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).

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.
|
