Info: If want to reboot with saving diagnostic information, input 'N' and then e xecute 'reboot save diagnostic-information'. Warning: The configuration has been modified, and it will be saved to the next s tartup saved-configuration file flash:/204.cfg. Info: The system is now comparing the configuration, please wait. Run the reboot command to restart the device.Info: The mac-num has been changed, and the change will take effect after a reboot. Info: Set public MAC address for master successfully. Info: This operation may take a few seconds. (The chassis chassis-id parameter is valid only in a CSS.) Run the set system-mac current hex-string command to configure the current MAC address of the device.(Optional) Run the display system-mac command to check the current and default MAC addresses of the device.To avoid address conflicts, you may need to change the MAC address on a device. In addition, you may need to use a specified MAC address for a device to suit your network requirements.

However, MAC address conflicts may occur because of incorrect configuration. Theoretically, each device has a unique MAC address. MAC addresses are managed and allocated by the IEEE. IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 0003-0003-0003 Last physical up time : -īillions of devices exist on global networks, and each device has a MAC address. PVID : 1, TPID : 8100(Hex), The Maximum Frame Length is 9216 Switch Port, Link-type : access(negotiated), For details, see the Hardware address field in the command output. Run the display interface ] command in any view or the display this interface command in the interface view to check the running status of the interface and check the configuration result.Run the mac-address mac-address command to configure a MAC address for the Ethernet interface.īy default, the system automatically allocates a MAC address to an Ethernet interface.Run the undo portswitch command to switch the Ethernet interface from Layer 3 mode to Layer 2 mode.īy default, an Ethernet interface works in Layer 2 mode.

Run the interface interface-type interface-number command to enter the interface view.

Ensure that the configured Ethernet interface MAC address does not conflict with an existing MAC address on the network.

Only X1E and LE1D2S04SEC0 cards support interface MAC address configuration.
