2+2 HSB Space Diversity utilizes two PTP 820C units operating in dual core mode. In each PTP
820C unit, both radio carriers are connected to a single antenna. One optical GbE port on each PTP
820C is connected to an optical splitter. Traffic must be routed to an optical GbE port on each PTP
820C unit.
In effect, a 2+2 HSB configuration is a protected 2+0 Space Diversity configuration. Each PTP 820C
monitors both of its cores. If the active PTP 820C detects a radio failure in either of its cores, it
initiates a switchover to the standby PTP 820C.
MIMO Mate Management Access (CLI)
For MIMO configurations using in-band management and an external switch operating in LAG
mode, you must enable MIMO Mate Management Access in order to manage both units via in-
band management. When MIMO Mate Management Access is enabled, the two units exchange
incoming management packets, ensuring that all management data is received by both units.
Note that MIMO Mate Management Access should only be enabled if both of the following
conditions exist:
In-band management
External switch using LAG
If either of these conditions is not present, MIMO Mate Management Access should be disabled,
otherwise in-band management may be lost. By default, the feature is disabled.
To enable MIMO Mate Management Access, enter the following command:
root> radio mimo mate mng
access
set admin enable
To disable MIMO Mate Management Access, enter the following command:
root> radio mimo mate mng access set admin disable
To display whether MIMO Mate Management Access is enabled, enter the following command:
root> radio mimo mate mng access show
Creating a MIMO or Space Diversity Group (CLI)
Note
Only one MIMO or Space Diversity group can be created per PTP 820C unit.
1.
To create a MIMO or Space Diversity group, enter the following command:
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 MIMO or Space Diversity configuration. The options are:
mimo-2x2
– 2x2 MIMO.
mimo-4x4
– 4x4 MIMO.
