Cisco Catalyst Blade Switch 3130 for Dell Software Configuration Guide
OL-13270-01
Chapter 1 Overview
Features
–
Provisioning a new member for a switch stack with the offline configuration feature. 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 frames sent 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 providing up to 8 Gb/s (Gigabit EtherChannel)
or 80 Gb/s (10-Gigabit 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 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 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)
• IGMP snooping querier support to configure switch to generate periodic IGMP General Query
messages
