When dealing with abnormal customer complaints, we will first learn from the customer about the compatibility information of the faulty module on the switch such as Link, identification, DOM, etc., which is convenient for confirming the failure point, but we often encounter customers who are not clear about which commands to use to view this information. Therefore, this article summarizes the commands to view the compatibility of optical modules in mainstream switches in the current market for your convenience. (Note: the following "[Interface-Id]" indicates the port number of the switch into which the module is inserted)
        1. CISCO
        Let's take CISCO C9500-24Y4C switch as an example, its compatibility commands are as follows.
        ①Link : show interfaces status
        ②Identify : show inventory
        ③DOM : show interfaces transceiver

        2. Huawei
        Let's take Huawei CE6860 switch as an example, its compatibility commands are as follows.
        ①Link:display interface [interface-id]
        ②Identify : display interface [interface-id] transceiver
        ③DOM:display interface [interface-id] transceiver brief

        3. H3C
        Let's take H3C S6820 switch as an example, its compatibility commands are as follows.
        ①Link:>display interfaces [interface-id]
        ②Identify : display transceiver interface [interface-id]
        ③DOM:display transceiver diagnosis interface [interface-id]

        6. Extreme
        Let's take Extreme X690-48x switch as an example, its compatibility commands are as follows.
        ①Link:show ports [interface-id] configuration
        ②Identify : show ports [interface-id] configuration
        ③DOM:show ports [interface-id] transceiver information

        8. Ruijie
        Let's take Ruijie S6510-48VS8CQ switch as an example, its compatibility commands are as follows.
        ①Link:show interfaces [interface-id] status
        ②Identify : show interfaces [interface-id] transceiver
        ③DOM:show interfaces [interface-id] transceiver diagnosis<
