4.2.2 Access control configuration
Access Control defines accessibility of managers to the UPSLink SNMP agent. Only a manager from
the specified NMS can access UPSLink SNMP agent to exchange information and control actions. If
there is no specific IP address (all IP address are defaulted to 0.0.0.0), a manager from any host can
access the UPSLink SNMP agent with read-only privilege.
4.2.3 Trap receiver configuration
The trap receiver defines managers that can be notified of significant events (TRAP) from the UPSLink
SNMP agent. If there is no trap receiver, just give 0.0.0.0 for that.
SNMP traps for UPS alarms are sent as either of RFC1628 type or SENA type. The former is sent in
compliance with RFC1628 UPS MIB and the latter type of trap has an additional field to SNMP v1 trap
so that receivers could identify the cause easier. Table 0-2 shows the “specific types” field in the Sena
type of traps.
There is one more trap type ‘EASY_TRAP’. Select this type to send a Non-RFC1628 SNMP v1 trap
that is to be directly sent from UPS serial program. See ‘UPS serial programming guide’to learn more.
