多网口一定要做端口聚合吗？

本帖最后由 downforce 于 2017-9-21 22:26 编辑

东西越来越多了，终于路由器的有线接口不够用了。于是买了个交换机。然后呢这下接口有富裕了，而nas有双网卡，没有端口聚合功能的话把它俩都接交换机上有没有用？还是会出问题？


Both LACP and Static LAGs are covered by 802.3ad standard.
Static was in an "early" release of 802.3ad, LACP in a more recent version.
Neither of them are NETGEAR proprietary protocols, they both in the 802.3ad standard.
That's why on the Datasheet, it's stated "IEEE 802.3ad Link Aggregation: Static LAG". It might be a tiny bit confusing, but it doesn't say LACP anywhere, so it is correct.
As far as I know, no ProSafe Plus / Click Switches from NETGEAR (ending up by an "E") supports LACP LAGs, but most of them support Static LAGs. I'm also pretty it's never gonna be added on those switches as the chip is probably not powerful enough to process hashes as required by LACP.
LACP LAG on NETGEAR switch is IEEE 802.3ad Dynamic Link Aggregation on the Synology.
Static LAG on NETGEAR switch is Balance XOR (IEEE 802.3ad draft v1), this is sometimes called Round-Robin.
原来我买的交换机GS116e V2支持端口聚合，不过不支持新的LACP LAG，只支持静态LAG，NAS里要设置为Balance XOR。

需要两头都支持

普通交换机都不支持的吧, 不过现在很多高端路由器已经支持了, 如果路由器支持的话nas直接接路由器上

没聚合你都接上去还是可以用的
但是带宽不会翻倍
两个网卡会有不同的IP地址独立工作

看情況，靜態聚合不需要其他設備支持，LACP需要

会有几十台设备同时满速连nas吗？单设备机械硬盘撑死也就千兆了

我在想，你nas支持了链路合并把1g变2g，那么连接它的设备也需要能支持合并到2g的速度吧？不然是多设备连接的话，插两条网线两个1g作用是一样的吧？

當然不一樣，兩個千兆滿速連進去的時候，難道還分別用不同IP連？鏈路聚合之後不用自己心煩這種事情不好麼

链路聚合不会增加单线的最大速度，不过多线效果如何我没查到
