Link Services CoS on J-series Services Routers

Unlike M-series and T-series platforms, J-series Services Routers support per-bundle queuing on link services (ls) interfaces. Link services interfaces for J-series Services Routers behave the same way as link services IQ interfaces (lsq). (For more information, see Link Services IQ Interfaces Configuration Guidelines.) There are some exceptions, as follows:

• Queue 2 is reserved for voice traffic (LFI) on J-series Services Routers, while all other queues perform fragmentation.
• For FRF.15 on J-series Services Routers, the constituent links bundled on the link services interfaces (ls) require a single scheduler with 25 percent transmission rates and buffer sizes for queues 0 through 3. You should assign this scheduler to each constituent link—in other words, to E1 interfaces and T1 interfaces. However, you can configure customized scheduler maps for each associated ls-fpc/pic/port.logical interface.

For FRF.16 and MLPPP, link services interfaces (ls) on the J-series Services Router work the same way as link services IQ interfaces (lsq) on M-series platforms.
