Configuration Notes
- The management interfaces of different AR models are:
AR151: Ethernet0/0/3
AR160: GigabitEthernet0/0/0
AR207: Ethernet0/0/6
AR1200: GigabitEthernet0/0/0
AR2220: GigabitEthernet0/0/0
AR2240: GigabitEthernet0/0/2
AR3200: GigabitEthernet0/0/2
- When performing the last two steps, ensure that users on the serial port are kept online.
- The preceding method cannot be used on the AR1200 of V200R001C00SPC200 or an earlier version. You must delete the configuration file in the BootROM menu and reset the passwords after the system restarts.
