Chapter2 Catalyst 6500 Series Switch and ROM Monitor Commands show qos info
show qos info
To display QoS-related information for a specified port, use the show qos info command.
show qos info {runtime | config} {mod/port}
show qos info config port_type {tx | rx}
Syntax Description
Defaults This command has no default settings.
Command Types Switch command.
Command Modes Normal.
Usage Guidelines You can enter the show qos info runtime mod/port command to view the currently used values in the
hardware or the show qos info runtime mod/port command to view the values that h ave been configured
administratively (present in NVRAM). The outputs differ when QoS has been disabled. When you
disable QoS, the values set on all the ports are different from the values present in NVRAM. When you
enable QoS, the values in NVRAM are used to program the hardware.
The display of show qos info runtime mod/port 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 letter in the port_type value (for example, 2q2t, 1p2q2t, 1q4t, 1p1q4t, or
1q2t) determines the number of threshold values the hardware supports. For example, with 2q2t, 1q2t
and 1p2q2t, the number of thresholds specified is two; with 1q4t and 1p1q4t, the number of thresholds
specified is four. Due to the granularity of programming the hardware, the values set in hardware will be
close approximations of the values provided.
The number preceding the q letter in the port_type value determines the number of the queues that the
hardware supports. For example, with 2q2t and 1p2q2t, the number of queues specified is two; with 1q4 t
1p1q4t, and 1q2t, the number of queues specified is one. The system defaults for the transmit queues
attempt to keep the maximum latency through a port at a ma ximu m of 10 ms.
runtime Shows the current QoS runtime information.
config Displays NVRAM QoS configuration.
mod/port Number of the module and port.
port_type Port type; valid values are 2q2t, 1p3q1t, 1p2q2t, 1p2q1t for transmit and
1q4t, 1p1q4t, and 1p1q0t, 1p1q8t, and 1q2t for receive. See the “Usage
Guidelines” section for additional information.
tx Displays transmit port information.
rx Displays receive port information.
