Clustering switches conserves IP addresses if you have a limited number of them.
If you plan to create switch clusters, you must assign IP information to a
command switch. Through the command-switch IP address, you can manage and
monitor up to 16 switches.
When a switch joins a cluster, it is managed and communicates with other member
switches through the command-switch IP address. You can assign an IP address
to the candidate or member switch, but it is not necessary. When a member switch
has its own IP address, it remains manageable if it leaves the cluster and becomes
a standalone switch.
Changing the command-switch IP address ends your CMS session. Restart
your CMS session by entering the new IP address in the browser Location
field (Netscape Communicator) or Address field (Microsoft Internet
Explorer), as described in the release notes.
You can assign IP information by using the setup program (refer to the release
notes) or by manually assigning it (see the
page
6-2).
If you plan to create switch clusters, you should assign an enable secret password
to the command switch. You can assign a privilege level (1 to 15) to the password,
where level 15, the default, provides the highest level of security. An enable secret
password with privilege level 15 is required to access to the switch or switch
cluster through CMS and TACACS+ authentication. You can assign this password
by using the setup program (refer to the release notes) or by manually assigning
it (see the
"Changing the Password" section on page
It is not necessary to assign passwords to an individual switch if it will be a cluster
member. If a candidate switch has a password, you must enter that password to
add the switch to the cluster. When the switch joins the cluster, it inherits the
command-switch password and retains it when it leaves the cluster. If no
command-switch password is configured, the member switch inherits a null
password.
