By default, the routing platform’s management Ethernet interface (fxp0) uses as its MAC address the MAC address that is burned into the Ethernet card. To display this address, enter the show interface fxp0 operational mode command.
To change the management Ethernet interface’s MAC address, include the mac statement at the [edit interfaces fxp0] hierarchy level:
- [edit interfaces fxp0]
- mac mac-address;
Specify the MAC address as six hexadecimal bytes in one of the following formats: nnnn.nnnn.nnnn (for example, 0011.2233.4455) or nn:nn:nn:nn:nn:nn (for example, 00:11:22:33:44:55).
Note: When you integrate a standalone T640 routing node into a routing matrix, the PIC MAC addresses for the integrated T640 routing node are derived from a pool of MAC addresses maintained by the TX Matrix platform. For each MAC address you specify in the configuration of a formerly standalone T640 routing node, you must specify the same MAC address in the configuration of the TX Matrix platform.
