Output Fields

Table 1 lists the output fields for the show interfaces (ISDN dialer) command. Output fields are listed in the approximate order in which they appear.

Table 1: ISDN Dialer show interfaces Output Fields

Clocking	Reference clock source of the interface.	All levels
Speed	Network speed on the interface.	All levels
Device flags	Information about the physical device.	All levels
Interface flags	Information about the interface.	All levels
Link type	Data transmission type.	detail extensive none
Link flags	Information about the link.	detail extensive none
Physical info	Information about the physical interface.	detail extensive
Hold-times	Current interface hold-time up and hold-time down. Value is in milliseconds.	detail extensive
Current address	Configured MAC address.	detail extensive
Hardware address	MAC address of the hardware.	detail extensive
Alternate link address	Backup link address.	detail extensive
Last flapped	Date, time, and length of time since the interface status changed from down to up.	detail extensive none
Input rate	Input rate in bits per second (bps) and packets per second (pps).	none specified
Output rate	Output rate in bps and pps.	none specified
Statistics last cleared	Time when the statistics for the interface were last set to zero.	detail extensive
Traffic statistics	Number and rate of bytes and packets received and transmitted on the physical interface. Input bytes—Number of bytes received on the interface. Output bytes—Number of bytes transmitted on the interface. Input packets—Number of packets received on the interface. Output packets—Number of packets transmitted on the interface.	detail extensive
Input errors	Errors—Input errors on the interface. Drops—Number of packets dropped by the output queue of the I/O Manager ASIC. Framing errors—Number of packets received with an invalid frame checksum (FCS). Runts—Frames received smaller than the runt threshold. Giants—Frames received larger than the giant threshold. Policed discards—Frames that the incoming packet match code discarded because they were not recognized or were not of interest. Usually, this field reports protocols that the Junos OS does not support. Resource errors—Sum of transmit drops.	extensive
Output errors	Carrier transitions—Number of times the interface has gone from down to up. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and then up, or another problem occurs. If the number of carrier transitions increments quickly, possibly once every 10 seconds, the cable, the remote system, or the interface is malfunctioning. Errors—Sum of outgoing frame aborts and FCS errors. Drops—Number of packets dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet dropped by the ASIC RED mechanism. MTU errors—Number of packets larger than the MTU threshold. Resource errors—Sum of transmit drops.	extensive
Logical Interface
Logical interface	Name of the logical interface.	All levels
Index	Index number of the logical interface (which reflects its initialization sequence).	detail extensive none
SNMP ifIndex	SNMP interface index number for the logical interface.	detail extensive none
Generation	Unique number for use by Juniper Networks technical support only.	detail extensive
Flags	Information about the logical interface. Possible values are described in the “Logical Interface Flags” section under Common Output Fields Description.	All levels
Encapsulation	Encapsulation on the logical interface.	All levels
Dialer	Information about the status and configuration of the dialer interface: State—State of the interface: Active or Inactive. Dial pool—Dial pool name. Dial strings—Dialing number for the ISDN connection. Subordinate interfaces—Associated B-channel interface name and SNMP index number. Activation delay—Length of time (in seconds) to wait before enabling the interface after the primary interface has failed. Deactivation delay—Length of time (in seconds) to wait before disabling the interface after the primary interface is operational. Initial route check delay—Wait period (in seconds) for the software to check if the primary interface is up after the router comes up. The range is from 1 through 300 seconds. The default is 120 seconds. Redial delay—(Available on interfaces configured for ISDN dial-out.) Delay, in seconds, between two successive calls made. The range of values is 2 to 255. The default value is 3. Callback wait period—Time, in seconds, that the dialer waits before it calls back the caller ID. The default value is 5. Load threshold—Bandwidth threshold percentage used for adding interfaces. Another link is added to the multilink bundle when the load reaches the threshold value you set. The range of values is 0 to 100. The default value is 100. Load interval—Interval used to calculate the average load on the network. By default, the average interface load is calculated every 60 seconds.	All levels
Bandwidth	Speed at which the interface is running.	detail extensive none
Input packets	Number of packets received on the logical interface.	None specified
Output packets	Number of packets transmitted on the logical interface.	None specified
Traffic statistics	Total number of bytes and packets received and transmitted on the logical interface. These statistics are the sum of the local and transit statistics. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize. Input bytes—Number of bytes received on the interface. Output bytes—Number of bytes transmitted on the interface. Input packets—Number of packets received on the logical interface. Output packets—Number of packets transmitted on the logical interface	detail extensive
Local statistics	Statistics for traffic received from and transmitted to the Routing Engine. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. It takes awhile (generally, less than 1 second) for this counter to stabilize.	detail extensive
Transit statistics	Statistics for traffic transiting the router. When a burst of traffic is received, the value in the output packet rate field might briefly exceed the peak cell rate. This counter normally stabilizes in less than 1 second.	detail extensive
Keepalive settings	Configured settings for keepalives. interval seconds—Time in seconds between successive keepalive requests. The range is 10 seconds through 32,767 seconds, with a default of 10 seconds. up-count number—Number of keepalive packets a destination must receive to change a link’s status from down to up. The range is 1 through 255, with a default of 1. down-count number—Number of keepalive packets a destination must fail to receive before the network takes a link down. The range is 1 through 255, with a default of 3.	detail extensive none
Keepalive statistics	Information about keepalive packets. (When no level of output is specified, the word “statistics” is not part of the field name and the phrase “last seen” is not displayed.)
