Description: The Maximum Transmission Unit size for the various switching descriptors on an interface is updated in real-time by the I3 Stub. In order to increase performance and reduce network traffic, this parameter determines the minimal percentage change of the Maximum Transmission Unit that causes a new LSP to be originated.

What is prvtIsisSysMTUSizePcntge?

This sets the minimum percentage change in the Maximum Transmission Unit of a switching descriptor that must occur before the router originates a new LSP to advertise the change. It rounds out the set of TE percentage-change thresholds that keep MTU flapping from generating excess LSPs.
