Information
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 47-10. Numbering Conventions for show queue egress statistics Output
unicast | multicast (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.
Interface
(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.
brief (OPTIONAL) Enter the keyword brief to display only ingress per link
buffering and egress per port buffering statistics.

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.
