Are you in the ADMIN VDC to define the interfaces? I think you are in the child VDC and trying to allocate the interface. ... View more

What is the NX-OS version you are running. You need atleast 6.2.6 to support the inter-operability. Check the release notes below.   http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/nx-os/release/notes/62_nx-os_release_note.html#77519     ... View more

There are couple of options to do this. Are you running any routing protocol with the ISP for peering, BGP, OSPF etc? 1. Use two default routes with different AD values. 2. Floating static routes 3. Play with the metric if using routing protocols 4. IP SLA Object tracking with Floating static route.     ... View more

Please see this procedure that i mentioned on the top of the post. ********** option 2: By changing the PL to another port-channel, I will lose all vPC PO isn't it?   Answer: Yes, but in this case you will have two parallel PO's running between the chassis. M1 based PO which is PL and M2 based PO which is non PL. Shutdown the PL on primary, secondary shuts down the port. Traffic flows through primary, Remove the PL config from M1-PO and Put it on M2 PO, keep both the sides in shut state and then non shut after the PL configuration.   **********   Hope this helps.   ...

Hi Mark, I am extremely sorry you felt like that. This is the first time i had a look at your post. Technically, LISP IGP assist is not a hardware tunnel, under the hood its IGP--LISP redistribution so if you have a hardware that could support that redistribution and provide routes to M2, it should work. I dont have the configs ready yet as the feature is yet to make it on NX-OS. The last time, i heard that its been pushed a bit further.   WHat's you hardware and software config on Nexus boxes?   Cheers, -amit singh ... View more

You can use 40GE ports for VPC peer-link. No need to break those to 10G. ... View more

Hi NM, Yes, that's the idea. That should work with little disruption. The key is to shutdown the peerlink on Primary and migrate the PL config to M2.   Hope this helps.   Cheers, -amit singh ... View more

Well, if you change the spanning port type, there will be a slight disruption but port will transition to forwarding immediately so you could have a few pings timeout. This will be fairly quick though.   There is no specific V-switch config that someone can provide. I dont know that process. As far as you have the uplink ports defined and your VM's connect to the " port-group", that all should work fine. ... View more

It should be " Spanning-tree port type edge trunk " If you are doing a port-channel to ESX, I would put the mode "ON".     ... View more
