When configuring a port mirror to and from ESXi virtual machines for passive call recording we can see some mirrored traffic but cannot see any RTP traffic.

The virtual machines are on separate VMware vSwtiches to force the traffic through an x460-G2. The vSwitches and port groups are set in promiscuous security mode, the port groups are untagged.

The extreme switch ports are also untagged.

The mirror is configured as follows:

configure port mirror "voip" add port 1 ingress-and-egress
enable port mirror "voip" to port 2

When the same config is done on a basic HP 1920-G this set up works fine.

if you have multiple ports with multiple vlans on the x460 and esxi host, then you should be tagging the traffic.
