Monitoring Features

These are the monitoring features:
•
•
•
OL-13018-01
– IP ToS/DSCP and IEEE 802.1p CoS marking based on flow-based packet classification
(classification based on information in the MAC, IP, and TCP/UDP headers) for
high-performance quality of service at the network edge, allowing for differentiated service
levels for different types of network traffic and for prioritizing mission-critical traffic in the
network
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
Policing
Traffic-policing policies on the switch port for managing how much of the port bandwidth
–
should be allocated to a specific traffic flow
In Cisco IOS Release 12.2(25)SED and later, 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
– Out-of-profile markdown for packets that exceed bandwidth utilization limits
Ingress queueing and scheduling
– 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
Shaped round robin (SRR) as the scheduling service for specifying the rate at which packets are
–
sent to the internal ring (sharing is the only supported mode on ingress queues)
Egress queues and scheduling
– Four egress queues per port
WTD as the congestion-avoidance mechanism for managing the queue lengths and providing
–
drop precedences for different traffic classifications
– SRR as the scheduling service for specifying the rate at which packets are dequeued to the
egress interface (shaping or sharing is supported on egress queues). Shaped egress queues are
guaranteed but limited to using a share of port bandwidth. Shared egress queues are also
guaranteed a configured share of bandwidth, but can use more than the guarantee if other queues
become empty and do not use their share of the bandwidth.
Switch LEDs that provide port- and switch-level status
MAC address notification traps and RADIUS accounting for tracking users on a network by storing
the MAC addresses that the switch has learned or removed
Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any port or
VLAN
