Show Input or Output rate of Sub-interfaces

[Qi Liu]

Hi Team,

Is there some way to know the input/output rate of sub-interfaces?
When I use "show interface fa0/0.1" , there is nothing related to traffic information.

Many thanks.

router#sh int fa 0/0 | i put rate
  5 minute input rate 4000 bits/sec, 8 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
router#sh int fa 0/0.1
  FastEthernet0/0.1 is up, line protocol is up
  Hardware is Gt96k FE, address is c001.4120.0000 (bia c001.4120.0000)
  Internet address is 1.1.1.1/24
  MTU 1500 bytes, BW 10000 Kbit/sec, DLY 1000 usec,
  reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation 802.1Q Virtual LAN, Vlan ID 1.
  ARP type: ARPA, ARP Timeout 04:00:00
  Last clearing of "show interface" counters never

Hi Qi Liu

As far as im aware there is no separate counters stored for sub-interfaces as below locally on the device but we use applications such as LiveAction that can record data from sub-interfaces through netflow or UIM or Netqos but they all cost money

You could also snmp it to receive it , haven't tried this but there is a separate mib for each sub I would think that's how the some apps pull it when not using netflow

show snmp mib ifmib ifindex

GigabitEthernet0/0/0.1192: Ifindex = 1114

GigabitEthernet0/0/0.6: Ifindex = 82

Hi Mark Malone,

    Thank you for answering the question. SNMP/Netflow are surely good ways to monitor the traffic . And configuring QoS is also a good way .

    It is really a pity sub-interfaces' rate cannot be directly shown by "show interface".

Yes definitely feels like a limitation that could easily be fixed , the traffic is being sent from the router to an app using netflow you would think the router/switch itself could also see the data and provide it , there may be a legitimate reason behind it too TAC may be able to answer that
