Recovering from Stack Failure or Topology Change
When a link or unit in the stack fails, a trap message is sent and a failure event is
logged. The stack will be rebooted after any system failure or topology change. It
takes two to three minutes for the stack to reboot. Also note that powering down a
unit or inserting a new unit in the stack will cause the stack to reboot.
Resilient IP Interface for Management Access
The stack functions as one integral system for management and configuration
purposes. You can therefore manage the stack through any port in the VLAN that
has been assigned an IP address. The Master unit does not even have to include an
active port member in the VLAN interface used for management access. However, if
the unit to which you normally connect for management access fails, and there are
no active port members on the other units within this VLAN interface, then this IP
address will no longer be available. To retain a constant IP address for management
access across fail over events, you should include port members on several units
within the primary VLAN used for stack management.
Basic Configuration
Console Connection
The CLI program provides two different command levels — normal access level
(Normal Exec) and privileged access level (Privileged Exec). The commands
available at the Normal Exec level are a limited subset of those available at the
Privileged Exec level and allow you to only display information and use basic
utilities. To fully configure the switch parameters, you must access the CLI at the
Privileged Exec level.
Access to both CLI levels are controlled by user names and passwords. The switch
has a default user name and password for each level. To log into the CLI at the
Privileged Exec level using the default user name and password, perform these
steps:
1. To initiate your console connection, press <Enter>. The “User Access
Verification” procedure starts.
2. At the Username prompt, enter “admin.”
3. At the Password prompt, also enter “admin.” (The password characters are not
displayed on the console screen.)
4. The session is opened and the CLI displays the “Console#” prompt indicating
you have access at the Privileged Exec level.
