About FICON Device Allegiance

FICON requires serialization of access among multiple mainframes, CLI, and SNMP sessions be 
maintained on Cisco MDS 9000 Family switches by controlling device allegiance for the currently 
executing session. Any other session is denied permission to perform configuration changes unless the 
required allegiance is available.
