6.4 SNMP CONFIGURATIONS FOR pCOWeb
The page shown below summarizes the basic SNMP configurations for pCOWeb.
SNMP System Configurations
 Read/Write community – Read only community: specify the strings in accordance with the system NMS (see 6.1 on page 34).
 Read/Write network – Read only network: subnetworks that pCOWeb accepts Read/Write or Read only queries from; useful for restricting access
only to some NMS; for unlimited access, leave “default”.
 System name: installation identifier name; corresponds to the SNMP standard OID:
1.3.6.1.2.1.1.5.0
 System description: a textual description of the device; corresponds to the SNMP standard OID:
1.3.6.1.2.1.1.1.0
 System location: physical location of the installation; corresponds to the SNMP standard OID:
1.3.6.1.2.1.1.6.0
 System contact: e-mail address to contact for the management of the installation; corresponds to the SNMP standard OID:
1.3.6.1.2.1.1.4.0
 System OID: OID that identifies the device (it should be allocated in the SMI enterprises subtree 1.3.6.1.4.1); corresponds to the SNMP standard
OID:
1.3.6.1.2.1.1.2.0
 Enterprise OID: enterprises identifier used by the device. The default is 9839, which is the identifier assigned to CAREL; the full list of assigned
identifiers is available on https://www.iana.org/assignments/enterprise-numbers/enterprise-numbers. Users should change the identifier only if they
do not want pCOWeb to appear as a CAREL device.

SNMP Default traps configuration
 Default trap community: community enclosed with the TRAP notifications (see 4.3 on page 20) if the Host Community fields on the page shown in
 Figure 4.n are empty; if this Community is also left empty, the Host TRAP notifications with the empty Community will NOT be sent.
 Recipients enabled: recipients enabled to send the “System traps” (see below) defined on the page shown in
 Figure 4.n.
System traps
pCO protocol failure: a TRAP will be generated whenever pCO-pCOWeb communication is interrupted or re-established; this TRAP can be set, as
follows:
 Enabled: enabled to be sent.
 Trap OID: extended OID that describes the TRAP sent; the information will be sent without being processed by pCOWeb.
 Acknowledge / Ack interval: enable, select the maximum number of repeats and the time interval for sending the TRAP until reception is
acknowledged (similar to the Retry / Timeout fields corresponding to the TRAP messages generated by the events relating to the pCO variables,
see
 Figure 4.t).
