Hi everyone, For testing purposes, I am using Open vswitch to mirror traffic from 2 interfaces eth1 and eth2 to eth3. I am using the following command:
ovs-vsctl -- set Bridge br0 mirrors=@m \ -- --id=@eth1 get Port eth1 \ -- --id=@eth2 get Port eth2 \ -- --id=@eth3 get Port eth3 \ -- --id=@m create Mirror name=e1e2toe3 select-dst-port=@eth1 select-src-port=@eth1 output-port=@eth3 A node with tcpdump is connected to eth3. tcpdump shows only layer2 traffic: ARP, CDP (Cisco devices connected to eth1 and eth2) conversations between devices connected to eth1 and eth2, but no upper layers: ex: pings, ssh, telnet not visible. Any hint? AJ NOURI
