Hi All.

I searched this question but I'm not finding anything relevant, or I'm not understanding the results properly. I have all my L2 switches remote management access, SSH/SFTP, configured on a specific vlan 12, with subnet Route goes through a Barracuda NGFW with firewall rules restricting traffic to/from vlan 12.

I picked up a Nexus 3064 I'm looking to use as a core router for my vlans. My question is, how do I specify the management vrf to use vlan 12 for management so it's on the same subnet as the rest of the LAN switches?

Do I specify the ip on int mgmt0 like, then specify the SVI vlan12 with an ip as the to be the subnet gateway like

Thanks for any clarification.

  • SSH/TFTP that is

If you are using in-band management (vlan 12), then you don’t need a separate VRF. You can simply use the SVI for vlan 12. Be sure to apply the appropriate ACL to the management interface.

Mgmt0 is a physical interface for out of band management.

Alternatively you can connect the mgmt0 interface to an access port on vlan 12. The FW is your default gateway for the VRF.

  • Oh great. So I don't really need to worry about the specific Management vrf and just make the SVI like the others under default vrf with acl for in-band? That's simple. Thank you so much.
