Configuration Guidelines for Port Mirroring Analyzers on page 7
You can configure an analyzer to define both the input traffic and the output traffic in
the same analyzer configuration. The input traffic to be analyzed can be either traffic
that enters or traffic that exits an interface or VLAN. The analyzer configuration enables
you to send this traffic to an output interface, instance, next-hop group, VLAN, or bridge
domain. You can configure an analyzer at the
level.
You can define a set of mirroring properties, such as mirroring rate and maximum packet
length for traffic, that you can explicitly bind to physical ports on the router or switch.
This set of mirroring properties constitutes a statistical analyzer (also called a nondefault
analyzer). At this level, you can bind a named instance to the physical ports associated
with a specific FPC.
You can configure an analyzer without configuring any mirroring properties (such as
mirroring rate or maximum packet length). By default, the mirroring rate is set to 1 and
the maximum packet length is set to the complete length of the packet. These properties
are applied at the global level and need not be bound to a specific FPC.
You can apply up to two statistical analyzers to the same port groups on the switching
device. By applying two different statistical analyzer instances to the same FPC or Packet
Forwarding Engine, you can bind two distinct Layer 2 mirroring specifications to a single
port group. Mirroring properties that are bound to an FPC override any analyzer (default
analyzer) properties bound at the global level on the switching device. Default analyzer
properties are overridden by binding a second analyzer instance on the same port group.
Table 3 on page 5 lists some port mirroring analyzer terms and their descriptions.
Description
In a mirroring configuration, the analyzer includes:
The name of the analyzer
Source (input) ports, VLANs, or bridge domains
