CLI Reference Guide
Use this command to set the Maximum Transmission Unit (MTU) size of IP
packets sent on an interface. Use the no form of this command to restore to the
default setting.
Maximum Transmission Unit of IP packet.
The value range is 512-16383.
The default value of IP MTU is 1500
Interface configuration mode
If an outgoing IP packet from CPU interface exceeds the MTU set for the interface,
software will fragment it before sending out.
Note: Changing the MTU value (with the jumbo frame command) won't affect the IP
MTU value, vice verse is same. Therefore you should care both MTU and IP MTU
sizes to make the system working correctly. For example, if IP MTU is larger than
MTU at the egress port, the packet larger than MTU but less than IP MTU may be
dropped by the egress port.
Use show ipif to see the current setting of IP MTU
Set the IP MTU of System (vlan 1) interface to 800 bytes:
