I'm having intermittent issues with DNS resolution where clients aim at a VIP for DNS, with requests farmed off to a cluster of resolvers. There is also a fairly vanilla group config for the VIP address and the services.Things generally work okay, b...

Zach,There's no sign of any connection issues under load.No interface errorsBucketloads of multicast traffic on one particular interface. This is an interface that connects to a pair of routers (running hsrp) and the switch also runs vrrp to its par...
