Director

Chapter 3

Conguring Filters Using the CLI

This chapter describes how to use the CLI to determine which monitoring tools are connected to which Network ports.

It also explains how to create lters to limit the amount of trafc copied to Monitor ports, so the monitoring tools

receive only the trafc that is of interest to them.

In this chapter, you will learn to:

Copy trafc from any Network port to any Monitor port•

Aggregate trafc from any set of Network ports to any Monitor port•

Regenerate trafc from any aggregated set of Network ports to any set of Monitor ports•

Create lters•

Create complex lters•

View lters•

Work with congurable 10 Gigabit ports•

Understand lter interactions•

For a complete listing of lter commands in the CLI, see Appendix B.

Syntax

In the CLI, Director ports are specied by alpha-numeric names as follows:

n1.1, n1.2, n1.3 .. n1.12 – Network ports in the rst DNM (the slot on the left); for in-line DNM models, port •

n1.1, n1.2 are an in-line link pair; so are n1.3, n1.4, and so on.

n2.1, n2.2, n2.3 .. n2.12 – Network ports in the second DNM (the slot on the right); for in-line DNM models, •

port n2.1, n2.2 are an in-line link pair; so are n2.3, n2.4, and so on.

m.1, m.2, m.3 .. m.10 – Monitor ports•

t.1, t.2 – Congurable 10 Gigabit ports (on the front panel)•

Most commands accept lists of ports. In port lists, port names are separated by commas and a dash (-) desig-

nates a range. Do not include any space characters in the list (do not put a space after the comma). For example,

n1.1,n1.2,n1.3,n1.4,n1.5-n1.10 is a list that includes Network Ports 1 through 10 on DNM 1.
