The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

NLB has the following configuration guidelines and limitations:
You can configure Microsoft NLB in the interface configuration mode.
Note | Make sure that the Cisco Nexus 1000V is configured before you configure Microsoft NLB on Windows virtual machines (VMs). |
This example shows how to configure Microsoft NLB directly on vEthernet:
switch# configure terminal switch(config)# interface vethernet 1 switch(config-if)# no mac auto-static-learn switch(config-if)# show running-config interface vethernet 1 !Command: show running-config interface Vethernet1 !Time: Tue Nov 15 19:01:36 2011 version 4.2(1)SV1(5.1) interface Vethernet1 inherit port-profile vm59 description stc3, Network Adapter 2 no mac auto-static-learn vmware dvport 34 dvswitch uuid "ea 5c 3b 50 cd 00 9f 55-41 a3 2d 61 84 9e 0e c4" vmware vm mac 0050.56B3.0071 switch(config)#
This example shows how to unconfigure Microsoft NLB directly from a vEthernet interface:
switch# configure terminal switch(config)# interface vethernet 1 switch(config-if)# mac auto-static-learn switch(config-if)# show running-config interface vethernet 1 !Command: show running-config interface Vethernet1 !Time: Tue Nov 15 19:01:52 2011 version 4.2(1)SV1(5.1) interface Vethernet1 inherit port-profile vm59 description stc3, Network Adapter 2 mac auto-static-learn vmware dvport 34 dvswitch uuid "ea 5c 3b 50 cd 00 9f 55-41 a3 2d 61 84 9e 0e c4" vmware vm mac 0050.56B3.0071 switch(config)#
You can configure Microsoft NLB in the port profile configuration mode.
Note | Make sure that the Cisco Nexus 1000V is configured before you configure Microsoft NLB on Windows Virtual Machines (VMs). |
This example shows how to configure Microsoft NLB in port profile mode:
switch# configure terminal switch(config)# port-profile type vethernet ms-nlb switch(config-port-prof)# vmware port-group switch(config-port-prof)# switchport mode access switch(config-port-prof)# switchport access vlan 59 switch(config-port-prof)# no mac auto-static-learn switch(config-port-prof)# no shutdown switch(config-port-prof)# state enabled switch(config-port-prof)# show running-config port-profile ms-nlb !Command: show running-config port-profile ms-nlb !Time: Tue Nov 15 19:00:40 2011 version 4.2(1)SV1(5.1) port-profile type vethernet ms-nlb vmware port-group switchport mode access switchport access vlan 59 no mac auto-static-learn no shutdown state enabled switch(config-port-prof)#
This example shows how to unconfigure Microsoft NLB on a vEthernet interface in port profile mode:
switch# configure terminal switch(config)# port-profile type vethernet ms-nlb switch(config-port-prof)# mac auto-static-learn switch(config-port-prof)# show running-config port-profile ms-nlb !Command: show running-config port-profile ms-nlb !Time: Tue Nov 15 19:01:05 2011 version 4.2(1)SV1(5.1) port-profile type vethernet ms-nlb vmware port-group switchport mode access switchport access vlan 59 mac auto-static-learn no shutdown state enabled switch(config-port-prof)#
