i have the following setup:
two switches 2960 connected together over a trunked connection (802.1q)
i have two vlans configured in the switch:
vlan 1 (default) and vlan2.
i have a sniffer connected and i am mirroring the port where the two switches are connected to the sniffer.
there is a router connected on a port - this port is an access-port in vlan 2.
if i do a ping from this router over the switch-switch connection, i am not able to see the vlanid in the packet?
the pingsize is only 100 byte
i need this investigation for analysing the cos fields in the vlan-header
thank - any idea ???
