Troubleshooting Tip: Port not learning mac-address

[yabhishek]

Description	This article describes how to troubleshoot the issue when mac-address is not getting learned on the port.
Scope	FortiSwitch.
Solution	In some scenarios, while moving a client from one port to another, the switch does not learn the mac-address on another port.  Below are some steps which can be performed to troubleshoot the issue: Run the cable diagnostic on the port and check if the output is correct: diagnose switch physical-ports cable-diag <port_number> Check the linerate on the port to verify if there are any Rx packets or not: diagnose switch physical-port linerate <port_name> Check if the mac-address is already available in the MAC table of the switch: diagnose switch mac-address list | grep <mac-address> If the mac-address is already present on any port, then check if that port has sticky-mac enabled on it: config switch interface     edit <port_name>         config switch interface             edit "port2"                 set trust-ip-dscp-map ''                 set default-cos 0                 set qos-policy "default"                 set ptp-policy "default"                    set ptp-status enable                    set sticky-mac disable ----------------> This must be disabled.                    set log-mac-event disable                    set nac disable     next end
