configuring a full t3 circuit on a 7200 router

Hi,

I was wondering if this is possible on a 7200 router....

I have ordered a full T3 circuit to my ISP.  It is jammed into my 7200 router T3 card.  Is it possible to allocate 12 mb from the 45 to one Ethernet interface and the rest to another Ethernet interface.  Thanks.

Peter

Are you looking to setup a QOS policy so that one Ethernet interface is limited to 12Mb/s max and the other gets 33Mb/s max?

Here's an example of a QOS policy that could be setup to do what I said above:

Interface Serial1/0
 description DS3 Serial Interface
 ip address A.B.C.D 255.255.255.252
 framing c-bit
 service-policy input InputCap
 service-policy output OutputCap
!
Interface FastEthernet0/0
 description Ethernet1 only gets 12 megs
 ip address 192.168.1.1 255.255.255.0
!
Interface FastEthernet0/1
 description Ethernet2 gets 33 megs
 ip address 10.0.0.1 255.255.252.0

Thanks,

I'll give that a try, but can you explain what these lines mean:

police 12000000 1500000 2000000 conform-action transmit exceed-action drop
police 33000000 4125000 6600000 conform-action transmit exceed-action drop
0

Those lines are what actually "police" the bandwidth...

the 12000000 or 33000000 is the standard rate you want to allow in bits per second
the other 2 are a "standard burst rate" and "maximum burst rate" I just threw in a standard recommendation, you can set them to whatever you'd like.

The rest of the line means if the packets conform to those parameters to transmit it... if it goes above those parameters it will drop the packet. That's basically how you get the cap of your 12 megs and 33 megs.
