High-Density Gigabit Ethernet Commands—Alpine 3800 and BlackDiamond 6800 Series Only
show ports ingress stats
show ports {<portlist>} ingress stats {detail}
Description
Displays real-time ingress statistics for one or more “3” series ports.
Syntax Description
Default
N/A
Usage Guidelines
The
“3”
series I/O modules support eight ingress QoS profiles (IQP1 - IQP8).
High-priority packets are packets received below the configured ingress committed rate, and
low-priority packets are packets received above the committed-rate.
View these statistics to analyze usage trends and to maximize network efficiency.
If you do not specify the
detail
keyword, the output indicates the following:
• Port Number
• Link Status—The current status of the link. Options are:
— Ready (R): The port is ready to accept a link.
— Active (A): The link is present at this port.
— Disabled (D): The link is disabled at this port.
— Not Present (NP): The link is not present at this port.
• High Priority Bytes—Sum, per port, of the bytes forwarded for received high-priority packets (traffic
received below the committed rate configured for the ingress QoS profile).
• Low Priority Bytes—Sum, per port, of the bytes forwarded for received low-priority packets (traffic
received above the committed rate configured for the ingress QoS profile).
• Received Total Bytes—The total number of bytes that were received by the port.
• Receive Bytes Dropped—Total number of bytes dropped for this port.
• Total Percent Dropped—Percentage of incoming bytes dropped due to oversubscription congestion
or ingress rate limiting. Displayed with a precision of 1/100 of a percent.
• Transmit XOFF—Total number of XOFF flow control packets sent from this port.
If you specify the
detail
keyword, the following additional information is displayed per ingress queue:
• Queue—One of eight ingress queue names for this port.
portlist Specifies one or more slots and ports. May be in the form 2:*, 2:5, 2:6-2:8.
detail Specifies more detailed information per ingress queue.
