Dual homing a server vPC to two FEXs

Hi all,

I have 2 N7010's in vPC topology running NX-OS 6.0.1 with some N2Ks attahced. I brought up a server today connected it via vPC to 2 FEXs and all seems to be working normally except while I was configuring the vPC I had some users report that they lost connectivity to some servers but able to reconnect after a few minutes. I wouldn't think that bringing up a vPC would cause disruption to the network but the timing is so coincidental. Anyone has any ideas or reason why the issue could be related to what I did ? Below is the vPC config on one of the N7K's. Thanks in advance !!!

interface port-channel14

  switchport

  switchport access vlan 8

  spanning-tree guard root

  spanning-tree bpdufilter enable

  flowcontrol send on

  vpc 14

interface Ethernet113/1/26

  description vPC member port

  switchport

  switchport access vlan 8

  spanning-tree port type edge

  spanning-tree guard root

  channel-group 14 mode active

  no shutdown

  description vPC member port

Hi,

Your config looks fine.  Adding a Portchannel should not effect any other server in production. As you noted, it was probably coincidental.

Thanks Reza !!!
