Hello,
Important: This is not a question about the interface config command "load-interval 30".
I have a TCL script that runs in the CLI and extracts via "sh interface <intf>" the input and output rate counters in 5 sec interval.
On Cisco 4k and 800 series routers, it always resulted in new counter readings with the 5 sec interval. -> That's good!
However, it seems to be different on ISR 1000 series routers and at least one Cisco 1009.
There, with a 5 sec interval, I often get identical values on two consecutive queries.
Possibly it is a 10sec interval on these, but I don't know for shure.
Does anyone know the value of this update interval in the different router series / IOS versions?
Does anyone know if it is possible to influence the interval at which the Cisco routers internally update these counters?
To illustrate which counters I mean:
Router1#sh int ten0/0/0 | i t rate
30 second input rate 8075000 bits/sec, 1771 packets/sec
30 second output rate 4962000 bits/sec, 1762 packets/sec
Router1#
<wait 5 (or x?) sec>
Router1#sh int ten0/0/0 | i t rate
....
and so on.
Thanks!
