Adding a Secondary CMM
A secondary (or
redundant
) CMM can be added to the chassis at any time without disturbing the opera-
tion of the switch. However, you should synchronize the primary and secondary CMMs immediately after
the hot swap in order to have effective redundancy. For more information, refer to
Primary and Secondary CMMs” on page 3-10
Note.
For detailed instructions on physically installing and removing modules (both NIs and CMMs), refer
to
Chapter 5, “Network Interface (NI) Modules.”
Managing CMMs
Refer to the “Managing CMM Directory Content” chapter in the
Switch Management Guide
for detailed
information on managing CMMs.
Reloading a CMM
You can reload either the primary or secondary CMM using the CLI’s
command. For information
on using this command, refer to the “Managing CMM Directory Content” chapter in the
Switch Manage-
ment Guide
. A CMM reload is essentially a soft boot of the module. Note that you can reload only one
CMM at a time; the primary and secondary CMMs cannot be reloaded simultaneously.
Reloading the Primary CMM
If the primary CMM is reloaded, the secondary CMM automatically takes over primary management func-
tions. In other words, the secondary CMM becomes the primary CMM as soon as the reload is initiated.
The reloaded CMM then assumes the secondary—or
redundant
—role when the reload sequence is
complete.
Reloading the Secondary CMM
If the secondary CMM is reloaded, only the secondary CMM is affected. The primary CMM continues all
operations without interruption.
