ARAMETERS
These parameters are displayed:
Trap Manager Capability – This switch supports up to five trap
managers.
Trap Manager IP Address – IP address of a new management station
to receive notification messages (i.e., the targeted recipient).
Trap Manager Community String – Specifies a valid community
string for the new trap manager entry. (Range: 1-32 characters, case
sensitive)
Although you can set this string in the Trap Managers table, we
recommend that you define this string in the SNMP Community section
at the top of the SNMP Configuration page (for Version 1 or 2c clients),
or define a corresponding “User Name” in the SNMPv3 > Users page or
SNMPv3 > Remote Users page (for Version 3 clients).
When sending SNMPv3 trap messages, the community string is used as
the name of a local user to identify the source of the trap messages
sent from this switch. If an account for the specified user has not been
created ( page 142 ), one will be automatically generated.
When sending SNMPv3 inform messages, the community string is used
as the name of a remote user to identify the source of the inform
messages sent from this switch. An account for the specified user must
be manually configured ( page 143 ).
Trap UDP Port – Specifies the UDP port number used by the trap
manager. (Default: 162)
Trap Version – Specifies whether to send notifications as SNMP v1,
v2c, or v3 traps. (Default: v1)
Trap Security Level – When trap version 3 is selected, you must
specify one of the following security levels. (Default: noAuthNoPriv)
noAuthNoPriv – There is no authentication or encryption used in
SNMP communications.
AuthNoPriv – SNMP communications use authentication, but the
data is not encrypted.
AuthPriv – SNMP communications use both authentication and
encryption.
Inform – Notifications are sent as inform messages. Note that this
option is only available for version 2c and 3 hosts. (Default:
Notifications are sent as trap messages)
Timeout – The number of seconds to wait for an acknowledgment
before resending an inform message. (Range: 0-2147483647
centiseconds; Default: 1500 centiseconds)
Retry times – The maximum number of times to resend an inform
message if the recipient does not acknowledge receipt.
(Range: 0-255; Default: 3)
