Cisco Catalyst Blade Switch 3120 for HP Software Configuration Guide

Chapter 1 Overview
Features
– Interactive guide mode that guides you in configuring complex features such as VLANs, ACLs,
and quality of service (QoS).
– Configuration wizards that prompt you to provide only the minimum required information to
configure complex features such as QoS priorities for video traffic, priority levels for data
applications, and security.
– Downloading an image to a switch.
– Applying actions to multiple ports and multiple switches at the same time, such as VLAN and
QoS settings, inventory and statistic reports, link- and switch-level monitoring and
troubleshooting, and multiple switch software upgrades.
– Viewing a topology of interconnected devices to identify existing switch clusters and eligible
switches that can join a cluster and to identify link information between switches.
– Monitoring real-time status of a switch or multiple switches from the LEDs on the front-panel
images. The system and port LED colors on the images are similar to those used on the physical
LEDs.
• Cisco StackWise Plus technology for
– Connecting up to nine switches through their StackWise Plus ports that operate as a single
switch or switch-router in the network.
– Creating a bidirectional 32-Gb/s switching fabric across the switch stack, with all stack
members having full access to the system bandwidth.
– Using a single IP address and configuration file to manage the entire switch stack.
– Automatic Cisco IOS 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 switches 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 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
