Section 5. SNMP-based Management
The modem is equipped with an SNMP port. It is possible to view the current device
modes, port and link states, local and remote error statistics accessing the device by
SNMP.
5.1. SNMP Parameters Setting
The following parameters must be set from the console to provide access to the device
over the SNMP protocol:
• IP address/netmask – the IP address of the Ethernet port, and the length of the net-
mask.
• Gateway IP address – the IP address of the routing gateway.
• Get community – information query access password.
• Get IP address/netmask – the IP address and the netmask length for the restriction
of information
query
access.
Information query access is permitted only for the hosts, whose IP addresses equal to
the one specified by the «Get IP address» parameter. The higher-order N bits are used
for IP address comparison. The value of N is specified by the “Netmask” parameter.
Additional parameters must be specified for access to parameter settings:
• Set community – access password for parameter setting.
• Set IP address/netmask – the IP address and the netmask length for the restriction
of access to parameter setting .
The access rights to set the parameters
must be granted to trusted hosts only.
In case of emergencies, the device is able to sent SNMP events reports (traps). The fol-
lowing parameters must be specified to enable this:
• Traps – enable/disable to send SNMP traps.
• Authentication traps – enable/disable to send SNMP traps about unauthorized access
attempts.
• Trap community – password for sending SNMP traps.
• Trap destination IP address – the IP address of the recipient of traps sent.
SNMP traps are sent when the following events occur:
• Modem power-on or reset causes the device to send the COLD START trap.
• Unauthorized access attempt over the SNMP protocol – the AUTHENTICATION
FAILURE trap.
• Loss of signal or framing on the E1 link – the LINK DOWN trap.
