Run the following command to view interface information: display interface <interface-type> <interface-number> The output includes interface rate, module type, link status (the state being UP is a prerequisite for normal operation) and traffic statistics, which can be used for. Run the following command to view interface information: display interface <interface-type> <interface-number> The output includes interface rate, module type, link status (the state being UP is a prerequisite for normal operation) and traffic statistics, which can be used for. This document describes all the configuration commands of the device, including the command function, syntax, parameters, views, default level, usage guidelines, examples, and related commands. This document describes all the configuration commands of the device, including the command function. Taking the Huawei 5700 series switches as an example, the commands to view optical module information are as follows: Transceiver Type :1000_BASE_SX_SFP Connector Type :LC Wavelength(nm) :850 Transfer Distance(m) :300(50um),150(62. Figure 1 Schematic Diagram of Optical Module Connected to Switch 1. However, the general approach is similar across different models. Run the display transceiver [interface interface-type interface-number | slot slot-id], to view the information on. Commands provided in this section and all the parameters in the commands are supported by all switch models (except the S5731-L and S5731S-L), unless otherwise specified. For details, see specific commands. The check hardware health command displays health check information about the device.
