Thanks. We'll let you know when a new response is added.

the access list will be
suppose the vlan 40 ip address range is 192.168.2.0/24
then
ip access list extended vlan 40
permit ip 192.168.2.0 0.0.0.255 192.168.2.0 0.0.0.255
permit ip 192.168.2.0 0.0.0.255 host 192.168.5.25
on root bridge
int vlan 40
ip access-group vlan 40 in
that’s it
