5 Verify that the MMI and XPIC levels are appropriate. See
6 Configure LAG on the two Ethernet ports of the external switches connected
to the IP-20C units on both sides of the link.
7 Configure Automatic State Propagation with
ASP trigger by remote fault
enabled on the MIMO group in all four IP-20 units that make up the link. See
Configuring Automatic State Propagation and Link Loss Forwarding (CLI)
Note:
The last two steps are crucial to ensure that the link continues to
function via the MIMO resiliency mechanism in the event of a
hardware failure scenario.

Configuring a 2x2 MIMO Link (CLI)
1 Create a 2x2 MIMO group by entering the following command in root view:
root> radio mimo create group <1-4> mimo-type mimo-2x2 radio 2
port <first radio carrier in the group: either 1 or 2> radio 2
port <second radio carrier in the group: either 2 or 1>
2 Enable the group by entering the following command in root view:
root
> radio mimo set-admin group <1-4> admin enable
To reset MIMO, enter the following command in root view:
root
> radio mimo reset group 1
3 Verify that the XPIC levels are appropriate. See
Note:
XPI is not relevant for 2x2 MIMO.
14.8.5
Configuring a 1+0 or 2+2 Space Diversity Link (CLI)
1 Create a Space Diversity group by entering the following command in root
view:
root> radio mimo create group 1 mimo-type <mimo-type> radio 2
port <first radio carrier in the group: either 1 or 2> radio 2
port <second radio carrier in the group: either 2 or 1 >
where
<mimo-type>
defines the Space Diversity configuration. The options
are:
◦
1-plus-0-sd
–
1+0 Space Diversity.
◦
2-plus-0-sd
–
2+0 Space Diversity.
