SNMP communities
The
community strings
(names which can be regarded as passwords) in the SNMP
Communities section must conform to those configured in the SNMP manager. Often, these
are ‘public’, mainly used for the read and trap communities, and ‘private’ or ‘netman’, for
read-write operations. The manager program may offer additional choices.
SNMP traps
A C-54 E alarm status change will generate a trap which can be caught by any SNMP
manager.
Version
and
Destination IP : port
are required fields.
Version
The SNMP version used.
Destination IP : port
The IP address associated with the manager program and the
destination port (162 is the default port).
Alternative destination IP :
port
If desired, an alternative destination IP address and port can be
added.
Enable authentication trap
It is possible to add an authentication trap to be able to catch
attempts at access using the wrong community string.
Polling
Depending on facilities offered by the SNMP manager, a number of variables can be read out
and in a few cases be edited and set. The Ethernet port variables are contained in the
‘system’ and ‘interfaces’ sections of
RFC 1213-MIB
.
The example streams table (figure 7.63) is taken from the Castle Rock SNMPc manager,
OPTC section.
