Parameters
age-time: Specifies the aging time for Path MTU in minutes, in the range of 10 to 100.
Usage guidelines
After the path MTU from a source host to a destination host is dynamically determined, the source host sends subsequent packets to the destination host based on this MTU. After the aging time expires:
The dynamic Path MTU is removed.
The source host re-determines a dynamic path MTU through the Path MTU mechanism.
The aging time is invalid for a static Path MTU.
Examples
# Set the aging time for a dynamic Path MTU to 40 minutes.
