show qos info

Use the show qos info command to display QoS-related information for a specified port.

show qos info {runtime | config} {mod_num/port_num}
show qos info config port_type tx | rx

Syntax Description


runtime	Keyword to show the current QoS run time information.
config	Keyword to show the NVRAM setting of QoS.
mod_num /port_num	Number of the module and the port.
port_type	Only valid values for port_type is 2q2t for transmit and 1q4t for receive.
tx	Keyword to specify the transmit drop threshold.
rx	Keyword to specify the receive drop threshold.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

The display of show qos info runtime mod_num/port_num shows both the absolute values and the percentages you specified for the drop thresholds, queue sizes, and WRR. However, the absolute values may not exactly match the percentages specified due to the granularity of permitted settings in hardware.

The number preceding the t in the port-type determines the number of threshold values that the hardware supports. For example, with 2q2t, two thresholds are specified; with 1q4t, four thresholds are specified.

The number preceding the q in the port-type determines the number of the queues that the hardware supports. For example, with 2q2t, two queues are specified; with 1q4t, four queues are specified.

Related Command

set qos

show qos mac-cos

Use the show qos mac-cos command to display the currently configured QoS-related information for the MAC address and VLAN pair.

show qos mac-cos dest_mac [vlan]
show qos mac-cos all


dest_mac	MAC address of the destination host.
vlan	(Optional) Number of the VLAN; valid values are 1 to 1005.
all	Keyword to specify all MAC address and VLAN pairs.

Syntax Description

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guideline

You can enter the show qos mac-cos command to display the currently configured QoS-related information. You can enter the show qos info config to view the NVRAM setting of QoS. This command might be useful to check if the NVRAM setting is different from the hardware setting. For example, if you configure some settings for QoS while QoS is disabled, the setting is saved in NVRAM but the hardware is operating at a different set of parameters.

Example

This example shows how to display currently configured QoS-related information for all MAC address and VLAN pairs:

Console> (enable) show qos mac-cos all
VLAN  Dest MAC            CoS
----  ------------------  ---

show qos statistics

Use the show qos statistics command to display the various QoS-related counters for a specified port.

show qos statistics {mod_num[/port_num]}

Syntax Description


mod_num /port_num	Number of the module and the port (the port number is optional), but the module number is required.

Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guideline

In the show qos statistics output, the Threshold #:Packets dropped field lists each threshold and the number of packets dropped. For example, 1:0 pkt, 2:0 pkts means that threshold 1 and threshold 2 had 0 packets dropped.

Example

This example shows how to display QoS statistics information for module 2, port 1:

Console> (enable) show qos statistics 2/1
On Transmit: Port 2/1 has 2 Queue(s) 2 Threshold(s)
