Description This command enables interleaving of high priority frames and low-priority frame fragments within a
FR SAP using FRF.12 end-to-end fragmentation.
When this option is enabled, only frames of the FR SAP non expedited forwarding class queues are
subject to fragmentation. The frames of the FR SAP expedited queues are interleaved, with no
fragmentation header, among the fragmented frames. In effect, this provides a behavior like in
MLPPP Link Fragment Interleaving (LFI).
When this option is disabled, frames of all the FR SAP forwarding class queues are subject to
fragmentation. The fragmentation header is however not included when the frame size is smaller than
the user configured fragmentation size. In this mode, the SAP transmits all fragments of a frame
before sending the next full or fragmented frame.
The receive direction of the FR SAP supports both modes of operation concurrently, with and without
fragment interleaving.
The no form of this command restores the default mode of operation.
Default no interleave
