Advanced Management Features 10-5
Traps
Traps are unsolicited information from the SNMP agent. MonarchNet uses a
ColdStart trap to inform the manager it has been powered on or reset. An
authentication failure trap is sent when MonarchNet receives an SNMP trap
GET or SET request with an incorrect community name.
MonarchNet sends printer traps when there is a change in the status of the
printer. If the printer goes off-line, runs out of paper or is detached, the
administrator will be notified via the MonarchNet traps over both UDP and
IPX. Additionally, if the MonarchNet is attached to a printer that supports
bidirectional parallel ports and the Printer Job Language (PJL), the
MonarchNet can send traps on toner low, paper jam, and printer cover open.
The traps may be configured for specific destination addresses and can be
configured for a particular printer port and/or printer trap.
In order to receive Status traps, the MonarchNet must have bidirectional
status enabled (it is disabled by default). Extended Status can be enabled
through the MonarchNet Configuration utility (telnet) from the Configure Port
option. You can also enable Status through MonarchNet for TCP/IP from the
Output Port file tab.
If you do not see the option of enabling bidirectional
status support on either configuration utility, you may
need to upgrade your MonarchNet firmware. Also, verify
you are running MonarchNet for TCP/IP.
Security
SNMP implements a simple security system known as community names.
Each SNMP message has a community name associated with the command
in the message. SNMP allows for a Set community name, Get community
name and a Trap community name. When the SNMP Agent receives a
command, it checks the community name of the message with the community
name of the device. If the community names do not match, the Agent
discards the message and sends an authentication failure trap.
The MonarchNet Utilities and WebView allow you to specify the community
names and a trap destination IP address(es).
