Switch Port Mapper does not work with Cisco Catalyst 9200L / 9300L
we have an issue with Switch Port Mapper's compatibility when used with Cisco Catalyst 9200L and 9300L switches. Despite configuring SNMP according to best practices and the required specifications, the tool fails to operate as expected on these devices.
Below is a sanitized version of my SNMP configuration for your reference:
ip access-list standard snmp-service
permit (IP of snmp server)
snmp-server view snmp-v3-ReadOnly-View iso included
snmp-server group snmp-v3-ReadOnly v3 priv read snmp-v3-ReadOnly-View access snmp-service
snmp-server user SOC-USER snmp-v3-ReadOnly v3 auth sha <REDACTED> priv aes 128 <REDACTED> access snmp-service
snmp-server group snmp-v3-ReadOnly v3 auth context vlan- match prefix
The configuration adheres to SNMPv3 best practices with the appropriate user, group, and views set up. However, Switch Port Mapper fails to retrieve port information (Mac and IP)
