Use Nexus 9000 as Layer 2 LAN switch

[dbuckley77]

I have a Nexus 9k that I'm trying to configure as a basic L2 switch like all of the 2960X switches we have on our network.  I have an etherchannel configured between the Nexus 9K and out Cisco 6807 core.  All of the routing for our inside networks is done on the 6807.  Instead of using the dedicated management interface on the Nexus 9K i have setup our management vlan and it's corresponding vlan interface with an IP like I do on all of our other LAN switches.  However I cannot get to that IP from the LAN and can't set the default gateway on the Nexus 9K.  How do I make it like all of our other LAN switches?

It would be easier to give good advice if we knew more about how you have configured the switch. But here are some things to use as a start:

- does this switch have connectivity to the core? show cdp neighbor is a good way to check this.

- which vlan are you using for management and is that interface in an up state? show ip interface brief is a good way to check this.

- is the switch seeing any neighbors on the management vlan? show arp is a way to check on this.

- is ip routing enabled on the switch? Certainly on 2960X the default is routing not enabled, but I wonder if your 9k enables routing. If routing is enabled does the switch have a default route configured? Or if routing is not enabled does the switch have ip default-gateway configured? The output of show ip route might shed some light on this.

only add VLAN to DB in NSK by

vlan xxx

this only step you missing I think
