Information
The chassis MIB contain the entry chSysXfpRecvPower in the chSysPortTable table. 
Periodically, IFA polls the XFP power for each of the ports, and sends the values to 
IFM where it is cached. The default interval for the polling is 300 seconds (5 
minutes). Use this command to enable the polling and to configure the polling 
frequency.
