10. Traps Summary
The A/B Switch can be configured to issue an SNMP trap when certain events occur. Use the "SET ALERTTYPE"
command to enable traps, and use the "SET MANAGER N X.X.X.X" command to specify the IP addresses of up to
16 different NMS computers that you want to send these traps to (see section 7 for details regarding these
commands). The following traps are generated by the A/B Switch. For additional details regarding theses traps, and
the SNMP MIB objects supported by the A/B Switch, please refer to the d1000.mib file supplied with your switch.
generic trap 0
generic trap 4
specific trap 6
specific trap 8
11. Syslog Messages
The A/B Switch can be configured to issue a syslog message rather than an SNMP trap when certain events occur.
To configure the A/B Switch to issue syslog messages, you must use the "SET ALERTTYPE" command to select
SYSLOG messages, and you need to specify the IP address(es) of the device(s) that will be receiving the syslog
messages by using the "SET MANAGER N X.X.X.X" command (see section 7 for details regarding these
commands). Once these configuration changes have been made, the A/B Switch will issue syslog messages for the
following types of events:
power up cold start, or restart using the RESET command
•
SNMP authentication failure (access attempted using incorrect read or write community name)
•
switching action caused by a user initiated command, front panel push button action, or remote dry contact
•
closure
auto switch or auto recovery switch functions
•
The syslog messages issued by the A/B Switch conform where possible to the general recommendations as
described in rfc3164. There is no real time clock within the A/B Switch however, so each syslog message uses a
default timestamp value of Jan 1 00:00:00. The device receiving the syslog messages will need to apply a timestamp
or other identifier if this information is needed. The general format for each syslog message from the A/B Switch is
as follows:
Jan 1 00:00:00 [IP address] Bypass Switch: [specific message based on the event that occurred]
Listed below is each type of syslog message that the A/B Switch can issue, followed by the actual syslog message
that the A/B Switch will send.
Syslog Messages
power up cold start (or RESET command)
Jan 1 00:00:00 192.168.1.151 Bypass Switch: Switch has been reset.
SNMP authentication failure
Jan 1 00:00:00 192.168.1.151 Bypass Switch: SNMP authentication failure.
system switch A to B via S S B command (or toggle switch)
Jan 1 00:00:00 192.168.1.151 Bypass Switch: System switch from A to B position.
A/B SWITCH WITH REMOTE INTERFACE
coldStart – issued when the unit is powered up, or after a RESET command
AuthenticationFailure – issued when an invalid SNMP read/write community name is
used when attempting to access the A/B Switch
SystemSwitchChange – issued in response to a switching action caused by a user initiated
command, front panel push button action, or remote dry contact closure
AutoSwitchChange – issued when the A/B Switch automatically changes connection
states via the auto switch feature, or the auto recovery feature
