Operation
Create or update the
view information
Note:
An S3100 Ethernet switch provides the following functions to prevent attacks through
unused UDP ports.
Executing the snmp-agent command or any of the commands used to configure
SNMP agent enables the SNMP agent, and at the same opens UDP port 161 used
by SNMP agents and the UDP port used by SNMP trap respectively.
Executing the undo snmp-agent command disables the SNMP agent and closes
UDP ports used by SNMP agent and SNMP trap as well.
