Q
NOTE:An EVIC contains both Ethernet and "virtual" ports. A virtual port is a
logical port going from the EVIC to an InfiniBand host. When a VirtualNIC host
connects to an IOC of the EVIC, the EVIC assigns a virtual port to the connection.
Port Range
A dropdown list where a user selects virtual ports (in 6-port increments).
Selecting one of the port ranges displays the information for those virtual ports.
Virtual Port
Displays the virtual port numbers selected in the Port Range dropdown list.
PVID
The Primary VLAN ID (PVID) of a port. For any frame(s) without a VLAN tag,
or with VLAN ID of 0 this column specifies which VLAN the frame(s) will be
associated with. By default, untagged packets or those with a VLAN ID of 0
(also known as priority tagged frames) are assigned the VLAN specified by
the PVID value (which defaults to 1). Packets from a host are untagged unless
the interface has been set up with a VLAN tag (e.g., through the use of the
Linux vconfig command). The PVID of a port must be 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.
In general, the Egress Rules should be Enabled only if the host interface has
been configured to be in a VLAN (e.g., through the use of the Linux vconfig
command).
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.
