Re: Migration to Nexus 5k best practices...

Hi,

Am rolling out a network for a Dc with netapp, can you please tell me any
document that expalin your statement

*Also, under the main VPC config, you should setup peer-gateway for your
NetApp management as it will consult the MAC address of the packet received
vs. its ARP table for replies. Peer-gateway allows the packet received
with the other HSRP peer MAC to traverse. If you don't feel comfortable
turning it on all VPC VLAN's, you can exclude ranges.
*
Thanks,
Vibs
