Sunfire B1600 manual Switchport native vlan

Command Usage

■Ingress filtering only affects tagged frames.

■If ingress filtering is disabled, the interface accepts any VLAN-tagged frame if the tag matches a VLAN known to the switch (except for VLANs explicitly forbidden on this port).

■If ingress filtering is enabled, incoming frames tagged for VLANs that do not include this ingress port in their member set are discarded.

■Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.

Example

The following example shows how to set the interface to port SNP1 and then enable ingress filtering:

Console(config)#interface ethernet SNP1

Console(config-if)#switchport ingress-filtering

Console(config-if)#
