• The [edit logical-systems
routers.
• The ACX Series routers does not support per-family maximum transmission unit (MTU)
configuration. The MTU applied to family inet gets applied to other families as well, even
though it can be configured though CLI and visible in show interface extensive output. The only
way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet
levels, and let it calculate for each family automatically. MTU values are not limited to 1500
but can range between 256 to 9216.
