PRISM 4151

SNMP C

ONFIGURATION

The SNMP Configuration screen (Figure 3-14) is accessible
for the SLIP, Ethernet or Token Ring SNMP interface. It
allows for the entry of those parameters required for proper
operation with an SNMP-based network manager.

The PRISM 4151 supports alarm reporting by SNMP
TRAPs when running the LAN or SLIP interface. If the
unit’s IP connection is LAN or direct SLIP, it expects an IP
connection to always be present and thus outputs its TRAP
messages immediately. If the IP connection is dial SLIP, the
unit dials out from the modem connected to the SLIP port
using the number programmed in the SNMP Configuration
screen and outputs trap messages upon connection.

The PRISM 4151 has an embedded SNMP agent supporting
MIB-2 and a proprietary DDS MIB. The SET command is
supported and has the functionality described below. The
PRISM 4151 also supports a single TELNET session.

SNMP Sets: This field enables or disables the set com-
mand responses for SNMP. Refer to Appendix C,
SNMP Agent, for detailed information on these responses.

TRAP IP Address: These six rows require numeric
entries. Each row contains four 3-digit numbers which are
separated by periods. Each of these numbers can range from
0 to 255.

These fields accept the IP address of a network device to
which alarm reporting traps are to be sent. The unit detects
and reports alarms and provides several options for report-
ing them, one of which is SNMP traps. When an alarm
occurs, the unit sends a trap message to up to six destina-
tions on the user’s network. The trap message is formatted

per RFC 1157. The generic trap type is enterprisespecific
(generic-trap = 6).

Up to six trap IP addresses can be assigned to report via
SNMP. The unit will report each alarm by transmitting an
SNMP trap to each trap IP address. DDS network problems
often cause more than one alarm type. In these cases, multi-
ple trap messages are generated, each with a different spe-
cific trap type.

The following five menu items allow the entry of up to 58
characters identifying the appropriate group, person, device
function, or unit location.

Read Community: This display accepts a character string
identifying the group authorized to perform read operations.
The default setting is public.

Write Community: This display accepts a character string
identifying the group authorized to perform write opera-
tions. The default setting is a null string (‘ ‘).

System Contact: This display accepts a character string
identifying the person responsible for a network device. The
default setting is no system contact.

System Name: This display accepts a character string iden-
tifying the functionality of the network device. The default
setting is no system name.

System Location: This display accepts a character string
identifying the physical location of network device. The
default setting is no system location.
