Packet filter
packet-filter
{ ip-group
{ acl-number |
acl-name } [ rule rule ] |
link-group
{ acl-number |
acl-name } [ rule rule ] }
Packet filter only supports using the
ACL of deny operation.
The Layer-2 ACL supports using the
rules of MAC-MAC, MAC-PORT,
PORT-PORT, MAC-ANY, ANY-MAC,
PORT-ANY and ANY-PORT.
The Layer-3 ACL supports using the
rules of IP-IP, IP-NET, NET-NET,
IP-ANY, ANY-IP, NET-ANY and
ANY-NET.
