Configuration guidelines
• This feature is available only for the LSQ1SRP2XB and LSQ1SRP12GB SRPUs.
• To avoid forwarding loops, enable active/standby mode before you connect the Ethernet network
ports on the SRPUs.
Configuration procedure
To enable active/standby mode for the Ethernet network ports on the SRPUs:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable active/standby mode for
the Ethernet ports on the SRPUs.
strict-standby enable
Optional.
By default, concurrent mode applies.
Verifying and diagnosing transceiver modules
Verifying transceiver modules
You can verify the genuineness of a transceiver module in the following ways:
• Display the key parameters of a transceiver module, including its transceiver type, connector type,
central wavelength of the transmit laser, transfer distance and vendor name.
• Display its electronic label. The electronic label is a profile of the transceiver module and contains
the permanent configuration including the serial number, manufacturing date, and vendor name.
The data is written to the storage component during debugging or testing.
To verify transceiver modules, perform the following commands in any view:
Task Command
Display key parameters of
transceiver modules. display transceiver interface [ interface-type interface-number ] [ |
{ begin | exclude | include } regular-expression ]
Display transceiver modules'
electrical label information. display transceiver manuinfo interface [ interface-type
interface-number ] [ | { begin | exclude | include } regular-expression ]
NOTE:
The display transceiver manuinfo interface command cannot display information for some transceiver
modules.
Diagnosing transceiver modules
The device provides the alarm function and digital diagnosis function for transceiver modules. When a
transceiver module fails or inappropriately work, you can check for alarms present on the transceiver
module to identify the fault source or examine the key parameters monitored by the digital diagnosis
function, including the temperature, voltage, laser bias current, TX power, and RX power.
To diagnose transceiver modules, perform the following commands in any view:
