I have a problem that I though would be very easy to solve.
I have a Cisco 1721 that has a frame-relay T1 to the internet, and I have three vlans hanging of of fa0.
One vlan is for voice traffic and needs absolute priority to the internet. One vlan is for general office traffic and should have less priority than the voice vlan. One vlan is for public wireless access and should have the lowest priority.
I've fiddled with CBWFQ, LLQ and a few others. None of them seem to work with Frame - the command to apply the policy to the subinterface either doesn't exist or I get a line similar to: CBWFQ : Not supported on subinterfaces Applying to the main interface has no effect.
This should be pretty easy, what am I missing?
