Introduction

The Cisco Nexus 1000V provides a distributed, Layer 2 virtual switch that extends across many virtualized hosts. The Cisco Nexus 1000V manages a data center defined by the vCenter Server. Each server in the data center is represented as a line card in the Cisco Nexus 1000V and can be managed as if it were a line card in a physical Cisco switch.

The Cisco Nexus 1000V consists of the following two components:

Virtual Supervisor Module (VSM), which contains the Cisco CLI, configuration, and high-level features.

Virtual Ethernet Module (VEM), which acts as a line card and runs in each virtualized server to handle packet forwarding and other localized functions.

Software Compatibility

This section includes the following topics:

Software Compatibility with VMware

Software Compatibility with Cisco Nexus 1000

Software Compatibility with VMware

The servers that run the Cisco Nexus 1000 VSM and VEM must be in the VMware Hardware Compatibility list. This release of the Cisco Nexus 1000V supports vSphere 4.1.0 and 5.0.0 release trains.

Support for vSphere 4.0.0 is discontinued in this release of the Cisco Nexus 1000V. For additional compatibility information, see the Cisco Nexus 1000V Compatibility Information, Release 4.2(1)SV1(5.1).


Note All virtual machine network adapter types that VMware vSphere supports are supported with the Cisco Nexus 1000. Refer to the VMware documentation when choosing a network adapter. For more information, see the VMware Knowledge Base article #1001805.


Software Compatibility with Cisco Nexus 1000

This release supports hitless upgrades from Release 4.0(4)SV1(3a) and later releases. Upgrades are supported from 4.0(4)SV1(3) and earlier releases. For additional information, see the Cisco Nexus 1000V Software Upgrade Guide, Release 4.2(1)SV1(5.1).

Installer Enhancements

VXLAN

Microsoft Network Load Balancing

Redundant Routing Protocols

ACL Logging

Full Integration with vCloud Director

Cisco Nexus 1000V Support, vCloud Director, vShield Manager Support Matrix

Installer Enhancements

The Cisco Nexus1000V Installation Management Center is now a standalone Java application that can install the Cisco Nexus1000V VSM or VEM.

The Cisco Nexus1000V Installation Management Center supports a single flow for installing the Cisco Nexus1000V VSM in an HA pair, and can migrate the host on which it was deployed as a module.

For more information, see the Cisco Nexus 1000V Installation and Upgrade Guide, Release 4.2(1)SV1(5.1).

VXLAN

A Virtual Extensible Local Area Network (VXLAN) is a new LAN segmentation technology that enables scalable network isolation in the cloud. In a VXLAN, an entire Layer 2 frame is encapsulated in UDP, and a 24-bit VXLAN identifier is included. A VXLAN offers the following advantages:

Support for 16 million logical networks

Ability to cross Layer 3

Tunneling between VEMs

Virtualized network services with vPath 1.5

In addition, the VXLAN has been submitted to the IETF for standardization.

For more information, see the Cisco Nexus 1000V VXLAN Configuration Guide, Release 4.2(1)SV1(5.1).

Microsoft Network Load Balancing

Microsoft Network Load Balancing (NLB) is a clustering technology offered by Microsoft as part of the Windows server operating systems. Clustering enables a group of independent servers to be managed as a single system for higher availability, easier manageability, and greater scalability.

You can configure virtual Ethernet interface (vEths) to run Microsoft NLB in (default) unicast mode. You must configure the Cisco Nexus 1000V before you configure Microsoft NLB on Windows virtual machines (VMs). Microsoft NLB in unicast mode is the only mode currently supported, multicast mode and IGMP multicast mode is not supported on the Cisco Nexus 1000V.

For more information, see the Cisco Nexus 1000VLayer 2 Switching Configuration Guide, Release 4.2(1)SV1(5.1).

Redundant Routing Protocols

In Cisco Nexus 1000V Release 4.2(1)SV1(5.1), you can configure a virtual Ethernet interface and port profile to support the following redundant routing protocols:

VRRP (Virtual Router Redundancy Protocol)

CARP (Common Address Redundancy Protocol)

HSRP (Hot Standby Router Protocol)

User-defined custom routing protocols (identified by control packet header fields)

For more information, see the Cisco Nexus 1000VLayer 2 Switching Configuration Guide, Release 4.2(1)SV1(5.1).

