Hola José, tu afirmación es correcta.
Si ejecutamos show version podrías obtener la Base MAC address:
SW1#show version !output omitted cisco WS-C3560-48TS (PowerPC405) processor (revision G0) with 131072K bytes of memory. Processor board ID FDO1405X15Z Last reset from power-on 2 Virtual Ethernet interfaces 48 FastEthernet interfaces 4 Gigabit Ethernet interfaces The password-recovery mechanism is enabled. 512K bytes of flash-simulated non-volatile configuration memory. Base ethernet MAC Address : 30:37:A6:79:7F:00 Motherboard assembly number : 73-9898-09 Power supply part number : 341-0097-02 Motherboard serial number : FDO14050UXN Power supply serial number : DCA13528K8B
Si ejecutas show vtp status, verás ese mismo valor:
SW1#show vtp status *Apr 3 18:00:00.989: %SYS-5-CONFIG_I: Configured from console by consolestatus VTP Version capable : 1 to 3 VTP version running : 3 VTP Domain Name : cisco VTP Pruning Mode : Disabled VTP Traps Generation : Disabled Device ID : 3037.a679.7f00 30:37:A6:79:7F:00
