Cisco Nexus 1000V for VMware vSphere Interface Configuration Guide, Release 5.x 1 New and Changed Information New and Changed Information Table 1: New and Changed Features for the Cisco Nexus 1000V Interface Configuration Guide Feature Description Changed in Release Port channel vPC-HM The interface 4.2(1)SV2(1.1) level configuration mode does not support sub-group cdp and manual options for port-channel vPC-HM configuration. Where Documented Configuring Port Channels Sub-group cdp and manual options for port-channel vPC-HM configuration are supported on the port-profile level configuration. Backup subgroups You can 4.2(1)SV1(4a) assign up to seven backup subgroups when pinning the primary subgroup. Configuring Port Channels Port channel relative numbering The subgroup 4.2(1)SV1(4a) numbering begins at zero and is not tied to the vmnic number. Configuring Port Channels Network state tracking for vPC-HM Pinpoints link 4.2(1)SV1(4) failures on a port channel configured for vPC-HM. Configuring Port Channels Cisco Nexus 1000V for VMware vSphere Interface Configuration Guide, Release 5.x 2 New and Changed Information New and Changed Information Feature Description Changed in Release Where Documented VEM management of LACP You can 4.2(1)SV1(4) offload operation of the LACP protocol from the VSM to the VEMs. Configuring Port Channels LACP You can 4.2(1)SV1(4) enable the LACP port channel function by turning on the feature using the feature lacp command. Configuring Port Channels System Jumbo MTU The system 4.2(1)SV1(4) jumbo MTU value is fixed at 9000 and cannot be changed. Configuring Interface Parameters Interface MTU You can 4.2(1)SV1(4) configure an interface MTU between 1500 and 9000. Configuring Interface Parameters Mapping vEthernet interfaces vEthernet 4.2(1)SV1(4) to connected ports interfaces are now mapped to connected ports by MAC addresses as well as the DVPort number. Configuring Virtual Ethernet Interfaces Cisco Nexus 1000V for VMware vSphere Interface Configuration Guide, Release 5.x 3 New and Changed Information New and Changed Information Feature Description Changed in Release Global vEthernet interface controls You can 4.2(1)SV1(4) enable or disable the automatic vEthernet interface controls by deleting unused vEthernet interfaces, purging manual vEthernet configurations, and creating vEthernet interfaces. Configuring Virtual Ethernet Interfaces Configuration limits Configuration 4.0(4)SV1(2) limits for vEthernet interfaces, vEthernet trunks, and port profiles were added. Interface Configuration Limits Cisco Nexus 1000V for VMware vSphere Interface Configuration Guide, Release 5.x 4 Where Documented New and Changed Information New and Changed Information Feature Description Changed in Release show interface vethernet command The show 4.0(4)SV1(2) interface vethernet command now displays 5-minute input and output packet/bit rate statistics for the interfaces that you specify. The configuration example showing this command output was updated to reflect this change. Where Documented Configuring Virtual Ethernet Interfaces The show interface ethernet command output also provides these new statistics. vPC-Host Mode Support for manual creation of subgroups. 4.0(4)SV1(2) Configuring Port Channels Static Pinning Support for 4.0(4)SV1(2) attaching (or pinning) a vEthernet interface to a specific port channel subgroup.
