SG300-28PP - Error: Lock port Dynamic Enable prevents executing Copy Port Enable

[tnakano03]

I want to enable SPAN port on the SG300-288PP switch, However, when I tied to enable SPAN, I get the following error message but I don't have Port Security configure neither the source interface (Gi4) nor the destination interface (GI24). Is this a bug on the version? Or I have other ports configured with Port Security feature. Is this a problem?  

===Error

Update:

I tried the followings but no luck. Now I have a feeling this version or model doesn't support the SPAN.  Anyone configure SPAN on SG300-28PP?

1. I removed all port security confng from all ports

2. I removed all config on the destination port gi24

3. However, I still get the same error "Lock port Dynamic Enable prevents executing Copy Port Enable"

interface gigabitethernet24
no spanning-tree portfast

SQM-SG300(config-if)#port monitor gi4
Port gi24: Lock port Dynamic Enable prevents executing Copy Port Enable

Disable macro auto smartport under the interface. i.e. "no macro auto smartport"

Thank you for the suggestion. Still doesn't work... I am not sure what I can do next.

==Source Port

interface gigabitethernet4
switchport trunk allowed vlan add 150
no macro auto smartport

==Destination port

interface gigabitethernet24
no spanning-tree portfast

==Error

SQM-SG300(config)#int gi24
SQM-SG300(config-if)#port monitor GigabitEthernet 4
Port gi24: Lock port Dynamic Enable prevents executing Copy Port Enable

Hi @tnakano03 ,

Could you share the full result of the command show interface giga 24 and show interface giga 4?
