Information About Network Uplink Configurations

Cisco Nexus Virtual Services Appliance product family supports two types of network uplink configurations to connect to the network:

Flexible Network Uplink Configuration

Flexible network configuration offers complete flexibility to connect Cisco Nexus Virtual Services Appliance to the network, thus enabling appropriate traffic segregation policies like VSB traffic segregation.

This configuration consists of the following features:

  • Complete flexibility in terms of port configuration and usage
  • Flexible building of ports into a port channel.
  • Flexible assignment of a port or port channel to a VSB interface.
  • Easy uplink configuration.
  • Ability to achieve maximum uplink.

The default flexible network uplink configuration is the basic configuration with each physical port acting as uplink See Figure 3-1 and includes the following features:

  • Every physical port individually forms an uplink.
  • Each uplink can be configured independently.
  • Ability to achieve maximum uplink of 6Gbps.
  • No default redundancy for uplinks.
  • Physical ports cannot be bundled in a port channel.
  • VSB traffic is segregated by default.
  • VSB interface can be manually configured to share a port.

Figure 3-1 Default Flexible Network Uplink Configuration

If the flexible configuration is selected during installation of Cisco Nexus Virtual Services Appliance, then the default configuration is used to connect to the network. See the Cisco Nexus Virtual Services Appliance Software Installation and Upgrade Guide, Release 4.2(1)SP1(5.1) for more information.

You can then make changes to the default flexible network uplink configuration to suit your needs:

Figure 3-2 Assigning uplinks to flexible network configuration

 

Figure 3-3 Adding port channels to flexible network configuration

Static Network Uplink Configuration

In a static network configuration, the Cisco Nexus Virtual Services Appliance product family is connected to the network using four fixed network uplink configurations.

  • In configuration 1, control traffic, management traffic and data traffic share a single uplink.
  • In configuration 2, control traffic, and management traffic share an uplink and data traffic is a separate uplink.
  • In configuration 3, control traffic, and data traffic share an uplink and management traffic is a separate uplink.
  • In configuration 4, control traffic, management traffic and data traffic are all on separate unlinks.

For more information on uplink configurations, see Uplinks.

Guidelines and Limitations

Follow these guidelines and limitations when configuring the Cisco Nexus Virtual Services Appliance:

  • A change to the uplink type does not take effect until you reload the software.
  • Changing the uplink type is disruptive and leads to service disruption.
  • You can change the uplink type only once before issuing a reboot.
  • Use Table 3-1 when modifying the network uplink type.

 

Table 3-1 Uplink Usage

Uplink Type
Usage

1

When only the Cisco Nexus 1000V VSM is installed.

2

When only NAM is installed.

3

When the management and data traffic upstream must be separated.

4

When the management and data traffic upstream must be separated and control and data traffic must also be separated.

Modifying the Uplink Type

Use this procedure to modify the uplink type on an operational Cisco Nexus Virtual Services Appliance.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

  • You are logged in to the CLI in EXEC mode.
  • You must reload the Cisco Nexus Virtual Services Appliance pair in order to activate the changes made in this procedure. This procedure includes a step for reloading.

Caution To prevent loss of connectivity, you must reconfigure the uplink switches to correspond with the change made in this procedure.

• The following are supported uplink types and the ports that carry each type of VLAN traffic.

Migrating from Static Network Uplink to Flexible Network Uplink

Use this procedure to migrate from static network uplink type to flexible network uplink type.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

  • You are logged in to the CLI in EXEC mode.
  • By default, the control and management traffic are assigned to Ethernet1.
  • After you change the uplink type from static to flexible, you can configure the port channel and assign uplink assignment to a VSB manually.
  • You must reload the Cisco Nexus Virtual Services Appliance pair in order to activate the changes made in this procedure.
  • Changing the uplink type from static to flexible is disruptive and leads to service disruption. After you change the uplink type from static to flexible, you must save the configuration and reload for new configuration to take into effect.
  • When you change the uplink type from static to flexible, all the port channel, native VLAN, and port state configuration and retained in the flexible network type.

SUMMARY STEPS

1. config terminal

2. network uplink type number

3. network uplink type keyword

4. (optional) svs-domain

5. (optional) control uplink interface name

6. (optional) management uplink interface name

Note: Save the configuration and reload to bring the system with new network_uplink

 

Example:

switch(config)#)# network-uplink type flexible force

Note: The command will change network-uplink type and network-uplink type cannot be changed again before reload. Change to [1-4] network-uplink type will lead to loss of native vlan config on all ports.

Note: Save the configuration and reload to bring the system with new network_uplink

 

Changes the uplink type for the Cisco Nexus Virtual Services Appliance from static to flexible.

Note You can change the network type only once. In order to change the network type again, you must reload and then change the network type.

You can use the force option to skip the confirmation step.

Step 4

switch(config)# svs-domain

switch(config-svs-domain)#

 

(optional) Configure an SVS domain and enter SVS domain configuration mode

Step 5

Migrating From Flexible Network Uplink to Static Network Uplink

Use this procedure to migrate from flexible network uplink to static network uplink.

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

  • You are logged in to the CLI in EXEC mode.
  • This procedure is disruptive since both the active and standby should be reloaded together.
  • You must reload the Cisco Nexus Virtual Services Appliance pair in order to activate the changes made in this procedure. This procedure includes a step for reloading.

Caution To prevent loss of connectivity, you must reconfigure the uplink switches to correspond with the change made in this procedure.

• The following are supported uplink types and the ports that carry each type of VLAN traffic.

There is no traffic segregation based on traffic class

For a description of each uplink, see the “Uplinks” section.

• When you migrate from flexible network uplink type to static network uplink type, all the port channel, native VLAN, and port state configuration are lost.

• You must ensure that the uplink connectivity should be same as what is required for that static network uplink type.

• If the system is not configured in required uplink type, then shutdown the system from ILO after saving the configuration for both active and standby and then reload.

Assigning a Native VLAN to a Port Channel

Use this procedure to configure a native VLAN corresponding to an Ethernet interface. This procedure is applicable to both static and flexible network uplink type. Native VLAN changes can take effect immediately except for cases which involve Cisco Nexus Virtual Services Appliance VLANs and interfaces

BEFORE YOU BEGIN

Before beginning this procedure, you must know or do the following:

  • You are logged in to the CLI in EXEC mode.
  • You cannot assign native VLAN to an Ethernet interface which is a part of a port channel
  • You can add an Ethernet interface to a port channel only if the Ethernet interface and the port channel have the same native VLAN configuration.
  • After you configure the native VLANs in Cisco Nexus Virtual Services Appliance, you must also configure all the upstream switches with the same native VLAN.
  • When you modify the control or management native VLAN uplink configuration, you must first save the configuration and then shutdown Cisco Nexus Virtual Services Appliance from ILO . Now you can change native VLAN configuration on the uplink switch and then restart the Cisco Nexus Virtual Services Appliance.
  • When you change the network uplink configuration from flexible to static, all the ports and port channels will loose their native VLAN configuration.
  • When you delete an Ethernet interface from a port channel, its retains the native VLAN configuration.
