Information About the Cisco EtherSwitch Service Modules

Cisco IOS Release 12.2(25)SEC

Ease-of-Use and Ease-of-Deployment Features

•Express Setup for quickly configuring a Cisco EtherSwitch service module for the first time with

basic IP information, contact information, Cisco EtherSwitch service module and Telnet passwords,

and Simple Network Management Protocol (SNMP) information through a browser-based program.

•Graphical user interfaces (GUIs) for easier Cisco EtherSwitch service module configuration and

monitoring. For more information about these GUIs, see the “Management Options” section on

page 6.

•User-defined and Cisco-default SmartPorts macros for creating custom Cisco EtherSwitch service

module configurations for simplified deployment across the network.

•Cisco StackWise technology for these uses:

–

Connecting up to nine Cisco EtherSwitch service modules through Cisco StackWise ports and

operating as a single switch in the network.

–

Using a single IP address and configuration file to manage the entire switch stack.

–

Automatic Cisco IOS software version-check of new stack members with the option to

automatically load images from the stack master or from a TFTP server.

–

Adding, removing, and replacing Cisco EtherSwitch service modules in the stack without

disrupting the operation of the stack.

–

Provisioning a new member for a switch stack with the offline configuration feature. You can

configure the interface configuration for a specific stack member number in advance. The

switch stack retains this information across stack reloads whether or not the provisioned

Cisco EtherSwitch service module is part of the stack.

–

Displaying stack-ring activity statistics (the number of frames sent by each stack member to the

ring).

Performance Features

•Autosensing of port speed and autonegotiation of duplex mode on all Cisco EtherSwitch service

module ports for optimizing bandwidth

•Automatic-medium-dependent interface crossover (Auto-MDIX) capability on 10/100-Mbps

interfaces that enables the interface to automatically detect the required cable connection type

(straight-through or crossover) and to configure the connection appropriately

•Up to 32 Gbps of forwarding rates in a switch stack

•EtherChannel for enhanced fault tolerance and for providing up to 800 Mbps (Fast EtherChannel)

of full-duplex bandwidth between Cisco EtherSwitch service modules, 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-per-second line rate across the

Cisco EtherSwitch service modules in the stack

•Per-port storm control for preventing broadcast, multicast, and unicast storms

•Port blocking on forwarding unknown Layer2 unknown unicast, multicast, and bridged broadcast

traffic
