MTU
MTU/Maximum Transfer Unit
MTU is the maximum size of data that can be sent on a network at one time. The MTU value differs for each physical medium.
Examples
- MTU of Ethernet ---> 1500 bytes
- MTU of Optical Fiber (FDDI) ---> 4352 bytes
In the AG10/AR10 series, the MTU value of each interface can be checked from amsh.
