debugging more than one VLAN on a C2950?

Hi, I have 4 vlans (1-4), Nr. 1 is the managements vlan. The trafic is going through all 4 vlans. When i start "debug ip packet" i only see the packets going through VLAN1. Why i don't see the packets going through VLAN3-4? How to debug all 4 vlans? Thank you! Vlado

Re: debugging more than one VLAN on a C2950?

2950 is not a router and all packets are switched in hardware except for cpu bound traffic. Vlan is for management only. the debug will not capture non-management user traffic being switched in hardware. Using debug ip packet to analyse packets is not a good idea. use other ways like sniffer or other means.

Thank you very much for THAT quick response, but i think you misunderstood me. I'm talking of course about a switch C2950. After starting "debug ip packet" i see all the IP's which are communicating in VLAN1. That's fine, i don't need to see anything else. But i also want to see the IP's in VLAN2, 3 and 4.
