The endless VLAN headaches (and questions), eh?
I really have no idea how to title this one, do not judge.
I'm currently configuring VLANs on a Dell PowerConnect 2724 switch. Currently, all ports except 5 use PVID 1, no ingress filtering, admit all frames. Port 5 uses PVID 2. Ports 1 and 4 are tagged VLAN 2, and because PVID, untagged VLAN 1.
Visual representation (brackets = untagged / PVID):
1:  2 <-- gateway
4:  2 <-- me
5:  <-- other host
When I set port 5's "Frame Type" from
Admit All to
Admit Tag Only, then I (port 4) can send and receive packets from the gateway (port 1), but cannot receive any packets from any other machines on the network (port 5). I should be sending tagged as VLAN 2 packets anyways, so the description of
Admit Tag Only should allow it?
Admit All: "Tagged and untagged packets are accepted by the interface."
Admit Tag Only: "Only tagged packets are accepted by the interface."
I'm kinda confused here, partially because.. VLAN, and partially because Dell equipment apparently doesn't have meaningful help and manuals.
