HP(3Com) V1910 switch with 2 vlans: VLAN1 (native) and VLAN191
The Trunk Port is configured like this:
Why are frames tagged for '191' also being forwarded to VLAN1?
Any ideas.
Thanks

That port is set up to be a trunk. A trunk will carry both untagged (native) and tagged frames. You will forward both VLAN 1 (untagged) and VLAN 191 (tagged) frames on that port. If you want only VLAN 1 frames on the port, you need to set it to be an access port with only VLAN 1, or remove VLAN 191 membership from the trunk, instead of a trunk with both VLANs.