ACL Logging

The ACL Logging feature allow users to monitor flows that hit specific ACLs. The ACLs can be configured with the optional log keyword in each of the ACEs. When the option is configured, statistics for each flow that matches the permit or deny conditions of the ACL entry are logged in software. You can also choose to log entries that matches the implicit deny rule of the ACL.

Full Integration with vCloud Director

The Cisco Nexus 1000V is fully integrated with VMware vCloud Director 1.5.1. The vCloud Director provides an abstraction layer that enables cloud service providers to provide an infrastructure as a service (IaaS) to various tenant organizations. vCloud Director also allows the tenant organizations to manage resources such as virtual data centers (vdcs), vApps, networks, and network pools.

The Cisco Network Segmentation Manager (NSM) feature of Cisco Nexus 1000V enables integration with VMware's vCloud Director and supports the following type of Network Pools:

Port-group backed pools

VLAN backed pools

Network isolation backed pools (via the VXLAN)

For more information, see the Cisco Nexus 1000V Network Segmentation Manager Configuration Guide, Release 4.2(1) SV1(5.1).

Cisco Nexus 1000V Support, vCloud Director, vShield Manager Support Matrix

The first Cisco Nexus 1000V release that works with vCloud Director 1.5.1 and vShield Manager 5.0.1 to support three types of networks is Cisco NX-OS Release 4.2(1)SV1(5.1a) which will be released in Q2 CY 2012. More details will be provided in the Release notes of Release 4.2(1)SV1(5.1a).

Single VMware Data Center Support

The Cisco Nexus 1000V can be connected to a single VMware vCenter Server datacenter object. Note that this virtual datacenter can span across multiple physical data centers.

vMotion of VSM

vMotion of the VSM has the following limitations and restrictions:

vMotion of a VSM is supported for both the active and standby VSM VMs. For high availability, we recommend that the active VSM and standby VSM reside on separate hosts.

If you enable Distributed Resource Scheduler (DRS), you must use the VMware anti-affinity rules to ensure that the two virtual machines are never on the same host, and that a host failure cannot result in the loss of both the active and standby VSM.

VMware vMotion does not complete when using an open virtual appliance (OVA) VSM deployment if the CD image is still mounted. To complete the vMotion, either click Edit Settings on the VM to disconnect the mounted CD image, or power off the VM. No functional impact results from this limitation.

If you are adding one host in a DRS cluster that is using vSwitch to a VSM, you must move the remaining hosts in the DRS cluster to the VSM. Otherwise, the DRS logic does not work, the VMs that are deployed on the VEM could be moved to a host in the cluster that does not have a VEM, and the VMs lose network connectivity.

For more information about vMotion of VSM, see the Cisco Nexus 1000V Software Installation Guide, Release 4.2(1)SV1(5.1).

Access Lists

ACLs have the following limitations and restrictions:

Limitations:

IPV6 ACL rules are not supported.

VLAN-based ACLs (VACLs) are not supported.

ACLs are not supported on port channels.

Restrictions:

IP ACL rules do not support the following:

fragments option

addressgroup option

portgroup option

interface ranges

Control VLAN traffic between the VSM and VEM does not go through ACL processing.

NetFlow

The NetFlow configuration has the following support, limitations, and restrictions:

Layer 2 match fields are not supported.

NetFlow Sampler is not supported.

NetFlow Exporter format V9 is supported

NetFlow Exporter format V5 is not supported.

The multicast traffic type is not supported. Cache entries are created for multicast packets, but the packet/byte count does not reflect replicated packets.

NetFlow is not supported on port channels.

The NetFlow cache table has the following limitation:

Immediate and permanent cache types are not supported.


Note The cache size that is configured using the CLI defines the number of entries, not the size in bytes. The configured entries are allocated for each processor in the ESX host and the total memory allocated depends on the number of processors.


Port Security

Port security has the following support, limitations, and restrictions:

Port security is enabled globally by default.
The feature/no feature port-security command is not supported.

In response to a security violation, you can shut down the port.

The port security violation actions that are supported on a secure port are Shutdown and Protect. The Restrict violation action is not supported.

Port security is not supported on the PVLAN promiscuous ports.

Port Profiles

Port profiles have the following restrictions or limitations:

There is a limit of 255 characters in a port-profile command attribute.

We recommend that you save the configuration across reboots, which will shorten the VSM bringup time.

