I want to check a Juniper Switch's port bandwidth usage.

I tried show interfaces, but there is no current bandwidth condition:

admin@Juniper-ex3300-48t# run show interfaces ge-0/1/1
Physical interface: ge-0/1/1, Enabled, Physical link is Up
  Interface index: 281, SNMP ifIndex: 717
  Link-level type: Ethernet, MTU: 1514, MRU: 0, Speed: 1000mbps, Duplex: Full-Duplex, BPDU Error: None,
  MAC-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled, Flow control: Enabled,
  Auto-negotiation: Enabled, Remote fault: Online, Media type: Fiber
  Device flags   : Present Running
  Interface flags: SNMP-Traps Internal: 0x4000
  Link flags     : None
  CoS queues     : 8 supported, 8 maximum usable queues
  Current address: 54:e0:32:fb:a8:74, Hardware address: 54:e0:32:fb:a8:74
  Last flapped   : 2019-08-08 02:30:04 CST (6w4d 10:08 ago)
  Input rate     : 656 bps (1 pps)
  Output rate    : 656 bps (1 pps)
  Active alarms  : None
  Active defects : None
  Interface transmit statistics: Disabled

  Logical interface ge-0/1/1.0 (Index 72) (SNMP ifIndex 718)
    Flags: Up SNMP-Traps 0x40004000 Encapsulation: ENET2
    Input packets : 2281844
    Output packets: 15936
    Protocol eth-switch
      Flags: Trunk-Mode

there only have the Input rate/Output rate.

The Juniper version is:

admin@Juniper-ex3300-48t# run show version
Hostname: Z179-B-GW
Model: ex3300-48t
Junos: 14.1X53-D49.1
JUNOS EX  Software Suite [14.1X53-D49.1]
JUNOS FIPS mode utilities [14.1X53-D49.1]

Just use the command:

show interfaces ge-0/1/1 extensive | match bps

then you can get what you want, it should be like this:

>show interfaces ge-0/1/1 extensive | match bps
  Link-level type: Ethernet, MTU: 1514, MRU: 0, Speed: 1000mbps, Duplex: Full-Duplex, BPDU Error: None,
   Input  bytes  :          17080147150                 1824 bps
   Output bytes  :         128119082354                 4112 bps
        Link mode: Full-duplex, Flow control: Symmetric, Remote fault: OK, Link partner Speed: 1000 Mbps
                              %            bps     %           usec
     Input  bytes  :                    0                    0 bps
     Output bytes  :                    0                    0 bps

Monitor Interface ge-0/1/1

This will let you monitor interface statistics in real time.
