How to Change the Default EVB Configuration

Language:

You must configure the vsi-mgrid and vsi-mgrid-enc properties only on the physical link. The other EVB-related properties, such as vsi-typeid and vsi-vers, must be configured on a VNIC.

Become an administrator.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

Create a VNIC by using the datalink properties mentioned in the profile database.

# dladm create-vnic -l datalink -p maxbw=maxbw-value,priority=priority-value VNIC

Set the encoding that is associated with the VSI Manager ID to none on the physical link because you are not using the default Oracle VSI Manager ID.
```
# dladm set-linkprop -p vsi-mgrid-enc=none datalink
```
Set the VSI Manager ID on the physical link with an IPv6 address.
```
# dladm set-linkprop -p vsi-mgrid=IPv6-address datalink
```

Set the VSI Type ID and VSI Version for the VNIC that you have created.

# dladm set-linkprop -p vsi-typeid=VSI-Type-ID,vsi-vers=VSI-Version VNIC

Verify the properties that are set for the VNIC.
```
# dladm show-linkprop VNIC
```

Example 4-1 Setting EVB-Related Datalink Properties

The following example shows how to set datalink properties that are related to EVB. This example uses a system with a profile that you can access by using an IPv6 address, IP1.

Assume that the VSI Manager ID, IP1 has the following profiles defined:

VSI Type ID: 2
VSI Version: 1
Datalink properties: maxbw=20, priority=5

Create a VNIC by using the datalink properties mentioned in the profile.
```
# dladm create-vnic -l net0 -p maxbw=20,priority=5 vnic1
```
Set the encoding that is associated with the VSI Manager ID to none on the physical link net0 because you are not using the default Oracle VSI Manager ID.
```
# dladm set-linkprop -p vsi-mgrid-enc=none net0
```
Set the VSI Manager ID on the physical link net0 with the IPv6 address IP1.
```
# dladm set-linkprop -p vsi-mgrid=IP1 net0
```

Set the VSI Type ID and VSI Version for vnic1.

# dladm set-linkprop -p vsi-typeid=2,vsi-vers=1 vnic1

Verify the properties that are set for vnic1.

# dladm show-linkprop vnic1
LINK     PROPERTY            PERM VALUE      EFFECTIVE  DEFAULT    POSSIBLE
...
vnic1    vsi-typeid          rw   2          2           --         --
vnic1    vsi-vers            rw   1          1           --         --
vnic1    vsi-mgrid           rw   IP1        IP1         --         --
vnic1    vsi-mgrid-enc       rw   --         none        oracle_v1  none,oracle_v1
...

The VDP ASSOC TLV unit for vnic1 contains the following information:

VSI Manager ID = IP1
VSI Type ID = 2
VSI Version = 1

Example 4-2 Displaying EVB-Related Datalink Properties on a Physical Link

The following example displays EVB-related properties on the physical link.

# dladm show-linkprop -p vsi-mgrid,vsi-mgrid-enc net4
LINK     PROPERTY            PERM VALUE        EFFECTIVE    DEFAULT      POSSIBLE
net4     vsi-mgrid           rw   --           --           ::           --
net4     vsi-mgrid-enc       rw   --           --           oracle_v1    none,oracle_v1

The output displays the default configuration of EVB in Oracle Solaris. By using the oracle_v1 encoding, the VSI Type ID and VSI version are automatically generated from the properties that are configured on the VNICs.

Example 4-3 Displaying EVB-Related Properties on a VNIC

The following example displays EVB-related properties on a VNIC.

# dladm show-linkprop vnic0
LINK     PROPERTY               PERM VALUE      EFFECTIVE  DEFAULT    POSSIBLE
...
vnic0    vsi-typeid             rw   --         94         --         --
vnic0    vsi-vers               rw   --         0          --         --
vnic0    vsi-mgrid              rw   --         ::         --         --
vnic0    vsi-mgrid-enc          rw   --         oracle_v1  oracle_v1  none,oracle_v1
...

The output displays the effective encoding for vnic0 as oracle_v1. In turn, the EFFECTIVE value for vsi-typeid 94 is automatically generated and effective for vnic0.
