Information About the Domain

You must create a domain name for Cisco Nexus 1000V and then add control and packet VLANs for communication and management. This process is part of the initial setup of the a Cisco Nexus 1000V when installing the software. If you need to create a domain later, you can do so using the setup command or the procedures described in this chapter.

Creating the Domain

Use this procedure to create a domain name for the Cisco Nexus 1000V that identifies the VSM and VEMs; and then add control and packet VLANs for communication and management. This process is part of the initial setup of the Cisco Nexus 1000V when installing the software. If you need to create a domain after initial setup, you can do so using this procedure.

BEFORE YOU BEGIN

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

If two or more VSMs share the same control and/or packet VLAN, the domain helps identify the VEMs managed by each VSM.

You are logged in to the CLI in EXEC mode.

You must have a unique domain ID for this Cisco Nexus 1000V instance.

You must identify the VLANs to be used for control and packet traffic.

Cisco recommends using distinct vlans for control and packet traffic.

Cisco recommends using distinct vlans for different instances of Nexus 1000V (different domains)

The svs mode command in the SVS Domain Configuration mode is not used and has no effect on a configuration.

For information about changing a domain ID after adding a second VSM see the Cisco Nexus 1000V High Availability and Redundancy Reference, Release 4.0(4)SV1(1).

SUMMARY STEPS

1. config t

2. svs-domain

3. domain id domain-id

4. control vlan vlan-id

Step 2 

svs-domain


Example:

n1000v(config)# svs-domain

n1000v(config-svs-domain)#

Places you into the   SVS Domain Configuration mode.

Step 3 

domain id number


Example:

n1000v(config-svs-domain)# domain id 100

n1000v(config-svs-domain)#

Creates the domain ID for this Cisco Nexus 1000V instance.

Step 4 

control vlan number


Example:

n1000v(config-svs-domain)# control vlan 190

n1000v(config-vlan)#

Assigns the control VLAN for this domain.

Step 5 

packet vlan number


Example:

n1000v(config-vlan)# packet vlan 191

n1000v(config-vlan)#

Assigns the packet VLAN for this domain.

Step 6 

show svs-domain


Example:

n1000v(config-vlan)# show svs-domain

Displays the domain configuration.

Step 7 

exit


Example:

n1000v(config-vlan)# exit

n1000v(config)#

Returns you to CLI  Global Configuration mode.

Step 8 

copy running-config startup-config


Example:

n1000v(config)# copy running-config startup-config

(Optional) Copies the running configuration to the startup configuration.

Example:
n1000v# config t 
n1000v(config)# svs-domain
n1000v(config-svs-domain)# domain id 100
n1000v(config-svs-domain)# control vlan 190
n1000v(config-svs-domain)# packet vlan 191
n1000v(config-vlan)# exit

n1000v (config)# show svs domain
SVS domain config: 
  Domain id:    100
  Control vlan: 190
  Packet vlan:  191
  L2/L3 Aipc mode: L2
  L2/L3 Aipc interface: mgmt0
  Status: Config push to VC successful.

Creating the Control VLAN for the Domain

Use this procedure to add a control VLAN to the domain.

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 have already configured and enabled the required switched virtual interface (SVI) using the document, Cisco Nexus 1000V Interface Configuration Guide, Release 4.0(4)SV1(1). The SVI is also called the VLAN interface and provides communication between VLANs.

You are familiar with how VLANs are numbered. For more information, see the document,
Cisco Nexus 1000V Layer 2 Switching Configuration Guide, Release 4.0(4)SV1(1).

Newly-created VLANs remain unused until Layer 2 ports are assigned to them.

SUMMARY STEPS

1. config t

2. vlan vlan-id

3. name vlan-name

4. state vlan-state

5. exit

6. show vlan id vlan-id

7. copy running-config startup-config

DETAILED STEPS

 
Command
Purpose

Step 1 

config t


Example:

n1000v# config t

n1000v(config)#

Places you into CLI  Global Configuration mode.

Step 2 

vlan 30


Example:

n1000v(config)# vlan 30

n1000v(config-vlan)#

Creates VLAN ID 30 for control traffic and places you into CLI VLAN Configuration mode.

Note If you enter a VLAN ID that is assigned to an internally allocated VLAN, the CLI returns an error message.

Step 3 

name cp_control


Example:

n1000v(config-vlan)# name cp_control

n1000v(config-vlan)#

Adds the descriptive name, cp_control, to this VLAN.

Step 4 

state active


Example:

n1000v(config-vlan)# state active

n1000v(config-vlan)#

Changes the operational state of the VLAN to active.

Step 5 

show vlan id 30


Example:

n1000v(config-vlan)# show vlan id 30

Displays the configuration for VLAN ID 30.

Step 6 

exit


Example:

n1000v(config-vlan)# exit

n1000v(config)#

Returns you to CLI Global Configuration mode.

Step 7 

copy running-config startup-config


Example:

n1000v(config)# copy running-config startup-config

(Optional) Copies the running configuration to the startup configuration.
