You have a wedged interface see the URL below,
and yes if its wedged you would have problems
with moving traffic into the interface.

Subject: [nsp] Buffers full on switch?
Importance: High

Hi,
I have a problem with 2 x 2900XL not being able to resolve arps on it's VLAN
interface we use for management.

All the inbound packets are ignored by the VLAN interface, no errors occur.

Could this be due to full buffers?

I have found the following from going through my debugging process:

CPU9 buffers, 1524 bytes (total 110, permanent 110):
     0 in free list (0 min, 110 max allowed)
     22260939 hits, 2334313 misses

This is found by issuing the show buffers command. The output is similar on
the 2 switches only the cpu number is different.

I did a comparison on another switch and found it's buffers looked like
this:
        
CPU12 buffers, 1524 bytes (total 110, permanent 110):
     53 in free list (0 min, 110 max allowed)
     96606113 hits, 1293923 misses

As you can see it has 53 free buffers.

What I need to know is would this cause the VLAN interface to drop
everything that was input to it?

Thanks..
