spine NPU units, they range from 1-16. In a Card Type (slot), NPUT units are always indexed starting with
the leaf NPU units, and then proceeding to the spine NPU units.
In an NPU unit, the port numbering of backplane local ports starts from the end of the last front-end
local port ID used.
Until Dell Networking OS Release 9.2(0.0), the show commands displayed only the details computed by
the buffer statistics tracking counters for the egress queues. You can use the show hardware stack-
unit <unit-num> buffer unit <unit-num> command to display the buffer statistics and queue
information. You can use the clear hardware stack-unit <unit-num> command to reset the
statistical details associated with high-Gigabit Ethernet ports.
The following commands are enhanced to display the buffer statistics tracking counters for high-Gigabit
backplane ports:
•
show hardware stack-unit 0 buffer unit 0 total-buffer
----- Buffer Details for Unit 0 -----
Used Packet Buffer for the Unit: 0
Current Available Packet Buffer for the Unit: 46080
Is Dynamic Packet Buffer allocate for the unit: TRUE
Dell#
In the preceding sample output, which is a portion of the complete output that is shown when you
run this command, the following information is displayed:
– The shared buffer space that is available to be allotted to the specific port for the corresponding
stack unit.
– The shared buffer space that is in use by the packets
– Whether dynamic packet buffering allocation is activated are displayed.
•
show hardware stack-unit 0 buffer unit {0-5} port all buffer-info—Supports
backplane or high-Gigabit ports for all queues in all ports in a specific unit.
•
show hardware stack-unit 0 buffer unit {0-5} port {1-41} queue {1-14} buffer-
info—Supports backplane HG ports for a specific port and queue in each and every unit.
•
show hardware stack-unit 0 buffer unit {0-5} port {1-41} buffer-info—Supports
backplane high-Gigabit port for switch fabric or spine units for a specific port.
•
show hardware stack-unit 0 buffer unit {0-5} port all queue all buffer-info—
Supports backplane high-Gigabit ports for all queues in all ports in all units.
•
show hardware stack-unit 0 buffer unit {0-5} port {1-41} queue all buffer-
info—Supports backplane high-Gigabit port for switch fabric or spine units for all queues in a specific
port.
• show hardware stack-unit 0 drops unit {0-5} port {1-41}—Supports drop counters for
non-fanout high-Gigabit ports (backplane ports).
