Command Usage
◆
This switch provides more efficient throughput for large sequential data
transfers by supporting Layer 2 jumbo frames on Gigabit and 10 Gigabit
Ethernet ports or trunks of up to 10240 bytes. Compared to standard Ethernet
frames that run only up to 1.5 KB, using jumbo frames significantly reduces the
per-packet overhead required to process protocol encapsulation fields.
Function
Enables support for jumbo frames
