可能发错区了,来这里咨询个 Cisco PoE 交换机与 Netgear PD 交换机的兼容性问题

    这是一个创建于 748 天前的主题,其中的信息可能已经有所发展或是发生改变。
    Cisco 的 PoE 协议和 Netgear 的号称都是支持 802.3af 和 802.3at 的

    实际我用 2960L-16PS 给 Netgear 的 GS105PE 供电,供电能识别到,但是网络连接无法识别

    这个有没有什么兼容性的配置参数的= =

    表现就是,端口快速 UP/DOWN 一次,然后显示未链接

    我拔插几次网线的 log:

    这次就是成功协商好的,正常能用- -

    cdp 默认开启,lldp 默认没开,都启用禁用过了,无效

    端口强制 speed 1000 和 duplex full,也无效

    lldp 最大的帮助就是,在小几率能连上的情况下,PD 受电能识别到 30W,没开 lldp 是 15.4W

    可是网络连接还是断的呀还是断的呀!!= =

    各位大大有啥建议么?

    "实际我用 2960L-16PS 给 Netgear 的 GS105PE 供电"
    没有搞错的话,交换机给交换机供电?交换机只能 POE 供电,不能 POE 取电。

    好吧,是我搞错了。还真可以 POE 取电。

    在 cisco 的端口上试一下指定功率,power inline static max 15400

    需要在思科交换机全局启用 LLDP,(config)# lldp run,在用 show power inline 看一下,所在的接口是否支持 Max 30W。如果想 GS105PE 的 1,2 口正常供电,需要 30W 支持。

    我的是 3560CX 连的,工作正常

    hrzhm   2018-01-15 09:56:09 +08:00
    @nbsn 已开启 LLDP,支持 30W,我现在不是供电问题,是端口没有 UP

    poe 交换机给 poe 交换机供电?还有这种操作?
    就算是 at 也才 30W 啊

    hrzhm   2018-01-15 17:45:53 +08:00
    @yingfengi 有,另外小交换机 30W 足够足够了吧

    @hrzhm 是 poe 受电的交换机吧?供电的话,最高才 30W 他怎么给其他设备供。而且多半是 15W 的
