How to Change the Speed and Duplex of the Management Port
Resolution
To verify the PAN settings, issue the following CLI command:
> show system state filter net.eth0.hwcfg
net.eth0.hwcfg: { 'advertised': [ 10Mb/s-half, 10Mb/s-full, 100Mb/s-half, 100Mb/s-full, 1Gb/s-half, 1Gb/s-full, auto, ], 'link': Up, 'mode': Autoneg, 'setting': 100Mb/s-full, }
The speed and duplex information is at the end of the output. It is recommended this setting match the device that is connecting to the management port (either the switch or the workstation).
To change this setting from the CLI, run the following command:
> configure
# set deviceconfig system speed-duplex
100Mbps-full-duplex 100Mbps-full-duplex
100Mbps-half-duplex 100Mbps-half-duplex
10Mbps-full-duplex 10Mbps-full-duplex
10Mbps-half-duplex 10Mbps-half-duplex
1Gbps-full-duplex 1Gbps-full-duplex
1Gbps-half-duplex 1Gbps-half-duplex

If the following error GMX0_TX0_INT_REG[UNDFLW]TX Underflow is returned when doing a commit, there may be a speed/duplex negotiation mismatch between the PAN management port and the switch port to which it connects.
