[c-nsp] Rate Limit On VLANs 3550

[Alex Foster]

Trying to configure rate-limiting per VLAN on a 3550 dot1q interface
(GigE port) - so that each VLAN using the trunk is allocated a
percentage of the bandwidth.

Can this be done ??  I have tried the following config. but it doesn't
appear to have any effect - any ideas what Im doing wrong.

  match vlan  100
