IP-Flow

IP-Flow This mask builds flows that have a specific source and destination port in addition to
specific source and destination IP addresses. Two different processes—for example, HTTP and
Telnet—from one client to a single server will create two different masks because the port numbers
are different. This mask is used if the outbound access control list is extended.
572 Chapter 18  Multilayer Switching (MLS)
If no outbound access control list is configured on the router but either IP-Flow or Source-
Destination-IP is desired, it is possible to configure the switch to build flows in a more specific
fashion. The command set mls flow [destination|destination-source|full] can be
used to tell the MLS switch what information to cache with candidate packets.
