4.4.1 Ethernet MAC Daughter Card (E-MAC)
E-MAC is a MAC daughter card which can be installed on an EC-DMM or
Ethernet media modules. Figure 36 shows how you can install up to 6 E-MACs
on a single EC-DMM.

In addition to the DMM with an interface to the network, E-MAC allows you to
collect statistics about the Ethernet segment to which it is attached. The
statistics which are collected by E-MAC are passed to DMM which allows you to
display them locally or access them (in-band) through an application such as
RMonitor for AIX. Note that the communication between DMM and the E-MAC
installed on the 8260 media modules is via MLAN. For more information about
MLAN, please refer to 2.5.1.1, “The Management LAN (MLAN)” on page 26.
The E-MAC supports collection of a subset of the RMON statistics. For
information about RMON, and the E-MAC support it, please refer to Chapter 10,
“8260 RMON Support” on page 191.
4.4.1.1 Configuration E-MAC
Once you have installed an E-MAC card, you must perform the following
configuration steps:
1. Assign IP parameters to the segment to which the E-MAC is going to be
attached, as described in 4.2.4.5, “Configuring DMM IP Parameters” on
page 54.
