[c-nsp] Cisco 4500 not showing all the log detail?

[William]

Hi,

I have a Cisco 4500 running 12.1 IOS code.

It would seem we are not getting up/down port events in the log
buffer, to setup logging we have:

logging source-interface Vlan1
logging 192.168.1.1

we did set the logging buffer to informational (this doesnt show in
show run for some reason?), this is confirmed in 'sh logging' but we
aren't seeing the information we would expect!

Is there something I've missed? I am getting messages on counters
being cleared and configuration from console but that seems to be it.

Cheers,

W
