The mark-clp command assigns a value of 0 or 1 to the ATM CLP bit for packets
conforming to the current classifier control list.
Modules on E-series routers support classifying
and marking of the ATM CLP bit according to the following rules:
Modules on E120 and E320 routers support classifying of
the ATM CLP bit only for frame-based interfaces (ATM Adaptation Layer
5 [AAL5] encapsulation), but not for individual ATM cells (ATM Adaptation
Layer 0 [AAL0] encapsulation). In this case, if the CLP bit in any
cell in the frame has a value of 1, the router treats the reassembled
AAL5 frame as if it also had a CLP value of 1.
Modules on E120 and E320 routers support marking of the
ATM CLP bit on frame-based interfaces. In this case, every cell of
the segmented frame leaves the router with the same CLP value.
Modules on ERX-7xx models, ERX-14xx models, and the ERX-310
router support classifying and marking of the ATM CLP bit for individual
ATM cells (AAL0 encapsulation), but not for frame-based interfaces
