Shapers
The PathBuilder S330/S310 supports ten peak rate shapers. The shapers are
separated into ten virtual queue-trunks:
n 4 for the group 1 IMA WAN interface:
n Trunk bulk
n medium
n low1
n low2
n 2 for the AAL5 SAR (Ethernet and V.35/RS-449 packet)
n SAR output
n SAR input
CAUTION: The default configuration is optimized for performance.
n 4 for the OC3/STM-1 interface:
n OC3/STM-1 bulk (MMF or SMF)
n OC3/STM-1 queue 1
n OC3/STM-1 queue 2
n OC3/STM-1 queue 3
n OC3/STM-1 queue 4
