Hi Jshen,
Did you find out more information on the VXLAN support on N7K VPC? It seems involves to get bridge domain and VLANs working on peer-link. I still didn't get the answer how to make bridge domain working on peer-link. The statement you are referring may not suggest VXLAN are not supported on vPC.
As for Physical Port vPCs, see the following for the concept:
Physical Port vPCs
Physical port vPCs are vPCs configured on the physical interface of a vPC peer devices. Physical port vPCs can optionally run Link Aggregation Control Protocol (LACP) to the downstream device. Physical port vPCs are supported on F2 and F2E modules. The vPC configuration is applied directly on the member port. You can also enable LACP protocol on the physical interface configured with vPC. From Cisco NX-OS Release 7.2(0)D1(1), physical port vPCs are supported on F3 and FEX modules as well.
This example shows how to configure Physical Port vPC on F2, F3, and FEX modules: switch# configure terminal switch(config)# interface ethernet 1/1
switch(config-if)# switchport
switch(config-if)# vpc 10 (under physical port directly instead of under the port channel)
switch(config-if-vpc)# lacp mode active
switch(config-if-vpc)# exit
Thanks.

Hi Luke,
Did you get the answer about your question? Is that possible to built a minimum VXLAN deployment with 2xNexus 5600 or 2xNexus 9300?
I read in some where it says that in VXLAN deployment, if Nexus 5600/9000 configured as LEAF, it will not be able to work as multicast RP. Cannot find the document anymore.

Hi ckendzora,
Thanks for the very detailed steps and the capture of the observations. Looking at your steps, this seems to be a procedure without interrupt to the wireless services. Is that correct?
Thanks.

Upgrading Cisco Unity Connection Guide:
8 Follow the upgrade process on the Unity Connection cluster:
• (RU upgrades only)
.....
• ( L2 upgrades only)
.....
9 Confirm that publisher server has Primary status and subscriber server has Secondary status.
10 (Unity Connection 9.1(2) or earlier versions only): If you are upgrading from Unity Connection 9.1(2) or earlier versions to Unity Connection 11.x, update the following virtual machine settings on both publisher and subscriber server through VMware vSphere client: a Change the Guest Operating System version to match the requirements of the Unity Connection 11.x. b Modify the network adapter to use the VMXNET 3 Adapter type.
CUCM doc indicates adapter should be changed before the upgrading. Please ask cisco TAC to clarify.

Hi,
I have an issue that Nexus 7702 doesn't see it's VPC Peer Nexus 7702 as CDP Neighbor.
E1/3 and E1/4 are the VPC Peer link between N7702-1-CORE-1 and N7702-1-CORE-2. This pair has been running for a while. Then I found E1/3 and E1/4 stops to see their VPC peer as CDP neighbor. LLDP does show CDP neighbor. After, shutdown and "no shutdown" E1/3, it started to see it's neighbor. "CDP enable", "no cdp enable" doesn't do the trick. A debugging of CDP shows E1/3 is trying to send CDP packet to it's peer but it never receiving CDP packet from peer. Likely a defect but just want to confirm the source. Code level is n7700-s2-kickstart.7.3.0.D1.1.bin and n7700-s2-dk9.7.3.0.D1.1.bin. CDP information on other ports are correct.

Hi Daniel,
I know this is pretty old a post. Just curious, did you migrate your network to MST?
MST looks pretty but it is very painful to when you need a new topology in your network. A change of VLAN to instance mapping would make multiple MST regions. In some platform, there isn't a method (there are VTP v3 but may not available across platforms) to propagate the MST configuration so it is a manual process and may need maintenance window to perform the work.
I think it is suitable more for static network. Just wondering what is your experience with your multi-tenant environment.
Peter really did a fantastic job in explaining the interactivity between MST and PVST. It must come from lots of real time experiences, not only through reading. Thank you Peter!
Thanks.
