◆ The maximum number of ACL rules that can be configured on the
switch is 128.
◆ The maximum number of ACL rules that can be bound to a port is 10.
◆ ACLs provide frame filtering based on any of the following criteria:
■
Any frame type (based on MAC address, VLAN ID, VLAN priority)
■
Ethernet type (based on Ethernet type value, MAC address, VLAN
ID, VLAN priority)
■
ARP (based on ARP/RARP type, request/reply, sender/target IP,
hardware address matches ARP/RARP MAC address, ARP/RARP
hardware address length matches protocol address length, matches
this entry when ARP/RARP hardware address is equal to Ethernet,
