1.16 What is the difference between the always-on and once-on options when registering an ONU using password authentication?
1.1 Are the default username and password for MA5800 the same as those for MA5680T?
Question: Are the default username and password for MA5800 the same as those for MA5680T?
Answer: Based on the latest password security policy, the default username and password for MA5800 is root/admin123, and the default username and password for MA5680T have also been changed from root/admin to root/admin123 since V800R017C00. To improve the security of the communication network, it is recommended to change the password when logging into the device for the first time.
1.2 Forgot MA5800 account password
Question: What should I do if I forget my MA5800 account password?
Answer: Method 1: If the customer remembers the device's read/write community name, they can use an SNMP tool (such as net-snmp) to issue a command to change the root password, for example, change the root password to admin123.
snmpset -c community_name -v2c device_ip .1.3.6.1.4.1.2011.6.3.10.1.1.2.114.111.111.116 x 01
92 02 3a 7b bd 73 25 05 16 f0 69 df 18 b5 00
Method 2: If the customer remembers the BIOS password, they can enter the BIOS interface and load a blank database of the corresponding version, or a database of the corresponding version with the root password remembered.
1.3 What is the IP address of the MA5800 maintenance port?
Question: What is the IP address of the MA5800 maintenance port?
Answer: The default IP address of the MA5800 maintenance port (ETH port on the main control board) is 10.11.104.2.
1.4 MA5800 Telnet Login Failure
Question: Newly configured MA5800 Telnet connection failure (MA5800 Telnet login failure)?
Answer: The Telnet protocol is disabled by default. You need to use the `sysman service telnet enable` command to enable the Telnet service.
Telnet has security risks due to its inherent protocol limitations; Stelnet is recommended.
1.5 Can the MA5800 Optical Module Illumination Be Adjusted?
Question: Can the MA5800 optical module illumination be adjusted?
Answer: Optical module illumination is factory-configured; the device cannot control optical module illumination via command line.
1.6 Does the MA5800 Support Master/Standby Working Mode?
Question: Does the MA5800 support master/standby working mode?
Answer: The MA5800 does not support master/standby working mode; it only supports load-sharing working mode. The MA5800 employs a distributed architecture.
When dual main control boards are configured, both the primary and backup main control boards simultaneously handle services, effectively utilizing their bandwidth.
Each main control board consists of a control section and a switching section.
The control sections of both main control boards operate in a primary/backup mode. The board with its control section in primary mode is called the primary main control board, and the board with its control section in backup mode is called the backup main control board. When the primary main control board's control section experiences a fault, reset, or other abnormality, the services on that board automatically switch to the backup main control board's control section, ensuring uninterrupted main control functions and related services.
The switching sections of both main control boards operate in a load-sharing mode. In this mode, the system's maximum switching bandwidth is the maximum switching capacity of the two main control boards. When one main control board is removed or its switching section fails, the traffic on the failed main control board automatically switches to the other main control board. In this case, the system's maximum switching bandwidth is the maximum switching capacity of the single main control board.
Because the MA5800 does not support master/standby operation mode, the following configurations are not supported:
Protection between the primary and standby main control boards.
Protection between the ports of the primary and standby main control boards.
Protection between the primary main control board aggregation group and the backup main control board aggregation group.
1.7 Can the MA5800 and MA5680T boards be reused?
Question: Can the MA5800 and MA5680T boards be reused?
Answer: The MA5800 uses a completely new hardware architecture and cannot reuse the MA5680T boards.
1.8 Can a 10G PON board be used with a PON ONU?
Question: Can a 10G PON board be used with a PON ONU?
Answer: A 10G EPON board can be used with an EPON ONU, but a 10G GPON board cannot be used with a GPON ONU.
Therefore, an EPON ONU can be cut over to a 10G EPON port, but a GPON ONU cannot be cut over to a 10G GPON port.
1.9 How to change the MA5800 uplink port from 10GE to GE?
Question: How to change the MA5800 uplink port from 10GE to GE?
Answer: The MA5800 can use either the main control board or the uplink board for uplink, supporting 10GE/GE uplink. The default uplink port is 10GE, which can be set using the `speed` command. To avoid communication problems with upper-layer devices, the uplink port speed must be consistent with the port speed of the connected device.
1.10 How to switch the MA5800 to Chinese interface?
Question: How to switch the MA5800 to Chinese interface?
Answer: The MA5800 supports Chinese starting with version V100R016C10SPC201. The language attribute can be switched using the `switch language-mode` command.
1.11 Why does adding an MA5800 to a U2000 result in an error message indicating that this type of device does not exist?
Question: Why does adding an MA5800 to a U2000 result in an error message indicating that this type of device does not exist?
Answer: U2000 supports MA5800 devices starting from version V200R014C60. It is recommended to use a network management version compatible with the MA5800 version.
MA5800 versions V100R020C00 and later do not support U2000.
1.12 Can the existing power distribution box for the MA5680T network model support the installation of the MA5800?
Question: If the MA5800 is installed in the existing MA5680T rack, can the existing power distribution box for the MA5800 be installed?
Answer: They are not completely compatible due to power consumption limitations. When coexisting in the same rack, the service boards are configured based on the remaining power supply capacity of the existing rack's power distribution system.
1.13 What are the version query commands for the MA5800 device?
Question: What are the version query commands for the MA5800 device?
Answer:
1. Use the `display patch all` command to query the current system version and running patch information.
2. Use the `display language` command to query the currently running system version information, i.e., the information of the main control board.
3. Use the `display version frameid/slotid` command to query the C-level version and single-board hardware version of the main control board.
1.14 How to query and modify the ARP aging time on the MA5800?
Question: How to query and modify the ARP aging time on the MA5800?
Answer: The ARP aging time can be queried and modified using the following commands:
Query ARP aging time: In `display arp config`, the `ARP entry aging-time(min)` parameter is the ARP entry aging time.
Modify ARP aging time: `arp aging-time`.
1.15 Upgrade loading progress is stuck at 99%, how to handle?
Question: MA5800 upgrade loading progress is stuck at 99%, how to handle?
Answer: During the MA5800 upgrade process, you can use the command `display progress load` to check the package file loading progress. It will pause for a while at 99%, please wait patiently.
1.16 What is the difference between the `always-on` and `once-on` options when registering with ONU using password authentication?
Question: What is the difference between the `always-on` and `once-on` options when registering with ONU using password authentication?
Answer: `always-on`: Password authentication is used every time you log in; the MAC/SN parameter is not needed during registration. After `always-on` authentication, you can modify the SN or MAC.
`once-on`: Password authentication is used for the first login (the time can be set). After authentication, it is bound to the MAC/SN. Subsequent logins do not require a password and directly use the MAC/SN for authentication. Once-once authentication is completed, the SN or MAC address cannot be modified.
