[c-nsp] 28xx performance question

[Matthew Crocker]

Hrmm..

  Could I put 500 VLAN sub-interfaces on one of the GigE ports, put the 
other GigE port into my core switch and support 50mbps or so?  Minimal 
ACls on the vlan interfaces.  Nothing fancy just aggregating a large 
number of VLANs.  Do you know what the limit for the IDB is on a 2800 
series?  Do you know if VLANs are supported under CEF?
