Command Usage
• Notifications are issued by the switch as trap messages by default. The recipient of a trap
message does not send a response to the switch. Traps are therefore not as reliable as inform
messages, which include a request for acknowledgement of receipt. Informs can be used to
ensure that critical information is received by the host. However, note that informs consume
more system resources because they must be kept in memory until a response is received.
Informs also add to network traffic. You should consider these effects when deciding whether
to issue notifications as traps or informs.
To send an inform to a SNMPv2c host, complete these steps:
1. Enable the SNMP agent (see “Configuring Global Settings for SNMP” on page 953).
2. Create a view with the required notification messages (see “Setting SNMPv3 Views” on
page 956).
3. Configure the group (matching the community string specified on the Configure Trap - Add
page) to include the required notify view (see “Configuring SNMPv3 Groups” on page 959).
4. Enable trap informs as described in the following pages.
To send an inform to a SNMPv3 host, complete these steps:
1. Enable the SNMP agent (see “Configuring Global Settings for SNMP” on page 953).
2. Create a local SNMPv3 user to use in the message exchange process (see “Configuring
Local SNMPv3 Users” on page 962). If the user specified in the trap configuration page
does not exist, an SNMPv3 group will be automatically created using the name of the
specified local user, and default settings for the read, write, and notify view.
3. Create a view with the required notification messages (see “Setting SNMPv3 Views” on
page 956).
4. Create a group that includes the required notify view (see “Configuring SNMPv3 Groups”
on page 959).
5. Enable trap informs as described in the following pages.
Parameters
These parameters are displayed:
SNMP Version 1
• IP Address – IPv4 or IPv6 address of a new management station to receive notification
message (i.e., the targeted recipient).
• Version – Specifies whether to send notifications as SNMP v1, v2c, or v3 traps. (Default: v1)
• 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 Configure Trap – Add page, we recommend defining it in
the Configure User – Add Community page.
• UDP Port – Specifies the UDP port number used by the trap manager. (Default: 162)
SNMP Version 2c
• IP Address – IP address of a new management station to receive notification message (i.e., the
targeted recipient).
