Cisco Catalyst Blade Switch 3130 for Dell Software Configuration Guide
OL-13270-01
Chapter1 Overview
Features
–
Provisioning a new member for a switch stack with the offline configuration fea ture . You can
configure in advance the interface configuration for a specific stack member number and for a
specific switch type of a new switch that is not part of the stack. The switch stack retains this
information across stack reloads whether or not the provisioned switch is part of the stack.
–
Displaying stack-ring activity statistics (the number of fr ames sen t by each stack member to the
ring).
Performance Features
The switch ships with these performance features:
•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 the maximum packet size or maximum transmission unit (MTU) size for these types of
frames:
–
Up to 9216 bytes for routed frames
–
Up to 9216 bytes for frames that are bridged in hardware and software through Gigabit Ethernet
ports and 10-Gigabit Ethernet ports
•IEEE 802.3x flow control on all ports (the switch does not send pause frames)
•Up to 64 Gb/s of throughput in a stacking-capable switch stack
•Up to 68 Gb/s of throughput on a nonstacking-capable switch
•EtherChannel for enhanced fault tolerance and for providin g up t o 8 Gb/s (Gigabit EtherChannel)
or 80 Gb/s (10-Gigabit EtherChannel) full-duplex bandwidth among switches, routers, a nd 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
•Forwarding of Layer 2 and Layer 3 packets at Gigabit line rate across the switches in the stack
•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 Gr oup Man agem ent
Protocol (IGMP) snooping for IGMP Versions 1, 2, and 3:
–
(For CGMP devices) CGMP for limiting multicast traffic to specifie d end stati ons a nd reducing
overall network traffic
–
(For IGMP devices) IGMP snooping for efficiently forwarding multimedia and multicast traf f ic
•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 pe riodic I GMP G ener al Qu er y
