asa sub interface utilization

ring zer0 — Fri, 21 Feb 2020 15:41:18 GMT

Following is the interface utilization of a non-trunk layer 3 interface

  Traffic Statistics for "test":
        7182339 packets input, 447613596 bytes
        7788763 packets output, 431054764 bytes
        27 packets dropped
      1 minute input rate 0 pkts/sec,  13 bytes/sec
      1 minute output rate 0 pkts/sec,  13 bytes/sec
      1 minute drop rate, 0 pkts/sec
      5 minute input rate 0 pkts/sec,  13 bytes/sec
      5 minute output rate 0 pkts/sec,  13 bytes/sec
      5 minute drop rate, 0 pkts/sec

Now when I try to get a stats for a trunk interface or a sub interface I dont see 1 minute and 5 minute data. Is there a limitation in ASA 9.1(5) which restricts the interface utilization data on trunk and sub interfaces?

For reference this is what I get when checking utilization of these interfaces

On the ASA this information is not under the interface. Instead use the following command

show traffic

Here you will see 1 minute and 5 minute rates
