Q

4 – EVIC Configuration and Monitoring Features

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.
