Westermo OS Management Guide
Version 4.17.0-0
The WeOS SNMP trap support is integrated with the WeOS alarm handling sys-
tem (see
). This means that you as an operator have fine-grained
control of which traps to send. All traps in the list below, except Coldstart and
lldpRemTablesChange, can be controlled via the alarm handling system.
❼ Link Alarm: A trap is generated on link up or link down, given that Link Alarm
is enabled on that specific port (see
and
Link Down OID: iso(1).org(3).dod(6).internet(1).snmpV2(6).snmpModules(3).
snmpMIB(1).snmpMIBObjects(1).snmpTraps(5).linkDown(3)
Link Up OID: iso(1).org(3).dod(6).internet(1).snmpV2(6).snmpModules(3).
snmpMIB(1).snmpMIBObjects(1).snmpTraps(5).linkUp(4)
Note
When a port is being reconfigured, link down and link up events are
likely to occur. If link-alarm is enabled on that port, a couple of SNMP
traps are likely to be generated as a side-effect of the port reconfigura-
tion.
❼ Cold Start: A trap is generated when a system comes up.
OID: iso(1).org(3).dod(6).internet(1).snmpV2(6).snmpModules(3).
snmpMIB(1).snmpMIBObjects(1).snmpTraps(5).coldStart(1)
❼ LLDP Remote System Update: A trap is generated when a remote system
has updated.
OID: iso(1).std(0).iso8802(8802).ieee802dot1(1).ieee802dot1mibs(1).
lldpMIB(2).lldpNotifications(0).lldpNotificationPrefix(0).lldpRemTablesChange(1)
❼ Digital-In: A trap is generated when the voltage level on the pins of a
digital-in sensor changes from high to low, or low to high.
Digital-In High OID: iso(1).org(3).dod(6).internet(1).private(4).
enterprises(1).westermo(16177).common(2).weos(1).notifications(6).
sensorNotifications(1).sensorNotificationPrefix(0).digitalInHigh(1)
Digital-In Low OID: iso(1).org(3).dod(6).internet(1).private(4).
enterprises(1).westermo(16177).common(2).weos(1).notifications(6).
sensorNotifications(1).sensorNotificationPrefix(0).digitalInLow(2)
❼ Power Supply: A trap is generated when the voltage level on any of the
power feeds changes from high to low, or low to high.
