Description: This value must return the the total number of ports supported on the IOM. This value must be customized Note: When an IOM supports the ability to activate additional ports supported by the IOM hardware by installing a license key then this OID can be set in two different ways, such that the CMM firmware will handle displaying the port information correctly.

(1) The IOM firmware will account for both activated and un-activated ports due to the current installed license key and set the 'Total port available' equal to the activated ports only. (2) The IOM firmware does not differentiate and account for both activated and un-activated ports due to the current installed license key and set the 'Total port available' equal to the maximum supported ports by the IOM hardware.

In addition the OID 'portModuleLabel' for a non-activated port must be set to 'Unused' and the 'portModuleLicensedState' must be set to 'notLicensed'.

Although the CMM will handle either (1) or (2) above the IOM should implement (1) to assist the CMM user interface response time when displaying port information for the IOM. When an IOM implements (2) this will increase the CMM response time since this will require the CMM to issue more SNMP get operations for the various port information OID's and then discard the information for the user interface.
