Mibs - D-Link DES-6300 User Manual

Modular L3 Ethernet Switch User's Guide
The following are trap types a trap manager will receive:
Cold Start – This trap signifies that the Switch has been powered up and
initialized such that software settings are reconfigured and hardware systems are
rebooted. A cold start is different from a factory reset.
Authentication Failure – This trap signifies that someone has tried to logon to
the switch using an invalid SNMP community name. The switch automatically
stores the source IP address of the unauthorized user.
Link Change Event – This trap is sent whenever the link of a port changes from
link up to link down or from link down to link up.
Power Fan1 Failure – This trap is sent whenever one of the two fans on a
redundant power supply module fails.
Power Fan2 Failure – This trap is sent whenever one of the two fans on a
redundant power supply module fails.
End TFTP – This trap is sent when TFTP service ends.
Abort TFTP – This trap is sent when TFTP service aborts.
Start TFTP – This trap is sent when TFTP service starts.
VLAN Dynamic Port Added – This trap is sent when a VLAN dynamic port is
added.
VLAN Dynamic Port Removed – This trap is sent when a VLAN dynamic port
is removed.

MIBs

Management information and counters are stored in the Switch in the Management Information
Base (MIB). The Switch uses the standard MIB-II Management Information Base module.
Consequently, values for MIB objects can be retrieved from any SNMP-based network manager
software. In addition to the standard MIB-II, the Switch also supports its own proprietary
enterprise MIB as an extended Management Information Base. These MIBs may also be
retrieved by specifying the MIB's Object-Identity (OID) at the network manager. MIB values
can be either read-only or read-write.
Read-only MIBs variables can be either constants that are programmed into the Switch, or
variables that change while the Switch is in operation. Examples of read-only constants are the
number of ports and types of ports. Examples of read-only variables are the statistics counters
such as the number of errors that have occurred, or how many kilobytes of data have been
received and forwarded through a port.
Read-write MIBs are variables usually related to user-customized configurations. Examples of
these are the Switch's IP Address, Spanning Tree Algorithm parameters, and port status.
If you use a third-party vendors' SNMP software to manage the Switch, a diskette listing the
Switch's propriety enterprise MIBs can be obtained by request. If your software provides
functions to browse or modify MIBs, you can also get the MIB values and change them (if the
MIBs' attributes permit the write operation). This process however can be quite involved, since
you must know the MIB OIDs and retrieve them one by one.
