Information About the Cisco EtherSwitch Service Modules

•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.

Power-over-Ethernet Features

•Ability to provide power to connected Cisco pre-standard and IEEE 802.3af-compliant powered devices from all 10/100-Mbps Ethernet ports if the Cisco EtherSwitch service module detects that there is no power up the circuit

•A 24-port PoE Cisco EtherSwitch service module can provide up to 15.4 W of power on each 10/100-Mbps port. A 48-port PoE Cisco EtherSwitch service module can provide up to 15.4 W of power to any 23 of the 48 10/100-Mbps ports. Any combination of ports can provide up to an average of 7.5 W of power at the same time, depending on the power supply capacity in the router chassis.

Note Total power provided is up to the limit of the platform power supply. PoE requires using the AC+IP power supply (not the default power supply) that was shipped with your router. For information about PoE power requirements, access the Cisco.com web page. Click the Products and Solutions link. From the pull-down menu, click Routers and Routing Systems. Click the router platform on which you will install the Cisco EtherSwitch service module.

Monitoring Features

•Cisco EtherSwitch service module LEDs that provide port-, service module-, and stack-level status

•MAC address notification traps and RADIUS accounting for tracking users on a network by storing the MAC addresses that the Cisco EtherSwitch service module has learned or removed

•Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any port or

VLAN

•SPAN and RSPAN support of Intrusion Detection Systems (IDS) to monitor, repel, and report network security violations

•Four groups (history, statistics, alarms, and events) of embedded RMON agents for network monitoring and traffic analysis

•Syslog facility for logging system messages about authentication or authorization errors, resource issues, and timeout events

•Layer 2 traceroute to identify the physical path that a packet takes from a source device to a destination device

•Time Domain Reflectometer (TDR) to diagnose and resolve cabling problems on copper Ethernet 10/100/1000-Mbps ports
