Applies to

  • Brocade Switches
  • FOS 8.2.1
  • MAPS
  • Cisco UCS FI

Issue

  • Starting from FOS 8.2.1, there is a MAPS feature which allows the switch to keep track of Cisco UCS FI ports and the number of NPIV devices logged in on each port. 
  • Additionally, this feature also allowed dynamic redistribution of NPIV logs across Cisco UCS FI uplinks. For more information on how re-balance feature works, watch this YouTube video from Brocade - Brocade FOS Automatically Rebalance UCS NPIV logins
  • With this issue, FOS fails to recognize Cisco UCS FI ports, which limits the functionality of NPIV re-balance feature by running command  devicelogin --rebalance

Example:

In this scenario, the number of initiators/NPIV is split across 4 ports, but only 2 ports are getting listed in the devicelogin --show

  • In the switchshow output, NPIV devices listed as expected.
