"clear arp-cache x.x.x.x" should work. Just keep in mind that after doing this, the local router will send an arp request to this mac. If it's still active, a reply is sent back and the local arp table will be filled again (you can check the "Age" counter).

On some platforms, "conf t" +"no arp a.b.c.d" can do this, but I
haven't tried it on ME6524. Is "clear arp interface <xxx>" where <xxx>
is the interface where the arp entry is located won't probably be that
hard, unlesss you have thousand of entries on that routed or SVI
interface.


"no arp a.b.c.d" doesn't work :(
"clear arp x.x.x.x" doesn't exist either.
"clear arp-cache interface GigabitEthernet 1/10" is not clearing arp
entries from GigabitEthernet1/10.215


How to display mac learned on a routed subinterface
"sh mac-address-table" don't display mac addresses for ports like Gi1/10.200
I don`t think routed subinterfaces have mac-address-table, by
definition... ping <broadcast address of Gi1/10.200> (use both
all-zeros and all-ones broadcasts) followed by show ip arp gi1/10.200
will likely show whoever is attached to that interface (even for hosts
that don't answer ping, because it's not common to filter out arp
requests/responses in host firewalls these days).

Ok ! But the box is still a switch. It uses internal vlans.
