I am currently testing some PVLAN configurations and so far almost everything matches what I am expecting to see.
The most confusing part of the testing is that when I connect a sniffer and run ICMP packets back and forth I can not find the VLAN tag anywhere. The packet matches what I would expect to see on a native VLAN, but the PVLANs I am testing with are 950-959.
Does anyone know why I would not see PVLAN packets with tagged vlan information?
Does anyone have an example of a PVLAN packet with a tagged vlan they wouldn't mind showing me?
Any information about this problem or about the formation of the packets for PVLAN will be most helpful.
Thank you in advance for your knowledge, time, and assistance.
We have used up to 2 laptops to test with and of course the 4 host switches as well.. The entire test bed is configured for a /24 network.
If we connect a laptop to switch1 on a community 953 host port and send a ICMP to the 3550(host) that is connected on the community 953 host port the sniffer shows a ICMP packet that is just a basic native vlan ICMP packet. i.e. no vlan tag.
This path takes them accross a isl trunk on switch 1 and then thru the 6509 accross to the recieving host.
