還有一種 Super jumbo frames 可支援到 64000 bytes.雖然 Jumbo frame 可以讓網路效能提昇但是問題來了,並不是每一個 switch 或是網卡都支援 Jumbo frame.所以到頭來 frame 還是會被切割成較小的 frame.至於你要看 switch 或是網卡有沒有支援 Jumbo frame.在 ping 的時候加入參數(-s) 指定資料大小. [root@...
开启/关闭巨帧报文( Jumbo Frame) 转发功能。该功能默认为开启状态。 开启该功能后,对小于等于9216字节的报文,系统可以进行如下转发处理: 对于小于出接口MTU值的IPv4/IPv6报文,直接转发; 对于大于出接口MTU值的IPv4报文,分片转发; 对于大于出接口MTU值的IPv6报文,向发送报文的源节点发送“ICMPv6 Packet Too Big”...
On UniFi Switches and Gateways, the typical MTU size is 9216 bytes when using Jumbo Frames. This applies to all devices with the exception of the following: USG:9000 bytes USG-Pro:9000 bytes Frequently Asked Questions 1. On which devices should I use Jumbo Frames? 2. How can I enable Ju...
The default MTU size is 9216 bytes after you enable jumbo frame support on the individual port. However, an Application Specific Integrated Circuit (ASIC) limitation requires that you limit the MTU size to 8092 bytes on these 10/100-based line cards: WS-X6248-RJ-45 WS-X6248A-RJ-45 WS-...

9000Bytes is generally accepted as the maximum size for a jumbo frame, however, I’ve seen some Cisco switches with MTUs of 9216 Bytes. Why use jumbo frames? It’s a case of getting maximum bang for the buck. Processing overhead is proportional to the number of frames; so if you can...
If jumbo frames are used, ensure that the UCS and storage target, as well as all of the network equipment between, are able and configured in order to support the larger frame size. This means that the jumbo MTU must be configured end-to-end (initiator to target) in ...
