It's more of a perspective thing than a 'real' definition.
CIR from the router's perspective is what your target rate is going to be.
CIR from your telco is what your guaranteed rate is going to be (which they
assume to be your target).
In congested networks, if you've enabled the ability and receive a BECN,
your router will back off of that target transmission rate. The MINCIR
comes in from the router's perspective on "go no lower than this threshold"
idea.
Your provider doesn't care what you set for the minimum. :)
Typical configuration would be that your perception of MINCIR is what you
are purchasing as a guaranteed minimum from the provider (so your mincir =
their cir). Your CIR may vary above that based on whatever your
applications and things like that are.
From the lab's perspective, the CIR is your target rate, the mincir (if
needed) is the "don't go below" transmission.

You have to know two different "languages", Cisco and Telco

Hello Group,
Would any please tell the differnence between "mincir" and "cir". That is
when to use each of them.
I worked with Nortel and Hughes FR switches but haven't come across "mincir"
attribute. Is this proprietary to Cisco.
TIA
Guru
