CoS Mapping Table for Trusted Ports

Mapping is from the designated field values on trusted ports’ incoming packets to a traffic class priority (actually a CoS traffic queue). The trusted port field-to-traffic class configuration entries form the Mapping Table the switch uses to direct ingress packets from trusted ports to egress queues.

Egress Port Configuration—Traffic Shaping

For unit/slot/port interfaces, you can specify the shaping rate for the port (in Kbps), which is an upper limit of the transmission bandwidth used.

Queue configuration

For each queue, you can specify:

•Minimum bandwidth guarantee

•Scheduler type – strict/weighted: Strict priority scheduling gives an absolute priority, with highest priority queues always sent first, and lowest priority queues always sent last. Weighted scheduling requires a specification of priority for each queue relative to the other queues, based on their minimum bandwidth values.

Queue Management Type

The switch supports the tail drop method of queue management. This means that any packet forwarded to a full queue is dropped regardless of its importance.

CLI Examples

Figure 7-1 illustrates the network operation as it relates to CoS mapping and queue configuration.

Four packets arrive at the ingress port 1/g10 in the order A, B, C, and D. You’ve configured port 1/g10 to trust the 802.1p field of the packet, which serves to direct packets A, B, and D to their respective queues on the egress port. These three packets utilize port 1/g10’s 802.1p to COS Mapping Table. In this case, the 802.1p user priority 3 was set up to send the packet to queue 5 instead of the default queue 3. Since packet C does not contain a VLAN tag, the 802.1p user priority does not exist, so Port 1/g10 relies on its default port priority (2) to direct packet C to egress queue 1.
