Description

Use the mmtu command to display, add, and delete maximum transfer unit (MTU) values to the list of potential path MTU values. Path MTU discovery uses the list of potential path MTU values to detect the path MTU. The list of potential path MTU values is only used when there are routers in the path that do not comply with RFC 1191. The user must have administrative authority to add or delete MTU values.
