Hmm actually let me do that. Here is what i have right now on one of my 
interfaces:

### Interface 107 >> Descr: 'DataCenter 2MDF-SW1' | Name: '3/1' | Ip: '' | 
Eth: '00-0d-28-3f-8b-b8' ###

Interestingly enough when i do a show port 3/1 (this is the CatIOS Side, 
Hybrid Mode) i do not see any counters that would reflect that. show 
spantree 3/1 shows forwarding in all of the vlans but the graph at the 
momment display about

Max In  8753.5 kb/s (0.1%)   Average In  3592.3 kb/s (0.0%)   Current In  
4237.3 kb/s (0.1%)
Max Out  1520.6 kb/s (0.0%)   Average Out  1205.6 kb/s (0.0%)   Current Out  
1207.2 kb/s (0.0%)


is that correct? I mean seems awfully low so what i did was telneted to the 
other side and looked at the gigabit uplink. This is what i see for 5 
minutes

5 minute input rate 1238000 bits/sec, 933 packets/sec
  5 minute output rate 3966000 bits/sec, 978 packets/sec

Is there something i am missing maybe? or are these numbers accurate and 
that switch has little to no traffic maybe?

Mind you the biggest traffic generation is between the 2 cores and i've seen 
the max 50MB/s with the links being Gigabit.
