Which of the following commands will configure the maximum transmission unit size of a fast Ethernet interface?
A. set interfaces fe-0/0/0 unit 0 ethernet-options mtu 1200
B. set interfaces fe-0/0/0 mtu 1200
C. set interfaces fe-0/0/0 unit 0 mtu 1200
D. set interfaces fe-0/0/0.0 mtu 1200
Example 1: Reset the MTU size to 1492 at the fe-0/0/2 interface.
[edit]
user@srx# set interfaces fe-0/0/2 unit 0 family inet mtu 1492
Example 2: To change the family ISO MTU to 1492 use the following command:
Juniper# set interfaces ge-1/0/2 unit 0 family iso mtu 1492
