Q

the VLAN specified by the PVID value (which defaults to 1). The PVID of a port should between 1 and 4094.

Egress Rule

This is a filter on the forwarded packets on a per-port basis. The user can enable or disable the filter. If the Egress Rules field is enabled, the Egress Tagging field is enabled.

If Egress Rules are set to Disabled, a frame is sent out the external Ethernet port without a VLAN tag, or with a VLAN ID of 0 if a Priority value is to be included in the frame.

If the Egress Rules are set to Enabled, and the VLAN of a packet is in the VLAN Membership field of the Ethernet port, the frame is sent out the external Ethernet port. Otherwise the frame is discarded (i.e., not sent out the Ethernet port).When the Egress Rule is enabled, the user should typically include the PVID value in the VLAN Membership.

Egress Tagging

Indicates whether the outgoing packet should be tagged with the specified VLAN ID. The tagging is enabled only if the Egress Rule is Enabled. A user can add the port to a particular VLAN by specifying the VLAN ID in this field. Deleting a VLAN ID from this field removes the port from this VLAN. Multiple VLAN IDs should be specified as a space-separated list. The valid VLAN ID values are between 1 and 4094.

If the VLAN of a packet is listed in the Egress Tagging field for a specified external Ethernet port, the packet is sent with a VLAN tag.

If the VLAN of the packet is not listed in the Egress Tagging field for a specified external Ethernet Port, the packet is sent untagged. An exception to this would be if a host has specified a priority value, in which case the packet is sent with a VLAN tag but with a VLAN ID of 0.

The Egress Tagging field contains a list of space-separated VLAN IDs, which should be all the VLAN IDs for devices that understand VLAN tags reachable over a specified external Ethernet port.

Ingress Rule

Is a filter on the incoming packets (on a per-port basis). A user can enable or disable the filter. If the rule is enabled then the VLAN Membership and Ingress Frame Type fields are enabled.

If this is set to Disabled, no filtering is done based on the VLAN tag (or absence of a VLAN tag). Any packet received on the port is forwarded to the Egress Rules of the appropriate host port for possible filtering.
