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).
