www.dell.com | support.dell.com Parameters unicast [src-card ID [dst-card ID]] multicast [src-card ID] brief (OPTIONAL) Enter the keyword unicast to display Unicast queue statistics. Optionally, enter the source card identification (src-card ID) and the destination card identification (dst-card ID) to display the unicast statistics from the source card to the destination card. Destination card Identification: Range 0 to 13 or RPM (OPTIONAL) Enter the keyword multicast to display only Multicast queue statistics. Optionally, enter the source card identification (src-card ID) to display the multicast statistics from the source card. Default: Both Unicast and Multicast queue statistics are displayed. (OPTIONAL) Enter the keyword brief to display only ingress per link buffering and egress per port buffering statistics. Defaults No default behavior or values Command Modes EXEC EXEC Privilege Command History Version 6.2.1.1 Introduced Usage EtherScale systems display cumulative dropped packets, while TeraScale systems display cumulative Information queued bytes (in KB), cumulative queued packets (in KB), and cumulative dropped packets (in KB). The display area is limited to 80 spaces to accommodate the screen and for optimal readability. Numbers, that is values, are limited to 12 characters. The conventions are detailed in the following table. Table 47-14. Numbering Conventions for show queue statistics ingress Output Value Divide the number by Quotient Display Examples (10^11) - (10^14) 1024 K 12345678901K (10^14) - (10^17) 1024*1024 M 12345678901M > (10^17) 1024*1024*1024 T 12345678901T Note: The show queue statistics command displays Queued Packets and Queued Bytes. The show qos statistics command displays Matched Packets and Matched Bytes. The following example explains how these two displays relate to each other. • 9000 byte size packets are sent from Interface A to Interface B. • The Matched Packets on Interface A are equal to the Queued Packets on Interface B. • Matched bytes on Interface A = matched packets *9000 • Queued bytes on Interface B = queued packets *(9020)-Each packet has an additional header of 20 bytes. 1230 | Quality of Service (QoS)
