The Cisco Nexus 9000
Series device has a 12-MB buffer memory that divides into a dedicated per port
and dynamic shared memory. Each front-panel port has four unicast queues and
four multicast queues in egress. In the scenario of burst or congestion, each
egress port consumes buffers from the dynamic shared memory.
You can display the
real-time and peak status of the shared buffer per port. All counters are
displayed in terms of the number of cells. Each cell is 208 bytes in size. You
can also display the global level buffer consumption in terms of consumption
and available number of cells.
Note |
Monitoring the
shared buffer on ALE enabled devices is not supported for the port level.
|
Note |
In the examples
shown in this section, the port numbers are Broadcom ASIC ports. The following
example shows how to determine the Broadcom ASIC port for a front panel
interface, where dpid indicates the Broadcom ASIC port 19 and the unit number
indicates the ASIC instance number 0:
switch# show system internal ethpm info interface ethernet 4/7 | inc IF_STATIC_INFO
IF_STATIC_INFO:
port_name=Ethernet4/7,if_index:0x1a180c00,ltl=2587,slot=3,
nxos_port=6,dmod=10,dpid=19,unit=0,queue=16,xbar_unitbmp=0x1 dev_id=223
|
This example shows how
to display the real-time status of the shared buffer per port in egress:
switch(config)# show hardware internal buffer info pkt-stats module 4 instance 0
INSTANCE: 0

Note |
The data/switching
traffic and pool is represented by SP-0. The control traffic to the supervisor
is represented by SP-3.
|
Note |
The
module and
instance
keywords are optional. You can use them to limit the command to show the output
for a specific module, a specific instance, or both. If you do not use these
optional keywords, the command displays the output for all instances across all
modules.

Usage information is
as follows:
-
Total Instant
Usage—Current shared pool buffer usage in terms of the number of cells on a
global basis.
-
Remaining Instant
Usage—The effective free number of cells available on a global basis.
-
Peak/Max Cells
Used—The maximum buffer usage that is seen until the last clear.
-
Switch Cell
Count—Total global shared pool buffer space available in the platform in terms
of the number of cells on a global basis.

to display the real-time status of the shared buffer per port in ingress:

Note |
You can add the
optional
detail keyword
at the end of the command to display all ports, regardless of whether the usage
count is zero. If you do not use this optional keyword, the command displays
the output for nonzero ports only. The port count for the Cisco Nexus 9000
Series switches is different in egress from other Cisco Nexus devices.
Specifically, “UC(OOBFC)” can be ignored.

This example shows how
to clear the system buffer maximum cell usage counter:
switch# clear counters buffers
Max Cell Usage has been reset successfully
This example shows how
to set a buffer utilization threshold for a specific module:
switch(config)# hardware profile buffer info port-threshold module 1 threshold 10
Port threshold changed successfully
Note |
The buffer threshold
feature is not enabled for ports if they have a no-drop class configured (PFC).
|
Note |
The configured
threshold buffer count is checked every 5 seconds against all the buffers used
by that port across all the queues of that port.
|
Note |
You can configure
the threshold percentage configuration for all modules or for a specific
module, which is applied to all ports. The default threshold value is 90% of
the switch cell count of shared pool SP-0. This configuration applies to both
Ethernet (front panel) and internal (HG) ports.
|
Note |
The buffer threshold
feature is not supported for ACI capable device ports.
|
This example shows how
to display the current threshold configuration applied to all ports:
switch(config)# show hardware internal buffer info pkt-stats threshold

Module 5 Instance 0 Port 3 Threshold 90 Cells 25926
Module 5 Instance 0 Port 4 Threshold 90 Cells 25926
Note |
When a port's buffer
usage exceeds the configured/default threshold, a syslog message is generated.
The message rate is limited to one syslog message per minute per port.
|
This example shows how
to display the last five times that the buffer utilization exceeded the
configured threshold value for all ports:
switch(config)# show hardware internal buffer info pkt-stats port-log
