This read-only octet string (0-16 bytes) holds the SNMP community string used when sending traps to this trap receiver, and the MIB notes it is writable only through the ComController's own console-based CUI, not via SNMP. An admin cross-checks this value against what the NMS expects when traps aren't being accepted. For example, when a receiving NMS rejects incoming traps, the admin reads this community string here and discovers it must log into the CC console to correct the mismatch.
