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 Layer 2 unknown unicast, multicast, and bridged broadcast
traffic
