Verifying Port Index Allocation Using Device Manager
To verify port index allocation using Device Manager, follow these steps:
Step 1 Choose Interfaces > Show Port Index Allocation > Current to display the allocation of port indexes
on the switch.
Module index distribution:
------------------------------------------------------+
Slot | Allowed | Alloted indices info |
| range | Total | Index values |
-----|---------|-------|------------------------------|
1 | 0- 255| 16 | 32-47 |
2 | 0- 255| 12 | 0-11 |
3 | 0- 255| - | (None) |
4 | 0- 255| - | (None) |
7 | 0- 255| - | (None) |
8 | 0- 255| - | (None) |
9 | 0- 255| - | (None) |
SUP | ----- | 3 | 253-255 |
In some cases, the sequence in which switching modules are inserted into the chassis determines if one
or more modules is powered up.

Symptom Possible Cause Solution
Module does not

Not enough port indexes are available. See the “Verifying Port Index Allocation Using Device
Manager” section on page 5-8 or the “Verifying Port Index
Allocation Using the CLI” section on page 5-9. If the
switch has Generation 1 modules inserted, upgrade to all
Generation 2 modules to gain higher total port index
availability.
Available port indexes are
non-contiguous.
See the “Verifying Port Index Allocation Using Device
Manager” section on page 5-8 or the “Verifying Port Index
Allocation Using the CLI” section on page 5-9.
Not enough power is available in the
chassis.
Use the show environment CLI command to determine if
you have enough available power for the module. Upgrade
your power supply, if necessary.
