Input Output Aggregator Module

You can view details of the IOM and Flex Modules on the CMC RACADM, and Chassis Health, I/O Module Status, and I/O Module Overview pages.

CMC reports information about the flex modules in the IOA by reading the flex module information during its initial negotiation with the IOA. The reading happens by sending XML commands during the initial negotiation. CMC saves the flex module information in the shared memory. There can be a maximum of two flex modules:
  • FlexIO Module 1
  • FlexIO Module 2
All IOM software that support the command revision 4 support the Flex IO module information XML command. CMC sends the flex module information only if the command revision is 4 or later. Any failure to read the flex module information is stored in the Chassis Log.
The flex module information can have the following five values:
  • 4x10G Base-T FlexIO Module = 0
  • 4x10G SFP+ FlexIO Module = 1
  • 2x40G QSFP+ FlexIO Module = 2
  • 4xFC FlexIO Module = 3
  • No flex module installed = 4

Any value greater than 4 is considered invalid. CMC displays as “Invalid/Unknown” flex module.

The modes of the IOM are as follows:
  • Standalone
  • VLT
  • Stacking
  • PMux
  • Full Switch

You can view the IOM mode as a tool tip when you select IOM on the Chassis Health, I/O Module Status, and I/O Module Overview pages.

While changing the mode of an IOA that has a static IP, from stacking to standalone, ensure that the network for the IOA is changed to DHCP. Else, the static IP is duplicated on all the IOAs.

When the IOMs are in stacking mode, the stack ID is the same as the master IOM burned in the MAC during the initial power-on. The stack ID does not change when the IOM modes change. For example, during initial power-on, if switch-1 is the master, the mac address of the stack is identical to that of the switch-1 burned in the MAC address. Later, when switch-3 is the master, the switch-1 MAC address is retained as the stack ID.

The racadm command, getmacaddress, displays I/F MAC, which is burned in MAC address + 2.
