Cisco SG500X-24P Switch.


Only admin tagged frames, discard untagged frames (ingress & egress)


Is the following configuration correct:

Port VLAN Mode: General
VLANs: 100T, 200T, 4095P
Ingress filtering enabled
Admit Tagged Only

Is there anything else that I should configure to discard untagged traffic?

No. P indicates untagged traffic will be placed on that VLAN. 4095 is usually the VLAN for discarded traffic.
