Brocade ICX6450-C12-PD的SFP端口一直down:C12只能跑1G,而对端ICX6450-24P默认是10G
一台Brocade ICX6450-C12-PD(已授权10G)的两个SFP端口(F1/F2),不管插Brocade 1000BASE-LR SFP(33211-100)还是10GBASE-SR模块,通过一条5米单模跳线连到ICX6450-24P,都建立不起链路。show media能看到光模块,但接口报告GigabitEthernet1/3/1 is down, line protocol is down。

C12这个型号不管有没有授权,都只支持1G SFP模块,所以10G光模块建立不起链路。
24P那一侧的SFP+端口默认是10G;用interface e 1/2/1, speed-duplex 1000-full, write mem把它强制改成1G,让两端都跑1G。这解决了问题。
