z Internet Group Management Protocol (IGMP) snooping support to limit flooding of IP multicast traffic. z Multicast Virtual Local Area Network (VLAN) registration (MVR) to continuously send multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security. z IGMP filtering for controlling the set of multicast groups to which hosts on a switch port can belong. z Dynamic address learning for enhanced security. z Support for multiple EtherChannel load balance algorithms (SMAC or DMAC, SIP or DIP, XOR-SMAC/DMAC or XOR-SIP/DIP) to offer maximum performance on aggregated links. z Web Cache Communication Protocol (WCCP) for redirecting traffic to wide area application engines, for enabling content requests to be fulfilled locally, and for localizing Web traffic patterns in the network (supported by IP Services feature set only). z Manageability z Address Resolution Protocol (ARP) for identifying a switch through its IP address and its corresponding MAC address. z Cisco Discovery Protocol (CDP) Versions 1 and 2 to aid in troubleshooting and reporting on misconfiguration of ports connecting to other devices supporting CDP. z Link Layer Discovery Protocol (LLDP) and LLDP Media Endpoint Discovery (LLDP-MED) for interoperability with third-party IP phones. z Network Time Protocol (NTP) for providing a consistent time stamp to all switches from an external source. z Directed unicast requests to a Trivial File Transfer Protocol (TFTP) server for obtaining software upgrades from a TFTP server. z Default configuration storage in flash memory to ensure that the switch can be connected to a network and can forward traffic with minimal user intervention. z In-band monitoring of the switch through the built-in Cisco Device Manager Web-based tool. z In-band management access through up to 16 simultaneous Telnet connections for multiple command line interface (CLI)-based sessions over the network. z In-band management access through up to five simultaneous, encrypted Secure Shell (SSH) connections for multiple CLI-based sessions over the network. This option is available only in the cryptographic software image. z In-band management access through SNMP versions 1, 2c, and 3 get and set requests. z Out-of-band management (CLI) with switch module's console port. z Supported by CiscoWorks management software. z Protected Mode feature to isolate switch management from Advanced Management Module, for increased security of the switch. z Cisco Network Services (CNS) embedded agents for automating switch management, configuration store, and delivery. z Cisco Network Assistance (CNA), a free GUI-based application tool to configure most features of this switch. For more information and download of CNA, go to http://www.cisco.com/go/cna z Extensive debugging options to aid in troubleshooting and diagnosing issues. z Support for multiple management interfaces.
