Are Port based VLAN devices designed to work with tag based VLANs ?
Yes.
normally port based vlans are for switch based ports linked to individual
end devices.
Tagged portsused to connect devices which handle multiple VLANs - often
other switches
I
am trying to figure out if I can use an AP which supports tag based
VLANs with a port based VLAN. All documents I found though the web were
implementations and not specs. I have a few basic questions:
If I have switch with the following Port based VLAN configuration:
Ports | VLAN ID
1,5 1
2,5 2
3,5 3
4,5 4
- Then an host on port 1 can only communicate with port 5 ? and port 2
with port 5 and so on ?
without know the device involved then you are basically asking for educated
guesswork - worth every penny you are paying for it.....
- Should the switch be inserting the appropriate vlan tag on the
outgoing frame on port 5 ? Eg: a VLAN tag of 1 on a packet from port 1
to port 5.
Depends on the switch implementation - there is no reason that
"membership of multiple internal vlans" must map to
"tag the packets with the internal vlans on this port"
- but it may do.
you may need to set the port into "tag" mode explicitly.
- Should the switch be expecting a VLAN tag on any inbound frame on
port 5 ?
If the port is set for vlan tagging, then it should use it for both inbound
and outbound packets.

Any information would be appreciated.
