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.
