I have a Brocade switch 7450 between 2 Cisco switches 3850. I have my PC connecting to port1 on Cisco sw1 and Wireshark on port1on Cisco sw2. I configured RSPAN on my Cisco switches. But I am not sure how to pass my RSPAN traffic on VLAN10 from sw1 to sw2. Any thoughts will be greatly appreciated. Thanks

You can try to disable MAC learning on brocade switch. Left switch also could need to be configured with mac-learn-disable.
I never tried it,so I have no idea will it work, but since it can be counted as any thoughts...

What does it mean by mac-learn-disable?

One of basic switch functions is MAC learning (to create port - MAC address association). I guess that in the case of rspan switch should act as hub (ports that are assigned to vlan that is used for rspan), since switch does not know where destination MAC address is located it will send packet to all ports that  are associated with current VLAN except the port on which packet is received.
