Hot Swapping CMM Modules
Hot swapping a CMM refers to the action of adding, removing, or replacing a CMM module while the
switch is operating. You are not required to enter a CLI command in order to hot swap CMM modules.
This function can be performed on the fly by simply removing the module from the switch chassis.
Hot Swap Requirements
Removing or Replacing CMMs
You must have CMM redundancy before removing or replacing a CMM. If the switch has only one CMM
installed and you attempt to hot swap the module, all switch management functions, as well as network
data flow, will be terminated.
Also, before removing or replacing the primary CMM in a redundant configuration, verify that the primary
and secondary CMM modules are synchronized. Otherwise, data flow and switch management functions
may be interrupted due to incorrect or outdated software when the secondary CMM takes over.
Refer to
“CMM Redundancy” on page 3-9
and the “Managing CMM Directory Content” chapter in the
Switch Management Guide
for detailed information.
Adding a Secondary CMM
A secondary (or
redundant
) CMM module can be added to the chassis at any time without disturbing the
operation 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
“Synchronizing the Primary and Secondary CMMs” on page 3-9
.
Note.
For detailed instructions on physically installing and removing CMM modules, refer to
“Installing
CMM and CFM Modules” on page 3-5
