Switch clustering technology for
– Unified configuration, monitoring, authentication, and software upgrade of multiple,
cluster-capable switches, regardless of their geographic proximity and interconnection media,
including Ethernet, Fast Ethernet, Fast EtherChannel, small form-factor pluggable (SFP)
modules, Gigabit Ethernet, and Gigabit EtherChannel connections. Refer to the release notes
for a list of cluster-capable switches.
Automatic discovery of candidate switches and creation of clusters of up to 16 switches that can
–
be managed through a single IP address.
Extended discovery of cluster candidates that are not directly connected to the command switch.
–
Autosensing of port speed and autonegotiation of duplex mode on all switch ports for optimizing
bandwidth
Automatic-medium-dependent interface crossover (Auto-MDIX) capability on 10/100 Mbps
interfaces and on 10/100/1000 BASE-T/TX SFP interfaces that enables the interface to
automatically detect the required cable connection type (straight-through or crossover) and to
configure the connection appropriately
IEEE 802.3X flow control on all ports (the switch does not send pause frames)
EtherChannel for enhanced fault tolerance and for providing up to 8 Gbps (Gigabit EtherChannel)
or 800 Mbps (Fast EtherChannel) full duplex of bandwidth between switches, routers, and servers
Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for automatic
creation of EtherChannel links
Forwarding of Layer 2 and Layer 3 packets at Gigabit line rate
Per-port storm control for preventing broadcast, multicast, and unicast storms
Port blocking on forwarding unknown Layer 2 unknown unicast, multicast, and bridged broadcast
traffic
Cisco Group Management Protocol (CGMP) server support and Internet Group Management
Protocol (IGMP) snooping for IGMP versions 1, 2, and 3:
– (For CGMP devices) CGMP for limiting multicast traffic to specified end stations and reducing
overall network traffic
– (For IGMP devices) IGMP snooping for efficiently forwarding multimedia and multicast traffic
IGMP report suppression for sending only one IGMP report per multicast router query to the
multicast devices (supported only for IGMPv1 or IGMPv2 queries)
Multicast VLAN registration (MVR) to continuously send multicast streams in a multicast VLAN
while isolating the streams from subscriber VLANs for bandwidth and security reasons
IGMP filtering for controlling the set of multicast groups to which hosts on a switch port can belong
IGMP throttling for configuring the action when the maximum number of entries is in the IGMP
forwarding table
Switch Database Management (SDM) templates for allocating system resources to maximize
support for user-selected features
