Management and Configuration Guide K/KA/KB.15.15

The SNMP trap contains the following information.
DescriptionInformation
An assigned number that identifies a specific running configuration change
event.
Event ID
Method by which the change was made—CLI, Menu, or remote SNMP.Method
For configuration changes triggered by internal events, the term "Internal-Event"
is used as the source of the change.
Indicates the source address type of the network agent that made a change.
This is set to an address type of "unknown" when not applicable.
IP Address Type
IP address of the remote system from which a user accessed the switch. If not
applicable, this is an empty string and nothing is displayed, for example, if
access is through a management console port.
IP address
User name of the person who made the change. Null if not applicable.User Name
Date and time the change was made.Date and Time
The SNMP trap alerts any interested parties that someone has changed the switch's configuration
and provides information about the source for that change. It does not specify what has been
changed.
Source IP address for SNMP notifications
The switch uses an interface IP address as the source IP address in IP headers when sending SNMP
notifications (traps and informs) or responses to SNMP requests.
For multi-netted interfaces, the source IP address is the IP address of the outbound interface of the
SNMP reply, which may differ from the destination IP address in the IP header of the received
request. For security reasons, it may be desirable to send an SNMP reply with the IP address of
the destination interface (or a specified IP address) on which the corresponding SNMP request
was received.
To configure the switch to use the source IP address on which an SNMP request was received in
SNMP notification/traps and replies, enter the snmp-server response-source (page 210)
and snmp-server trap-source (page 211) commands.
Listening mode
For switches that have a separate out-of-band management port, you can specify whether a
configured SNMP server listens for SNMP queries over the OOBM interface, the data interface,
or both. By default, the switch listens over both interfaces.
This option is not available for switches that do not have a separate OOBM port.
The listening mode is set with parameters to the snmp-server command.
Advanced management: RMON
The switch supports RMON (remote monitoring) on all connected network segments. This allows
for troubleshooting and optimizing your network.
The following RMON groups are supported:
• Ethernet Statistics (except the numbers of packets of different frame sizes)
• Alarm
• History (of the supported Ethernet statistics)
• Event
