Two Ethernet frames must have an interframe gap (IFG) to differentiate two data packets. A device uses the IFG to process a data frame after receiving it and prepares for the receiving of the next data frame. The default IFG on a switch is 12 bytes. You are advised not to change the IFG on an interface, otherwise, packet loss may occur when the interface forwards packets.

You can run the ifg ifg-value command to configure the IFG between Ethernet frames.

Only S5300-X-LI support the IFG.

For the S2300, the ifg command changes the IFG on all the interfaces.
