我有一个连接到 4506 交换机的 CPE。接口已启动,但我在 MAC sddes-table 上看不到流量 CPE MAC 地址
我已经更换了电缆、SFP 和端口。现在我有了最小的配置(没有什么,即交换机端口访问)并且还没有 MAC。

SFP 是 1000Base-2BX10-D,我检查了规格。我看到 SFP 的操作范围是 RX:-3 到 -19.5 和 TX:-3 到 -9。当我输入命令时,

Transceiver is internally calibrated.
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.

所以我认为这与光纤链路有关,但数据包计数器正在增加。
添加信息:
由于规格,3M电缆的跳线。问题没有解决。
