Hi,
I have a couple of questions on VLAN config in cisco:
1)In cisco switches ,once a port is configured as VLAN Trunk will it accept or send untagged frames ?Is it that all frames are tagged(well, thats what i think) ?
2)If all frames are going to be tagged why do we require the TPID field in the IEEE802.1q frame format?All frames are tagged and hence is it not possible for the trunk port to interpret that the field following Source address is VLAN ID ?
thanks and regards,
prashant
