RSPAN on 2960

Hello!

I try to configure RSPAN on 2960 switch. But nothing sends to the destination switch. When I try to do the same in 2950 everything works fine. Here is the configuration of the 2960:

----------------------

CUS_48ports_2#sh run vl 100

Current configuration:

!

vlan 100

name Test

remote-span

end

CUS_48ports_2#sh monitor

Session 1

---------

Type : Remote Source Session

Source Ports :

Both : Fa0/24

Dest RSPAN VLAN : 100

-------------------------------

However during configuration of RSPAN I get a message from the switch about reflector-port:

--------------------------------

CUS_48ports_2(config)#mon ses 1 d rem vl 100

%Note: ingoring the reflector port configuration

--------------------------------

I checked the 100 VLAN on both switches: it presents on the trunk, and it's configured on the destination switch:

--------------------------------

CUS-48ports#sh run vl 100

Building configuration...

Current configuration:

!

vlan 100

name Test

remote-span

end

CUS-48ports#sh mon

Session 1

---------

Type : Remote Destination Session

Source RSPAN VLAN : 100

Destination Ports : Fa0/31

Encapsulation : Native

Ingress: Disabled

--------------------------------

Could you advice something to solve the issue?

It happens that even in 2020 this may be issue for similar platform 2970, while I just need to run RSPAN by an accident .

Per documentation found reflector config isnot needed, nor is present in the CLI - it's just broken
