Ingress Filtering
Hybrid ports allow for changing ingress filtering. Access and trunk ports always have ingress filtering enabled. If
ingress filtering is enabled, frames classified to a VLAN that the port is not a member of get discarded.

If ingress filtering is disabled, frames classified to a VLAN that the port is not a member of are accepted and
forwarded to the switch engine. However, the port will never transmit frames classified to VLANs that it is not a
member of.

CLI example
– set ingress filtering on the second Gigabit port:
# configure terminal
(config)# interface GigabitEthernet 1/2
(config-if)# switchport hybrid ?
acceptable-frame-type Set acceptable frame type on a port
allowed Set allowed VLAN characteristics
when interface is in hybrid mode
egress-tag Egress VLAN tagging configuration
ingress-filtering VLAN Ingress filter configuration
native Set native VLAN
port-type Set port type
(config-if)# switchport hybrid ingress-filtering
(config-if)# exit
(config)# exit
#
(config)# interface GigabitEthernet 1/2
(config-if)# switchport hybrid ?
acceptable-frame-type Set acceptable frame type on a port
allowed Set allowed VLAN characteristics
when interface is in hybrid mode
egress-tag Egress VLAN tagging configuration
ingress-filtering VLAN Ingress filter configuration
native Set native VLAN
port-type Set port type
(config-if)# switchport hybrid ingress-filtering
(config-if)# exit
(config)# exit

Tagged and Untagged
Both tagged and untagged frames are accepted.
Tagged Only
Only tagged frames are accepted on ingress. Untagged frames are discarded.
Untagged Only
