Management SVI Nexus 5548

[velo84]

Hello

I want to configure management for some Nexus 5548's and have a couple of questions which I was hoping for some help on.

I wanted to manage the switches via an SVI.  I have read the following document which gives details about the Management SVI but doesn't answer all questions.

http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/layer2/513_n1_1/b_Cisco_n5k_layer2_config_gd_rel_513_N1_1_chapter_0100.html#task_71991D8EFFB54DAB893C5E0855FF7AFD

I am not running any layer 3 functionality on the switch, no layer3 license (which it mentions in the above link) Will I still be able to create a management SVI.  I know I will need to enable the feature 'interface-vlan' to setup a Management SVI, does that require a license?

Thanks

Mark

I've not tested management SVI in any deployment but feature interface-vlan doesn't require a L3 or special license.

HTH,

Thanks for the reply Jerry, do you know why it says this in the link I posted in my original post? "Install the Layer 3 license"

Thanks

Configuring a VLAN as a Routed SVI

You can configure a VLAN to be a routed switch virtual interface (SVI).

Before You Begin

• Install the Layer 3 license. For more information, see License and Copyright Information for Cisco NX-OS Software available at the following URL:http://www.cisco.com/en/US/docs/switches/datacenter/sw/4_0/nx-os/license_agreement/nx-ossw_lisns.html.
• Make sure you understand the guidelines and limitations of this feature. For information, see Guidelines and Limitations for SVIs.

You can have single VLAN without the L3 license. Please see below output on my L2 only Nexus 5020 (no L3 capability on this box):

Thanks a lot for your help Jerry.

I'm assuming it can be any VLAN for the one SVI and not specific to VLAN 1 right? E.g I would want to set it up on VLAN 10.

Thank you

[Jerry Ye]

Yes, this is correct. You can use different VLAN ID. You also have to create a default route also.
