Port Lockdown
Cambium devices support access to various communication protocols and only the ports required for these
protocols are available for access by external entities. Operators may change the port numbers for these protocols
via the radio GUI or SNMP.

1813 Standard RADIUS accounting port Destination Port AP, SM
161 SNMP port Listen Port AP, SM
162 SNMP trap port Destination Port AP, SM
514 Syslog Destination Port AP, SM
Isolating SMs
In an AP, you can prevent SMs in the sector from directly communicating with each other. In CMMmicro Release
2.2 or later and the CMM4, you can prevent connected APs from directly communicating with each other, which
prevents SMs that are in different sectors of a cluster from communicating with each other.
In the AP, the SM Isolation parameter is available in the General tab of the Configuration web page. In the drop-
down menu for that parameter, you can configure the SM Isolation feature by any of the following selections:
•
Disable SM Isolation (the default selection). This allows full communication between SMs.
•
Block SM Packets from being forwarded . This prevents both multicast/broadcast and unicast SM-to-SM
communication.
