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.
