Greetings,
We've been seeing some very strange behavior with some devices on our network. We have devices that are statically configured on a specific subnet. Yet, these particular devices are being mysteriously assigned DHCP from a different subnet. This behaviour just started happening a few days ago. Clearly, this simply shouldn't be happening. First of all, these devices are supposed to be statically configured, second, they're on a subnet that is NOT configured for DHCP. Third, the DHCP leases they're getting are from a separate subnet, which means that somehow DHCP request packets are crossing subnets which makes no sense. We have a network where there are Juniper EX-2200s at the access layer. One of these switches may have been damaged by a power surge. Does anybody have any idea about this?