We recommend that if you are altering or removing a port channel, you should migrate the interfaces that inherit the port channel port profile to a port profile with the desired configuration, rather than editing the original port channel port profile directly.

If you attempt to remove a port profile that is in use, that is, one that has already been auto-assigned to an interface, the Cisco Nexus 1000V generates an error message and does not allow the removal.

When you remove a port profile that is mapped to a VMware port group, the associated port group and settings within the vCenter Server are also removed.

Policy names are not checked against the policy database when ACL/NetFlow policies are applied through the port profile. It is possible to apply a nonexistent policy.

Telnet Enabled by Default

The Telnet server is enabled by default.

For more information about Telnet, see the Cisco Nexus 1000V Security Configuration Guide, Release 4.2(1)SV1(5.1).

SSH Support

Only SSH version 2 (SSHv2) is supported.

For more information, see the Cisco Nexus 1000V Security Configuration Guide, Release 4.2(1)SV1(5.1).

Cisco NX-OS Commands Might Differ from Cisco IOS

Be aware that the Cisco NX-OS CLI commands and modes might differ from those commands and modes used in the Cisco IOS software.

For information about CLI commands, see the Cisco Nexus 1000V Command Reference, Release 4.2(1)SV1(5.1).

Layer 2 Switching

This section lists the Layer 2 switching limitations and restrictions and includes the following topics:

No Spanning Tree Protocol

For more information about Layer 2 switching, see the Cisco Nexus 1000V Layer 2 Switching Configuration Guide, Release 4.2(1)SV1(5.1).

No Spanning Tree Protocol

The Cisco Nexus 1000V forwarding logic is designed to prevent network loops so it does not need to use the Spanning Tree Protocol. Packets that are received from the network on any link connecting the host to the network are not forwarded back to the network by the Cisco Nexus 1000V.

Cisco Discovery Protocol

The Cisco Discovery Protocol (CDP) is enabled globally by default.

CDP runs on all Cisco-manufactured equipment over the data link layer and does the following:

Advertises information to all attached Cisco devices.

Discovers and views information about those Cisco devices.

CDP can discover up to 256 neighbors per port if the port is connected to a hub with 256 connections.

If you disable CDP globally, CDP is also disabled for all interfaces.

For more information about CDP, see the Cisco Nexus 1000V System Management Configuration Guide, Release 4.2(1)SV1(5.1).

DHCP Not Supported for the Management IP

DHCP is not supported for the management IP. The management IP must be configured statically.

LACP

The Link Aggregation Control Protocol (LACP) is an IEEE standard protocol that aggregates Ethernet links into an EtherChannel.

The Cisco Nexus 1000V has the following restrictions for enabling LACP on ports carrying the control and packet VLANs:


Note These restrictions do not apply to other data ports using LACP.


If LACP offload is disabled, at least two ports must be configured as part of LACP channel.


Note This restriction is not applicable if LACP offload is enabled. You can check the LACP offload status by using the show lacp offload status command.


The upstream switch ports must be configured in spanning-tree port type edge trunk mode. For more information about this restriction, see the "Upstream Switch Ports" section.

Upstream Switch Ports

All upstream switch ports must be configured in spanning-tree port type edge trunk mode.

Without spanning-tree PortFast on upstream switch ports, it takes approximately 30 seconds to recover these ports on the upstream switch. Because these ports are carrying control and packet VLANs, the VSM loses connectivity to the VEM.

The following commands are available to use on Cisco upstream switch ports in interface configuration mode:

spanning-tree portfast

spanning-tree portfast trunk

spanning-tree portfast edge trunk

DNS Resolution

The Cisco Nexus 1010 (1000V) cannot resolve a domain name or hostname to an IP address.

Interfaces

When the maximum transmission unit (MTU) is configured on an operationally up interface, the interface goes down and comes back up.

VMware vShield Manager Issues Specific to Cisco Nexus 1000V

The following open caveats are specific to VMware vShield Manager and the Cisco Nexus 1000V.

CSCtx69398 - Unable to change the segment ID range on vShield Manager under certain conditions.

Symptom: A new segment ID range is rejected if it does not exclude IDs that already have been in use.

Conditions: This symptom might be seen when you try to change the segment ID range that excludes IDs that have already been in use.

Workaround: Use a new segment ID range that is a superset of the existing segment ID range.
