Simple Network Management Protocol
NOTE: SNMP is an internet-standard protocol for managing devices on IP network and
a component of the Internet Engineering Task Force (IETF) Internet Protocol
Suite.
It is not the intent of this guide to define SNMP further than this and this
section is intended for users who are familiar with SNMP protocol.
The VN-Matrix 325 system can report alarm events via an SNMP trap, providing simple
integration with network management systems (NMS).
• When communicating using SNMP, the VN-Matrix 325 system complies with the
requirements of SNMP v3.
• When generating SNMP traps, the VN-Matrix 325 system complies with the
requirements of SNMPv1 or SNMPv2C (user-selectable using the SNMP filter settings
panel on the alarm logs page [see figure 52]).

SNMP variables that you may need to change include:
• The SNMP password
• The SNMP community value
• SNMP trap destination values

SNMP Password Value

The SNMP password is the same as the administrator password. By default this is set to
admin.
You must to enter the administrator password on the accounts page before SNMP can be
used. This process must be carried out for each of the following circumstances:
• When first using the system
• After a firmware upgrade to the system
A password for SNMPv3 must be exactly eight characters long.
• If the administrator password is less than eight characters in length then the remaining
characters are packed as follows: “admin“ becomes “adminadm” (exclusive of the
parentheses).
• If the administrator password is longer than eight characters then the value is
concatenated: “concatenate“ becomes “concaten” (exclusive of the parentheses).
NOTE: These password rules apply to the SNMP management software password
only and have no affect on the network interface login.
