Configure a Virtual Service

About this task

Perform this procedure to configure a virtual service on the switch.

Note

• Following procedure lists the general sequence to configure a virtual service.

• The names of Ethernet ports appearing in a specific Virtual Machine (VM) are not correlated to the configured virtual port names. Each VM renames the Ethernet ports as per its requirements, after they are discovered during the VM initialization.

• By default, all virtual ports of OVS connection type appear first in the alphabetical order of their configured names, followed by the virtual ports of SR-IOV and VT-d connection types.

1. Enter Global Configuration mode:

   enable

   configure terminal

2. Create a VLAN:
   

   Note

   Virtual service configuration supports port-based VLANs only.

   vlan create <2-4059> name WORD<0-64> type {port-mstprstp <0-63>} [color <0-32>]

3. Add the IAH and faceplate port to the VLAN:

   vlan members add <1-4059> {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

4. Enter GigabitEthernet Interface Configuration mode:

   interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

   

   Note

   If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

5. Enable the IAH and faceplate ports:

   no shutdown

6. Exit to Global Configuration mode:

   exit

7. Optional: Create a virtual service:

   virtual-service WORD<1-80>

8. Optional: Configure the number of CPU cores to be assigned to the virtual service created:

   virtual-service WORD<1-80> num-cores <1-6>

9. Optional: Configure the memory size to be assigned to the virtual service created:

   virtual-service WORD<1-80> mem-size <1-50000>

10. Optional: Configure the disk to be assigned to the virtual service created:

    virtual-service WORD<1-80> disk WORD<1-32> size <1-30>

11. Configure the virtual port connection type:
    

    Note

    Ensure the connection type you configure for the virtual port matches the connection type supported by the IAH port.

    virtual-service WORD<1-80> vport WORD<1-32> connect-type {ovs | sriov | vtd}

12. Configure the IAH port to associate with the connection type:

    virtual-service WORD<1-80> vport WORD<1-32> port WORD<1-32>

    

    Important

    You cannot configure two virtual services with conflicting connect types on the same IAH port. You cannot configure two virtual services with VT-d connect type on the same IAH port.

13. Configure the NIC type of the IAH port:

    virtual-service WORD<1-80> vport WORD<1-32> port WORD<1-32> nic-type {virtio | e1000}

14. Add the virtual port to the VLAN created:

    virtual-service WORD<1-80> vport WORD<1-32> vlan <1-4096>

15. Enable the virtual service:

    virtual-service WORD<1-80> enable

Example

Configuring the TPVM virtual service using IAH port 1/s1 with an SR-IOV connection type:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#interface GigabitEthernet 1/s1
Switch:1(config-if)#encapsulation dot1q
Switch:1(config-if)#exit
Switch:1(config)#vlan create 10 name tpvm-lan-vlan type port-mstprstp 0 
Switch:1(config)#vlan members add 10 1/s1,1/6/2
Switch:1(config)#interface GigabitEthernet 1/s1,1/6/2
Switch:1(config-if)#no shutdown 
Switch:1(config-if)#exit
Switch:1(config)#virtual-service tpvm vport eth0 connect-type sriov
Switch:1(config)#virtual-service tpvm vport eth0 vlan 10
Switch:1(config)#virtual-service tpvm enable

Configuring the TPVM virtual service on IAH port 1/s2 with a VT-d connection type:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#vlan create 10 type port-mstprstp 0 
Switch:1(config)#vlan member add 10 1/1,1/s2 
Switch:1(config)#interface GigabitEthernet 1/s2,1/1 
Switch:1(config-if)#no shutdown
Switch:1(config-if)#exit
Switch:1(config-if)virtual-service tpvm vport eth0 port 1/s2
Switch:1(config)#virtual-service tpvm enable
