Whether it is possible to throw RSPAN (cisco) through 2 switches (extreme) And its output on cisco?

Hello. There was a need to listen to traffic from the port which is quite far away.
Here's the gist.
Cisco 1: listen to 2 ports and send to vlan 1717
did it like this -
create vlan 1717
remote-span
monitor session 1 source interface f0/6 f0/7
monitor session 1 destination remote vlan 1717
Then there are 2 extremes in which the vlan is simply thrown with a tag.
on Cisco 2
create vlan 1717
remote-span
monitor session 1 source remote vlan 1717
monitor session 1 destination interface f0/5
At the end I do not see traffic. Is it not working like that or am I doing something wrong?
The same thing will need to be done with d-link 3552
UPD1
Now checked up - the traffic goes, only not that. Previously, I looked exactly at sip or ip, as it turned out - I get IP6 of some cameras that are somewhere in the network of one of the clients. And the packages are the same on completely different vlans.
Packets appear when I add a vlan source (from where to listen to traffic). And it doesn't matter if it's remote or not.
