Web Interface – Configuration
· Ingress acceptance of frames and configuration of egress tagging can be configured independently Port VLAN Set or show the port ’ s VLAN ID (a.k.a. PVID). Allowed VLANs are in the range 1 through 4095 (the default is 1. On ingress, frames get classified to the Port VLAN if:
The port is configured as VLAN “ Unaware ”
¾
The frame is untagged
¾
¾ VLAN awareness is enabled on the port, but the frame is priority tagged (VLAN ID = 0) On egress, frames classified to the Port VLAN do not get tagged if Egress Tagging configuration is set to “ Untag Port VLAN ” . The Port VLAN is called an “ Access VLAN ” for ports in Access mode and Native VLAN for ports in Trunk or Hybrid mode. Port Type Ports in hybrid mode allow for changing the port type, so that the frame ’ s VLAN tag can be used to classify the frame on ingress to a particular VLAN, and if so, which TPID it reacts on. Likewise, on egress, the Port Type determines the TPID of the tag, if a tag is required. There are four Port Types: Unaware: On ingress, all frames whether carrying a VLAN tag or not, get classified to the Port VLAN, and possible tags are not removed on egress. C-Port: On ingress, frames with a VLAN tag with TPID = 0x8100 get classified to the VLAN ID embedded in the tag. If a frame is untagged or priority tagged, the frame gets classified to the Port VLAN. If frames must be tagged on egress, they will be tagged with a C-tag. S-Port: On ingress, frames with a VLAN tag with TPID = 0x8100 or 0x88A8 get classified to the VLAN ID embedded in the tag. If a frame is untagged or priority tagged, the frame gets classified to the Port VLAN. If frames must be tagged on egress, they will be tagged with an S-tag. S-Custom-Port: On ingress, frames with a VLAN tag with a TPID = 0x8100 or equal to the Ethertype configured for Custom S-ports get classified to the VLAN ID embedded in the tag. If a frame is untagged or priority tagged, the frame gets classified to the Port VLAN. If frames must be tagged on egress, they will be tagged with the custom S-tag.
