Configuring System Information

ProSafe M5300 Switch

• Single IP address management through a web browser, the CLI, or SNMP.

• Master-slave configuration.

• The master retains configuration for entire stack.

• Automatic detection of new members, with synchronization of firmware (upgrade or

downgrade as needed).

• Configuration updates across the stack through a single operation.

• Automatic master fail-over. Fully resilient stack with chain and ring topology.

• Hot swapping (insertion and removal) of stack members.

Firmware Synchronization and Upgrade

All stack members must run the same software version to ensure compatibility within the

stack. By default, if a unit is added to the stack and its software version is not the same as the

stack master, that unit is not allowed to join the stack. You can enable the Stack Firmware

Auto Upgrade feature, which will automatically synchronize the firmware version on the new

unit with the version running on the stack master. The synchronization operation may result in

either upgrade or downgrade of firmware on the mismatched stack member.

Upgrading the firmware on a stack of switches is the same as upgrading the firmware on a

single switch. After you download a new image by using the File Download page or SCC, the

downloaded image is distributed to all the connected units of the stack.

Note: It is recommended to set the active image for all stack members the

same as the active image of the stack master. In other words, if

image1 is the active image on the stack master, all units should have

image1 as the active image. For information about configuring the

active image, see Dual Image Configuration on page 289.

Configuration Maintenance

The stack master stores and maintains the saved and running configuration files for the

switch stack. The configuration files include the system-level settings for the switch stack and

the interface-level settings for all stack members. Each stack member retains a copy of the

saved file for backup purposes. If the master is removed from the stack or becomes

unavailable, another member will be elected master, and will then run from that saved

configuration.

The switch master copies its running configuration to the stack member configured as the

standby unit whenever it changes (subject to some restrictions to reduce overhead). This

enables the standby unit to take over the stack operation with minimal interruption if the stack

master becomes unavailable. The running-config synchronization also occurs when the

running configuration is auto-saved on the stack master or when the standby unit changes.
