Command Usage
•If an snmp-server host command is not entered, no notifications are
sent. To configure the ECN330-switch to send SNMP notifications, enter
at least one snmp-server host command. To enable multiple hosts,
issue a separate snmp-server host command for each host.
•The snmp-server host command is used in conjunction with the
snmp-server enable traps command. Use the snmp-server
enable traps command to enable the sending of traps or informs and
to specify which SNMP notifications are sent globally. For a host to
receive notifications, at least one snmp-server enable traps
command and the snmp-server host command for that host must be
enabled.
• Some notification types cannot be controlled with the snmp-server
enable traps command. For example, some notification types are
always enabled.
• Notifications are issued by the ECN330-switch as trap messages by
default. The recipient of a trap message does not send a response to
the ECN330-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. 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 section 7.6.1 on page 609).
