Command History Release 3.0(1) 3.1(2) Modification This command was introduced. Added the naming keyword. Usage Guidelines All software releases prior to Cisco SAN-OS Release 3.0(1) support Generation 1 hardware. Cisco SAN-OS Release 3.0(1) and later support Generation 2 hardware. You can combine Generation 1 and Generation 2 switching modules, with either Supervisor-1 modules or Supervisor-2 modules. However, combining switching modules and supervisor modules has the following limitations: • Supervisor-1 modules only support a maximum of 256 port indexes, regardless of type of switching modules. • Supervisor-2 modules support a maximum of 1024 port indexes when all switching modules in the chassis are Generation 2. • Supervisor-2 modules only support a maximum of 256 port indexes when both Generation 1 and Generation 2 switching modules are installed in the chassis. Note The Cisco MDS 9124 switch does not support the show port index-allocation startup command; however, it does support the show port index-allocation command. Note On a switch where the maximum number of port indexes is 256, any module that exceeds that limit does not power up. Examples The following example displays port index allocation information at startup on a Cisco MDS switch with only Generation 1 switching modules installed. switch# show port index-allocation startup OL-18089-01, Cisco MDS NX-OS Release 4.x Cisco MDS 9000 Family Command Reference 22-297
