Field Description<br />

Copyright © 2012, <strong>Juniper</strong> <strong>Networks</strong>, Inc.<br />

Information about the configuration of the Packet Forwarding Engine:<br />

• Destination slot—FPC slot number.<br />

• PLP byte—Packet Level Protocol byte.<br />

Information about the CoS queue for the physical interface.<br />

• CoS transmit queue—Queue number and its associated user-configured<br />

forwarding class name.<br />

• Bandwidth %—Percentage of bandwidth allocated to the queue.<br />

• Bandwidth bps—Bandwidth allocated to the queue (in bps).<br />

• Buffer %—Percentage of buffer space allocated to the queue.<br />

• Buffer usec—Amount of buffer space allocated to the queue, in microseconds.<br />

This value is nonzero only if the buffer size is configured in terms of time.<br />

• Priority—Queue priority: low or high.<br />

• Limit—Displayed if rate limiting is configured for the queue. Possible values<br />

are none and exact. If exact is configured, the queue transmits only up to the<br />

configured bandwidth, even if excess bandwidth is available. If none is<br />

configured, the queue transmits beyond the configured bandwidth if<br />

bandwidth is available.<br />

Name of the logical interface.<br />

Logical interface index number, which reflects its initialization sequence.<br />

Logical interface SNMP interface index number.<br />

Information about the logical interface. Possible values are described in the<br />

“Logical Interface Flags” section under “Common Output Fields Description”<br />

on page 125.<br />

Encapsulation on the logical interface.<br />

Total number of bytes and packets received and transmitted on the logical<br />

interface. These statistics are the sum of the local and transit statistics. When<br />

a burst of traffic is received, the value in the output packet rate field might briefly<br />

exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this<br />

counter to stabilize.<br />

• Input rate—Rate of bits and packets received on the interface.<br />

• Output rate—Rate of bits and packets transmitted on the interface.<br />

Chapter 16: Channelized OC Interface Operational <strong>Command</strong>s<br />

Statistics for traffic received from and transmitted to the Routing Engine. When<br />

a burst of traffic is received, the value in the output packet rate field might briefly<br />

exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this<br />

counter to stabilize.<br />
