SNMP trap configuration
The SNMP trap configuration defines how traps are set. Choose from the tabs
Trap1–Trap 5 to configure each trap. Table 15 describes the SNMP configuration
parameters.
Table 15. SNMP trap configuration parameters
Parameter
Trap Version
Trap 1 Enabled
Trap Address a
Trap Community
Description
Specifies the SNMP version (1, 2, or 3) with which to format traps.
Enables or disables the trap. If disabled, traps are not sent to trap monitoring
stations and the trap settings are not configurable.
Specifies the IP address to which SNMP traps are sent. A maximum of
5 trap addresses are supported. The default address for trap 1 is
10.0.0.254. The default address for traps 2–5 is 0.0.0.0.
Trap community password (up to 32 characters) that authorizes an
SNMP agent to receive traps. This field is write only. The value on the
switch and the SNMP management server must be the same. The
default is “public”.
Trap Port 1 The port number on which the trap is sent. The default is 162.
Trap Severity
Trap User
Users
Specifies a severity level to assign to the trap. Open the drop-down list
and choose a level. The Trap 1 Enabled option on the SNMP Properties
dialog must be enabled to access this drop-down list. Trap severity levels
include Unknown, Emergency, Alert, Critical, Error, Warning,
Notify, Info, Debug, and Mark.
The Trap User field becomes active when the V3 option is selected.
Click the Users button to modify the contents of the Trap User
drop-down list.
The Users button becomes active when the V3 option selected in the
Trap Version drop-down list. Click the Users button to open the
SNMPv3 dialog from which to add/remove users from the list.
Changes made to the user list will be updated in the user drop-down in
the SNMP Properties dialog.
a
Trap address (other than 0.0.0.0) and trap port combinations must be unique. For example, if trap 1 and trap 2 have the
same address, then they must have different port values. Similarly, if trap 1 and 2 have the same port value, they must
have different addresses.
SNMP v3 security
Simple Network Management Protocol Version 3 (SNMPv3) is an interoperable
standards-based protocol for network management. SNMPv3 provides secure
access to devices by a combination of authenticating and encrypting packets over
the network. SNMP v3 security is an additional layer of security offered with the 9.0
firmware. The SNMP v3 security is available to a switch that has a secure
connection, and can be configured only on the entry switch. The security features
provided in SNMPv3 are:
• Message integrity—ensuring that a packet has not been tampered with during
transit.
• Authentication—determining the message is from a valid source.
• Encryption—scrambling the contents of a packet to prevent it from being seen by
an unauthorized source.
