HSP

MMU HSP hierarchy

HSP

Show the MMU HSP (hierarchical scheduler) tree of each port: scheduler nodes, queues, weights and modes. HSP is the scheduler of the Trident 2 family and some smaller chips. On Trident 3 hsp prints nothing, with or without a port bitmap, and returns without an error. Use show soc_is to see which chip family the unit reports.

The only option is PortBitMap=<pbmp> (pbm), which defaults to all ports. Any other word prints hsp: Error: Unknown option: <word>. On chips where HSP does not apply, the command may print HSP command not supported on this device. The SDK’s own techsupport basic and techsupport mmu run hsp.

Read-only.
