VN-Matrix 300 • Alarms and SNMP 65
Overview — SNMP
The VN-Matrix 300 system has the ability to report alarm events via an SNMP trap, providing
simple integration with Network management systems (NMS).
When communicating using SNMP the VN-Matrix 300 complies with the requirements of
SNMP v3.
When generating SNMP traps the VN-Matrix 300 complies with the requirements of SNMPv1
and SNMPv2C.
Using SNMP — Password
The SNMP password is the same as the administrator password. By default this is set to
admin.
It is necessary to enter the administrator password in the accounts a page before SNMP can
be used. This process must be carried out for each of the following circumstances:
z When rst using the system
z After a firmware upgrade to the system
A password for SNMPv3 is required to be 8 characters long.
z If the administrator password is less than 8 characters in length then the remaining
characters are packed as follows:
admin becomes adminadm
z If the administrator password is longer than 8 characters then the value is
concatenated:
concatenate becomes concaten
SNMP Trap Version
The VN-Matrix 300 supports both version 1 and version 2 SNMP traps (SNMPv1 and
SNMPv2c).
SNMP Community
The SNMP Community value acts as a password. It is used to authenticate messages
between the VN-Matrix 300 system and the NMS. By default the Community string is set to
public. The Community string must match that in use by the NMS; if not then it may not be
possible to manage the VN-Matrix 300 device.
SNMP Trap Destinations
The Filter Settings dialogue in the Alarm Logs page is used to add and remove destination
IP addresses for NMS servers.
Figure 49. Filter Settings Dialog Box
The IP address of the NMS should be entered in the Create Trap Destination box.
Multiple destinations may be added.
