Why Does a Switch Record an SNMP/4/SNMP_IPLOCK Log?

Why Does a Switch Record an SNMP/4/SNMP_IPLOCK Log?

By default, the IP address blacklist of SNMP is enabled. If an NMS fails to log in to the switch through SNMP, the NMS IP address is added to the SNMP blacklist and locked for 1s. At the same time, the switch records an SNMP/4/SNMP_IPLOCK log. For the SNMP login failure reasons, see Why Cannot a Device Connect to the NMS Through SNMP?.

To disable IP address blacklist, run the snmp-agent blacklist ip-block disable command in the system view. After the blacklist is disabled, the switch will not record the SNMP/4/SNMP_IPLOCK log.
