What is the config for this interface? What are the sh controller commands displaying?

Here is the config interface Serial0/0 ip address 206.XXX.XXX.XXX 255.255.255.252 ip access-group 101 in ip access-group 102 out ip nat outside no ip mroute-cache

Hi,

You don't have to worry about that value (unless you want to tune this for QoS implmenetation). A 25% of "bandwidth" is reserved in such a way that you can't allocate it to RSVP, other QoS features (i.e. Class bandwidth/priority). This is a safeguard for traffic overhead and routing protocol traffic not to be starved if you "reserved" the 100% bandwidth to user traffic. Note that now you can already use your whole "pipe", you are not limited to

1158Kbps

You can tune the value using "max-reserved-bandwidth" interface command

Probably I haven't expressed myself well, so you should see some real documentation about this.

Regards, Gabriele
