show interface

[stephtchoko]

Good day,

While troubleshooting, we look at interface state by "show interface".

Please how the router calculate the reliability, the load and delay.

If the reliabity is less than 255/255 what does it means ?

Best regards.

My understanding is that the calculation of reliability is based on keepalives sent and received. Any keepalive sent but not received reduces the level of reliability.

The load is calculated by using the actual bits transmitted over the interface in a given period of time and the capacity of the interface (using the default bandwidth if no explicit bandwidth was configured).

The delay is not calculated at all but is a value assigned to the interface to reflect the relative capacity of the interface.

Thank you!

I just found the below calculation :

reliability = number of errors / number of total frames

from : http://www.cisco.com/en/US/products/hw/modules/ps2033/products_tech_note09186a00800d76fb.shtml

reliability is between 0 and 1 so when it becomes near zero, it means it's not reliable link.
