www.dell.com | support.dell.com Parameters unicast | multicast Interface brief (OPTIONAL) Enter the keyword multicast to display only Multicast queue statistics. Enter the keyword unicast to display only Unicast queue statistics. Default: Both Unicast and Multicast queue statistics are displayed. (OPTIONAL) Enter one of the following interfaces to display the interface specific queue statistics. • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information. • For a SONET interface, enter the keyword sonet followed by the slot/port information. • Fast Ethernet is not supported. (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 Usage Information Version 6.2.1.1 Introduced for E-Series EtherScale systems display cumulative dropped packets, while TeraScale systems display cumulative 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 numbering conventions are detailed in the table below. Table 42-10. Numbering Conventions for show queue egress statistics 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 outputs 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.
