Configuring Maximum Transition Unit
Maximum transmission unit (MTU) defines the largest size of the packet that can be transmitted as a single entity through the port. The size of the MTU dictates the amount of data that can be transmitted in bytes over a network.
Reference
Command | mtu <mtu val> |
Description | Configure MTU in bytes |
Parameters | Mtu value (MAX: 9100) |
Mode | INTERFACE |
Example
pbnoscli# configure terminal
pbnoscli(config)# interface ethernet Ethernet1/1
pbnoscli(config-if)# mtu
<mtuval> Mtu value (1..9100)
pbnoscli(config-if)# mtu 1600
pbnoscli(config-if)# You can verify the configuration by using the command(s) below:
