QuickSpecs
Overview
PoE allocations: supports multiple methods (automatic, IEEE 802.3af class, LLDP-MED, or user-specified) to allocate PoE power
for more efficient energy savings
Voice VLAN: automatically assigns VLAN and priority for IP phones, simplifying network configuration and maintenance
IP multicast snooping (data-driven IGMP): prevents flooding of IP multicast traffic
Internet Group Management Protocol (IGMP): utilizes Any-Source Multicast (ASM) or Source-Specific Multicast (SSM) to manage
IPv4 multicast networks; supports IGMPv1, v2, and v3
Protocol Independent Multicast (PIM): defines modes of Internet multicasting to allow one-to-many and many-to-many
transmission of information; supports PIM Dense Mode (DM), Sparse Mode (SM), and Source-Specific Mode (SSM)
Multicast Source Discovery Protocol (MSDP): allows multiple PIM-SM domains to interoperate; is used for inter-domain
multicast applications
Multicast Border Gateway Protocol (MBGP): allows multicast traffic to be forwarded across BGP networks and kept separate
from unicast traffic
Multicast VLAN: allows multiple VLANs to receive the same IPv4 or IPv6 multicast traffic, lessening network bandwidth demand
by reducing or eliminating multiple streams to each VLAN
Device support
Cisco prestandard PoE support: detects and provides power to Cisco's prestandard PoE devices such as wireless LAN access
points and IP phones
Additional information
Green IT and power: use the latest advances in silicon development, shut off unused ports, and use variable-speed fans to
improve energy efficiency
Green initiative support: provides support for RoHS and WEEE regulations
