Field Description<br />

• Errors—Input errors on the interface.<br />

• Drops—Number of packets dropped by the output queue of the I/O Manager<br />

ASIC.<br />

• Framing errors—Number of packets received with an invalid frame checksum<br />

(FCS).<br />

• Runts—Frames received smaller than the runt threshold.<br />

• Giants—Frames received larger than the giant threshold.<br />

• Policed discards—Frames that the incoming packet match code discarded<br />

because they were not recognized or were not of interest. Usually, this field<br />

reports protocols that the <strong>Junos</strong> <strong>OS</strong> does not support.<br />

• Resource errors—Sum of transmit drops.<br />

• Carrier transitions—Number of times the interface has gone from down to up.<br />

This number does not normally increment quickly, increasing only when the<br />

cable is unplugged, the far-end system is powered down and then up, or<br />

another problem occurs. If the number of carrier transitions increments quickly,<br />

possibly once every 10 seconds, the cable, the remote system, or the interface<br />

is malfunctioning.<br />

• Errors—Sum of outgoing frame aborts and FCS errors.<br />

• Drops—Number of packets dropped by the output queue of the I/O Manager<br />

ASIC. If the interface is saturated, this number increments once for every<br />

packet dropped by the ASIC RED mechanism.<br />

• MTU errors—Number of packets larger than the MTU threshold.<br />

• Resource errors—Sum of transmit drops.<br />

Name of the logical interface.<br />

Index number of the logical interface (which reflects its initialization sequence).<br />

SNMP interface index number for the logical interface.<br />

Unique number for use by <strong>Juniper</strong> <strong>Networks</strong> technical support only.<br />

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

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