7.5.3 Daisychain Switch Mode
Daisychain switch mode sets the AAM to use Ethernet port one (
LAN 1
) as an uplink port to
connect to the Ethernet backbone and Ethernet port two (
LAN 2
) to connect to another
(daisychained or subtending) AAM. The daisychain switch mode is recommended for use in a
network topology that does not have loops. When you daisychain multiple AAMs they must
all be set to daisychain mode.
In daisychain switch mode, the AAM forwards IGMP queries from Ethernet port one (
LAN 1
)
to Ethernet port 2 (
LAN 2
) and to the ADSL ports. Daisychain switch mode is recommended
for using IGMP snooping with daisychained (cascaded) AAMs.
Daisychain switch mode with port isolation enabled blocks communications between
subscriber ports on an individual AAM and between the subscribers of any daisychained
AAMs (see
for an example). Use the same port isolation setting on all
AAMs that you set up in a daisychain.
7.5.4 Port Isolation with Daisychain Switch Mode Example
See the following graphic. AAM
1
has its Ethernet port one (
LAN 1
) connected to the Ethernet
backbone switch (
3
) and it's Ethernet port two (
LAN2
) connected to Ethernet port one (
LAN
1
) of the daisychained AAM
2
.
With port isolation turned on, communications between
A
and
B
must first go through another
switch or router (
3
in the figure).
A
and
B
also cannot communicate with
C
without their
communications going through another switch or router.
