Port-Mapping Acl - HP FlexNetwork MSR Series Command Reference Manual

If the destination port of a packet matches a general port mapping, APR recognizes the packet as the
specified application protocol's packet.
If two port mappings are configured with the same port number and transport layer protocol, 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 general port mapping of port 3456 to FTP.
<Sysname> system-view
[Sysname] port-mapping application ftp port 3456

Parameters
application application-name: Specifies an application protocol by its name, a case-insensitive
string of 1 to 63 characters. The names invalid and other are not allowed.
port port-number: Specifies a port by its number in the range of 0 to 65535.
protocol protocol-name: Specifies a transport layer protocol by its name, including:
•
dccp: Specifies DCCP.
•
sctp: Specifies SCTP.
•
tcp: Specifies TCP.
•
udp: Specifies UDP.
•
udp-lite: Specifies UDP-Lite.
acl [ ipv6 ] acl-number: Specifies the number of an ACL, in the range of 2000 to 2999. To specify an
IPv6 ACL, include the ipv6 keyword. To specify an IPv4 ACL, do not include the ipv6 keyword.
Usage guidelines
APR uses ACL-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:
