nexus1000v and nexus1010 vlan id

Hi All,

When i read Cisco doc about nexus1010, i am a bit of confused about vlan id between nexus1010 and nexus1000v.

1000v have 3 vlan: mgmt, packet and controll. Let's say mgmt vlan=100, packet vlan=200, controll=300

1010 have mgmt and control vlan as well. I am quite sure that 1010 mgmt vlan should be the same as 1000v which is vlan 100.

How about controll vlan on 1010, should be the same as 1000v control vlan 300 or can be different.

If either case works, what's the recommendation from Cisco? ( I guess different control vlan for 1000v and 1010 is better)

nexus1000v and nexus1010 vlan id

Hi David,

The management VLAN is the only VLAN which needs to match between the Nexus 1010 and Nexus 1000v. This means the mgmt0 interface on the VSM needs to be on the same subnet as the mgmt0 interface that the Nexus 1010 appliance uses.

The control VLAN could be the same between the N1010 and N1Kv but it doesn't have to be.

Additionally, the Domain ID used needs to be different between the N1010 and N1Kv. Each svs-domain pair must have a unique domain-id.  For example, the N1010 pair could share a domain-id of 10 and the first N1Kv pair would share domain-id 20.

So to make this specific to your example:

* Nexus 1010

   - Management: VLAN 100

   - Control: Could be VLAN 300 or something different (up to you)

   - Domain ID: XX

* Nexus 1000v

   - Management: VLAN 100

   - Control: VLAN 300

   - Domain ID: YY

   - Packet: VLAN 200

Hope that helps clarify things for you.

Thanks,

Michael

Please see the Cisco recommendations on this link.

Cisco recommends using distinct vlans for control and packet traffic.
