Q
4 – EVIC Configuration and Monitoring Features
Indicates whether the IOC is in use by the Host. A value of 1 indicates the Host GUID identified in the Last Host GUID column is utilizing this Virtual NIC. A value of 0 indicates that no host is utilizing this Virtual NIC.
❥Last Host Name
The name of the host that last used the IOC.
❥Remote Host Types
Identifies the type of remote IB host (e.g., VirtualNIC). This field is valid when the In Use field has a value of 1.
❥Last Host GUID
The GUID of the Channel Adapter of the last host that used the IOC. If the In Use field has a value of 1, this is the GUID of the host currently utilizing the Virtual NIC.
❥Last Host Instance
An index that the Host provides to the EVIC. This index is used by the EVIC in conjunction with the Last Host GUID and the IOC Number to determine whether the Virtual NIC currently exists in the Virtual NIC Information window. If the Virtual NIC does not exist, the EVIC adds the Virtual NIC to the table and assigns it a MAC address which has not been previously used by another host. If a virtual NIC does exist, the EVIC assigns the same MAC address it had previously used.
Since the maximum number of Virtual NICs supported by a EVIC is 128, the connection request from a host will be refused if the limit has been reached.
❥Date Last Used
If the IOC is currently in use, this field indicates the time at which it connected. If the IOC is not currently in use, this field indicates when the Host disconnected from the IOC
❥MTU
The maximum transmission unit. Valid only when the In Use field value is 1.
❥MAC
The default unicast address of the Virtual NIC.
❥IOC
An index into the IOC table.
❥Ethernet Port
Identifies which of the 2 EVIC Ethernet ports a Virtual NIC is utilizing to access the Ethernet network.
❥Control QP
The queue pair number that the control path is using.
