Huawei Technologies Proprietary
1-10
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:
z Opening UDP port 161 (used for SNMP Agent) and UDP port 1024 (used for
SNMP-trap Client) when SNMP function is enabled;
z Closing UDP port 161 and 1024 when SNMP is disabled.
The preceding functions are implemented as follows:
z When you enable SNMP Agent by using the snmp-agent command or any of the
snmp-agent configuration commands, UDP port 161 and 1024 are opened at the
same time.
z When you disable SNMP Agent by using the undo snmp-agent command, UDP
port 161 and 1024 are closed at the same time.
