* this terminal session

The running configuration is updated when modules are installed. If you save the running configuration to the startup configuration (using the copy running-configstartup-configcommand), during reboot the switch powers up the same set of modules as before the reboot regardless of the sequence in which the modules initialize. You can use the show port index-allocation startup command to display the index allocation the switch uses at startup.

switch#		show port index-allocation startup
Startup		module	index distribution:
------------------------------------------------------							+
Slot Allowed					Alloted indices info
		range	Total			Index values
--------------				-------	------------------------------
1		-----		34	0-31,80-81
2		-----		32	32-63
3		-----		16	64-79		(Slot 1 shares 80-81)
4		-----		48	96-127,224-239
SUP	253-255			3	253-255

Note The output of the show port index-allocation startup command does not display anything in the Allowed range column because the command extracts the indices from the persistent storage service (PSS) and displaying an allowed range for startup indices is meaningless.

If a module fails to power up, you can use the show module slot recovery-stepscommand to display the reason.

For information on recovering a module powered-down because port indexes are not available, refer to the Cisco MDS 9000 Family Troubleshooting Guide.

Tip Whenever using mixed Generation 1 and Generation 2 modules, power up the Generation 1 modules first. During a reboot of the entire switch, the Generation 1 modules power up first (default behavior).
