Usage Guidelines
A flow record requires at least one key field before it can be used in a flow monitor. The key fields distinguish
flows, with each flow having a unique set of values for the key fields. The key fields are defined using the
match
command.
The
input
and
output
keywords are used to specify the observation point that is used by the
match datalink
mac
command to create flows based on the unique MAC addressees in the network traffic.
When a datalink flow monitor is assigned to an interface or VLAN record, it creates flows only for non-IPv6
or non-IPv4 traffic.
Note
To return this command to its default settings, use the
no match datalink mac
or
default match datalink
mac
flow record configuration command.
