Ingress Scheduling
proportional to its interface bandwidth. In Cisco IOS XE Release 3.1S, the SIP-10 scheduler, SIP-40
scheduler, and ESP scheduler ran in strict-priority mode. In this mode, if the high-priority queues of
either a participating SPA port or a participating SIP has data to send, these queues will be scheduled
first. The remaining bandwidth, if any, will then be shared among the low-priority buffers at a weight
that is proportional to the interface bandwidth or at a weight that is equal to the weight of all the SIPs.
The supported excess weight range from Cisco IOS XE Release 3.1S and onwards for intra-SIP
scheduling is as follows:
•
•
The supported minimum bandwidth range from Cisco IOS XE Release 3.1S and onwards for Inter-SIP
scheduling depends on the combination of SIP and ESP. Following is the range for minimum bandwidth
configuration for various combination of SIP and ESP:
•
•
•
The supported excess weight range for inter carrier card scheduling (ESP level) is as follows:
•
Configuring Intra-CC Scheduling
By default, ingress packets that are classified as high-priority by a SIP or SPA, are processed first, and
then sent. After processing the high-priority packets, the available excess bandwidth can be shared by
low-priority packets depending on the weight assigned to the interface or to the SPA. Execute the
following commands to configure the weight on an interface or for the entire SPA:
