Creating port maps in the CLI
To create port maps using the CLI, use the set map command. For example, to create a mapping for the following
ports:
1A -> 1B, 1C
1B -> 1A, 1D
Enter these commands at the prompt:
If you want to add filters to a map, use the following command:
Here, filter1 is applied as a ‘require’ filter and will only allow through traffic which matches its condition. filter2 is
applied as an ‘exclude’ filter and will remove all traffic that matches its condition. See page 136 for information on
the set map command.
Typical map configurations
This section describes some commonly deployed map configurations used when setting up network TAPs.
Breakout TAP
A breakout TAP copies packets travelling in one direction (A to B) to a output port (C), and packets travelling in
the other direction (B to A) to another output port (D).
Use breakout maps when:
• 100% guaranteed traffic collection is required.
• The network analyzer has dual ports running at the same speed as the live network.
Aggregation TAPs
An aggregation TAP takes packets from two or more network segments and sends them as single stream to one or
more output ports. It allows you to use just one monitoring tool to see all of your network traffic.
Use aggregating TAPs when
• 100% guaranteed traffic collection is not required. If the aggregated traffic rate exceeds the inbound network
bandwidth of the network tool, excess packets will be dropped at the monitoring port
• you want to use a single network tool to analyze several network segments
• the network tool has only a single interface.
Regeneration TAPs
A regeneration TAP sends packets from one network segment to two or more output ports. This allows you to
send a single traffic stream to a range of different monitoring tools, each serving a different purpose, whilst taking
traffic from the network only once.
