OL-13018-01
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. For a list of cluster-capable
switches, see the release notes.
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 and
10/100/1000 Mb/s interfaces and on 10/100/1000 BASE-TX SFP module interfaces that enables the
interface to automatically detect the required cable connection type (straight-through or crossover)
and to configure the connection appropriately
Support for up to 9000 bytes for frames that are bridged in hardware, and up to 2000 bytes for frames
that are bridged by software
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 Gb/s (Gigabit EtherChannel)
or 800 Mb/s (Fast EtherChannel) full-duplex bandwidth among switches, routers, and servers
Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for automatic
creation of EtherChannel links
Forwarding of 2 packets at Gigabit line rate
Per-port storm control for preventing broadcast, multicast, and unicast storms
Port blocking on forwarding unknown 2 unknown unicast, multicast, and bridged broadcast traffic
Internet Group Management Protocol (IGMP) snooping for IGMP Versions 1, 2, and 3 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)
IGMP snooping querier support to configure switch to generate periodic IGMP general query
messages
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
IGMP leave timer for configuring the leave latency for the network
Switch Database Management (SDM) templates for allocating system resources to maximize
support for user-selected features
