Brocade FC Switch Optical signal strength view

Steps:
1. Run first, porterrshow view port status, then ' Statsclear ' and ' slotstatsclear '
2. View: Porterrshow, look at the port.
3. Collection of Supportshow, Supportsave
4. View Sfpshow-all can see the second-to-last line of 23 Rx power status, if larger is normal
Sfpshow-all:
