Catalyst 2960 and 2960-S Switches Software Configuration Guide, Release 15.0(1)SE

To use flow-based packet classification, the switch must be running the LAN Base image.

Trusted port states (CoS, DSCP, and IP precedence) within a QoS domain and with a port

bordering another QoS domain

Trusted boundary for detecting the presence of a Cisco IP Phone, trusting the CoS value

received, and ensuring port security

To use trusted boundary, the switch must be running the LAN Base image.

To use policy maps, the switch must be running the LAN Base image

Traffic-policing policies on the switch port for managing how much of the port bandwidth

should be allocated to a specific traffic flow

If you configure multiple class maps for a hierarchical policy map, each class map can be

associated with its own port-level (second-level) policy map. Each second-level policy map can

have a different policer.

Aggregate policing for policing traffic flows in aggregate to restrict specific applications or

traffic flows to metered, predefined rates

Out-of-profile markdown for packets that exceed bandwidth utilization limits

Two configurable ingress queues for user traffic (one queue can be the priority queue)

Weighted tail drop (WTD) as the congestion-avoidance mechanism for managing the queue

lengths and providing drop precedences for different traffic classifications

To use WTD, the switch must be running the LAN Base image.

Shaped round robin (SRR) as the scheduling service for specifying the rate at which packets are

sent to the stack ring (sharing is the only supported mode on ingress queues)

To use ingress queueing, the Catalyst 2960 switch must be running the LAN Base image.

Ingress queueing is not supported on Catalyst 2960-S switches.

Four egress queues per port

WTD as the congestion-avoidance mechanism for managing the queue lengths and providing

drop precedences for different traffic classifications
