From User Exec mode, use the following show commands to monitor and display the T3 interface,
T1 interface, and HDLC serial data channel information:
Monitor channelized T3 interfaces on a slot and port.
host1#show controllers t3 0/1
Monitor a T1 interface.
host1#show controllers t3 0/1:1
Monitor fractional T1 subchannels.
host1#show controllers t3 ft1
Monitor the state of the serial interface or a slot/port.
host1#show controllers t3 serial 0/1
Setting a Baseline
You can set a statistics baseline for serial interfaces,
subinterfaces, and/or circuits using the baseline interface
serial command. Use the delta keyword with the show commands to display
statistics with the baseline subtracted.
Displaying Counters and Time Intervals
Counters and time intervals are MIB statistics,
which are defined in the following specifications:
RFC 2495—Definitions of Managed Objects for the
DS1, E1, DS2 and E2 Interface Types (January 1999)
RFC 2496—Definitions of Managed Objects for the
DS3/E3 Interface Types (January 1999)
The show controllers t3 slot/port all command displays the following information:
T3 current interval counters—Counters for the current
interval
T3 last interval counters—Counters for the previous
interval
T3 24-hour total counters—Cumulative counters for
the last 24 hours or since the interface was started
The last 24 hours of 15-minute reporting intervals (96
intervals)
The show controllers t3 slot/port:channel all command displays the following information:
T1 current interval counters—Counters
for the current interval
T1 last interval counters—Counters for the previous
interval
T1 24-hour total counters—Cumulative counters for
the last 24 hours or since the interface was started
The last 24 hours of 15-minute reporting intervals (96
intervals)
Output Filtering
You can use the output filtering feature of the show command to include or exclude lines of output
based on a text string you specify. See Command Line Interface in JUNOSe System Basics Configuration Guide, for details.
baseline interface serial
Use to set a statistics baseline for serial interfaces.
The router implements the baseline by reading and storing
the statistics at the time the baseline is set and subtracting this
baseline whenever baseline-relative statistics are retrieved.
Use the optional delta keyword with the show
interfaces serial commands to view the baseline statistics.
Use to display data and MIB statistics for a T3 interface
or a T1 channel.
Use the brief keyword to display
the administrative and operational status of all configured T3 interfaces,
or to display abbreviated information for the specified T3 interface.
For definitions of the MIB statistics for a T3 interface,
see RFC 2496—Definitions of Managed Objects for the DS3/E3 Interface
Types (January 1999).
For definitions of the MIB statistics for a T1 channel,
see RFC 2495—Definitions of Managed Objects for the DS1, E1,
DS2 and E2 Interface Types (January 1999).
