Specs
In summary, the two delays work together to allow the network to stabilize, then to allow enough traffic to
arrive in order to produce meaningful results. Note that when the MoCA Quick Test is launched while
the unit is currently synchronized to a network, the “initialize” delay is never used; however, packet count
and result registers are always reset before proceeding with any MoCA Quick Test analysis. If a “settle”
delay is configured, it is always implemented regardless of whether the unit was synchronized initially.
The unit is preconfigured with defaults for these settings. If you do not know the precise settings that are
applicable to your testing architecture, Spirent recommends that you maintain the defaults.
7.6 System menu settings/controls (for MoCA)
Under System > System/Module Settings > MoCA-RF Module > MoCA, the following areas are
available that control important module settings:
• Vendor MAC Address on page 7-27
• Thresholds on page 7-28
7.6.1 Vendor MAC Address
(Select System > System/Module Settings > MoCA-RF Module > MoCA > Vendor MAC Address)
The Vendor MAC lookup table associates MAC addresses with equipment manufacturers/vendors, used
to correlate an address with its respective vendor in the Node Stats screens (see Node Stats page
(MoCA Network Statistics) on page 7-13.) That is, the unit is able to determine MAC addresses from the
network, but it may need to use this table to correlate an address with a vendor name. During testing, if
the unit is unable to correlate an address with a vendor in this table, it reports the vendor as Unknown.
Typically, the IEEE issues MAC addresses to a specific vendor in blocks which can be identified by the
first 6 octets (first 6 hexadecimal digits). As such, the lookup table should contain any 6-digit prefixes that
the unit might encounter, along with the vendors to which they apply. From the factory, the table is
prepopulated with a set of known values for current MoCA equipment vendors. If necessary, the screen
allows you to edit and augment the table. Note that the Description is for informational purposes only
within the lookup table.
