Q
If the Ingress Rules are set to Enabled, the VLAN Membership and Ingress
Frame Type values are checked before forwarding the frame to the Egress
Rules of the appropriate host port for possible filtering.
NOTE: A frame coming from a Linux host will have a VLAN tag only if the
host interface has been configured to send vlan tags (e.g., with a
'vconfig' command).
VLAN Membership
Indicates which VLANs a port is member of. A user can add or delete the port
to a particular VLAN by specifying the VLAN ID. Multiple VLAN IDs should
be specified as a space-separated list. A valid VLAN ID is between 1 and 4094.
When Ingress Filtering is enabled, the following rules apply. Tagged frames
received on the Ethernet port will be forwarded if the VLAN ID of the frame is
in the VLAN Membership list. Untagged and priority tagged frames received
on the Ethernet link will be forwarded if the PVID of the Ethernet port is in the
VLAN Membership list. Otherwise the frame is discarded.
Ingress Frame Type
The Ingress Frame Type is a rule controlling whether non-VLAN tagged
frames are accepted. When the Ingress Frame Type is set to Admit All, all
packets (both VLAN and non-VLAN tagged) are accepted. Otherwise, only
packets that arrived with an explicit VLAN tag are accepted.
Default Priority
Indicates the 802.1p-based priority of a packet if the incoming frame does not
contain a VLAN tag. The priority should be between 0 and 7.
Host Ignores VLAN
If set to Enabled (default), the host ignores the current VLAN configuration.
This field should be set to Disabled if the host is specifying a VLAN (e.g., the
vconfig command is used on the interface on a Linux host).
Host Name
For virtual ports that are currently connected, this field indicates the host name
associated with a specific virtual port.
IOC
The IOC number of the EVIC associated with a virtual port. In an
/etc/sysconfig/ics_inic.cfg file, each 'create' item defines a
virtual port. The IOC number for a particular virtual port comes from the
'create' block for the virtual port. The Host Instance value also comes from
the 'create' block for the virtual port. These fields are only valid for the
virtual ports in use.
