Here is the scenario. 6509 core, lots of 3750 stacks, 2- 4948-10GE. Router connects to 4948.
Multiple VLANs with inter VLAN routing.
I have NO access to Router. Need to stop a group of VLAN's from communicating to/from the outside world.
Network reconfiguration in progress, but need a quick, down and dirty method to accomplish this.
Can I block these at the port on the 4948 that the router is connected to?
