Is there an option to limit the maximum
number of MAC addresses that a 7500/7600
router is willing to learn for one L3
802.1q subinterface? Something like:

interface FastEthernet0/1.200
encapsulation dot1q 200
ip arp cache maximum-mac-addresses 50

Otherwise, would anyone suggest another
way to create a similar, per-VLAN limit
for ARP entries?

Thanks,
Everton
