Server 2012 R2 Not Capturing Monitor-Session Packets
Hi All,
I've configured a monitor session on a Cisco NCS5501, that is dumping the mirrored traffic to a HP Proliant G8 running Server 2012 R2 on NIC #2.
I can blatantly see that the monitor session is sending traffic to NIC 2 on the server, but WireShark doesn't pick up any incoming traffic,
I've tried installing 3.0.1 & 2.6.8 - same behavior... I have Wireshark running at a remote site on a laptop (same monitor session configuration, and that is not having any issues capturing the traffic.
Any thoughts?

So, what do the NIC counters on the server tell you?
And were you capturing in promiscuous mode on the port?
Hi All,
Yes, capturing in promiscuous mode on the port, and now that I look at the NIC Counters... the server is incrementing the ReceivedDiscardedPackets.
I have confirmed that this is occurring on both Server 2012R2 & Server 2016 this morning.
The ReceivedDiscardedPackets & the ReceivedPacketErrors are both incrementing simultaneously
I found this link, attempted to install WinPCAP 10 and still no dice...
