Equal-cost routing for load balancing and redundancy
Internet Control Message Protocol (ICMP) and ICMP Router Discovery Protocol (IRDP) for using
router advertisement and router solicitation messages to discover the addresses of routers on directly
attached subnets
Protocol-Independent Multicast (PIM) for multicast routing within the network, allowing for
devices in the network to receive the multicast feed requested and for switches not participating in
the multicast to be pruned. Includes support for PIM sparse mode (PIM-SM), PIM dense mode
(PIM-DM), and PIM sparse-dense mode. (requires the EMI)
Multicast Source Discovery Protocol (MSDP) for connecting multiple PIM-SM domains (requires
the EMI)
Distance Vector Multicast Routing Protocol (DVMRP) tunnelling for interconnecting two
multicast-enabled networks across non-multicast networks (requires the EMI)
DHCP relay for forwarding UDP broadcasts, including IP address requests, from DHCP clients
Ability to provide power to connected Cisco pre-standard and IEEE 802.3af-compliant powered
devices from all 10/100 Ethernet ports if the switch detects that there is no power on the circuit
24-port PoE switch provides 15.4 W of power on each 10/100 port; 48-port PoE switch provides
15.4 W of power to any 24 of the 48 10/100 ports, or any combination of ports provide an average
of 7.7 W of power at the same time, up to a maximum switch power output of 370 W
Automatic detection and power budgeting; the switch maintains a power budget, monitors and tracks
requests for power, and grants power only when it is available
Switch LEDs that provide port-, switch-, and stack-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
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 time-out events
Layer 2 traceroute to identify the physical path that a packet takes from a source device to a
destination device
Time Domain Reflector (TDR) to diagnose and resolve cabling problems on copper Ethernet
10/100/1000 ports
SFP diagnostic management interface to monitor physical or operational status of an SFP module.
