Table 16-1 Snmp; Supported Traps - ZyXEL Communications IES-1000 User Manual

IES-1000 User's Guide
Base (MIB) is a collection of managed objects. SNMP allows manager and agents to communicate for the purpose
of accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a
request and the agent returns responses using the following protocol operations:
COMMAND
Get
GetNext
Set
Trap
16.1.1 Supported MIBs
The IES-1000 supports MIB II (defined in RFC-1213 and RFC-1215). The IES-1000 can also respond with
specific data from the ZyXEL private MIBs (zyxel.mib, zyxel-AS.mib, zyxel-AS-ATM.mib, zyxel-
AESCommon.mib and zyxel-SESCommon.mib). MIBs let administrators collect statistics and monitor status and
performance.
16.1.2

♦ coldStart Trap (defined in RFC 1215):
This trap is sent at system start-up.
♦ authenticationFailure Trap (defined in RFC 1215):

♦ linkUp Trap (defined in RFC 1215):
This trap is sent when a DSL port is up.
♦ linkDown Trap (defined in RFC 1215):
This trap is sent when a DSL port is down.
♦ overheat Trap (defined in ZYXEL-MIB):
