Usage guidelines
APR uses subnet-based host-port mappings to recognize packets. A packet is recognized as an
application protocol packet when it matches all the following conditions in a mapping:
• The packet is destined for the specified IP subnet in the mapping.
• The packet's destination port matches the specified port in the mapping.
• The transport layer protocol that encapsulates the packet matches the specified transport layer
protocol if you specify a transport layer protocol in the mapping.
If multiple subnet-based mappings are applied to packets and these subnets overlap, APR matches
the packets destined for the overlapped segment with the port mapping of the subnet that has the
smallest range.
If two port mappings are configured with the same port number, transport layer protocol, and subnet,
but with different application protocols, the most recent configuration takes effect.
A mapping with the transport layer protocol specified has a higher priority than one without it.
Examples
# Create a mapping of port 3456 to FTP for the packets sent to the IPv4 hosts on subnet 1.1.1.0/24.
<Sysname> system-view
[Sysname] port-mapping application ftp port 3456 subnet ip 1.1.1.0 24
# Create a mapping of port 3456 to FTP for the packets sent to the IPv6 hosts on subnet 1:: /120.
<Sysname> system-view
[Sysname] port-mapping application ftp port 3456 subnet ipv6 1:: 120

Parameters
interface interface-type interface-number: Specifies an interface by its type and number. If you do
not specify an interface, this command clears application statistics for all interfaces.
Examples
# Clear application statistics for GigabitEthernet 1/0/1.
<Sysname> reset application statistics interface gigabitethernet 1/0/1
# Clear application statistics for all interfaces.
