Aggregation configuration
Link aggregation in n+0 mode allows utilizing up to 1000 Mbps Ethernet Layer 2 throughput by
using independent frequency pair for each link. Traffic is being balanced (n+0) by internal switches of
Master link. In case of link aggregation n+0 traffic distribution between n links is based upon the
source and destination MAC addresses of Ethernet packets. Link aggregation (n+0) requires multiple
MAC to MAC address pair connections as path for each connection is chosen based upon Ethernet
frame’s source and destination MAC addresses.
In case of link aggregation n+0 OMT, dual-polarized antenna or coupler can be used.
When active link is down, in n+0 mode all connections are being switched to active links. Average
switchover time is 100ms.
Necessary equipment for CFIP PhoeniX link aggregation n+0
2, 3 or 4 CFIP PhoeniX links
1.
2 Gigabit Ethernet switches with at least n+2 ports (e.g. 4 ports for 2+0 configuration).
There are no special requirements for external switch (
SOHO
switches can be used).
General configuration guide
Do not interconnect CFIP PhoeniX IDUs with each other and do not plug CFIP PhoeniX IDUs into
switches before you have finished the configuration.
1.
Choose one link which will operate as “Master”. Other link will operate as “Slave”
2.
Configure each link separately in mode you would like to operate. All CFIP PhoeniX links
should operate in the same operational mode (bandwidth, modulation, Ethernet capacity)
3.
In case of link aggregation n+0 different frequencies should be set for master and slave links.
4.
Choose different IP addresses for each CFIP PhoeniX unit. Please see example given in
Figure
4.39.
5.
Remote IP address for all units should be entered manually. In order to do that in
“Tools
Command line” should be entered “
modem ipremote off
” command and afterwards
appropriate remote IP address entered in “Configuration
IP configuration”
6.
When you have configured both links proceed with n+0 configuration

Link aggregation 2+0 setup
IDU1 IP address - 192.168.205.10 – Master local unit
IDU2 IP address - 192.168.205.11 – Master remote unit
IDU3 IP address - 192.168.205.12 – Slave local unit
IDU4 IP address - 192.168.205.13 – Slave remote unit
