I have a router in my new network that is confusing me. It is an old 2610 with a singe Ethernet inerface (NOT FASTethernet)and a Serial interface. I know that ethernet is a 10Mbps link, why would someone have the statment 'bandwidth 10000' on the interface?
ip address 10.X.X.X 255.255.0.0
ip access-group 105 in
ip access-group 105 out
The interface connects to a 10/100/1000 interface on a 4006 that is configured for a speed of 10. If anyone has seen some crazyness like this and can shed some light it would be very helpfull.
The bandwidth command need not always represent the actual bandwidth.It is a way of providing more administrtive control for the routing protocols and QoS mechanisms.IOS respects the bandwidth command configued when it calculates the metric for a routing protocol.(Say eigrp).Similaly Qos decisions can be influenced with configured bandwidth values.
Hope this clarifies.
