User Guidelines
NOTE: This command is only available on N40xx series switches.
This command specified in Interface Configuration mode only affects a
single interface, whereas the Global Configuration mode setting is applied to
all interfaces. The Interface Configuration mode command is only available
on platforms that support independent per-port class of service queue
configuration.
At least one, but no more than
n , tcg-id values are specified with this
command. Duplicate tcg-id values are ignored. Each tcg-id value ranges from
0 to (n-1), where n is the total number of TCG supported per interface. The
number n is platform dependent and corresponds to the number of supported
Traffic Class Groups.
When strict priority scheduling is used for a TCG, the minimum bandwidth
setting for the TCG is ignored and packets are scheduled for transmission as
soon as they arrive. A maximum bandwidth setting for the queue, if
configured, serves to limit the outbound transmission rate of a strict priority
TCG queue so that it does not consume the entire capacity of the interface.
If multiple TCGs on the same interface are configured for strict priority
mode, the method of handling their packet transmission, gives preference
among the strict priority TCGs to the one with the highest tcg-id . Strict
priority or weighted scheduling may be configured manually or via DCBX
using the ETS TLVs.
