Note:
To reduce the risk of being attacked by malicious users against opened socket and
enhance switch security, the S3900 series Ethernet switches provide the following
functions, so that a socket is opened only when it is needed:
Opening UDP port 161 (used for SNMP Agent) and UDP port 1024 (used for
SNMP-trap Client) when SNMP function is enabled;
Closing UDP port 161 and 1024 when SNMP is disabled.
The preceding functions are implemented as follows:
When you enable SNMP Agent by using the snmp-agent command or any of the
above snmp-agent configuration commands, UDP port 161 and 1024 are opened
at the same time.
When you disable SNMP Agent by using the undo snmp-agent command, UDP
port 161 and 1024 are closed at the same time.

1.3 Configuring Trap

Trap is the information that the managed device initiatively sends to the NMS without
request. Trap is used to report some urgent and important events (e.g., the managed
device is rebooted).
