task 8.3 : bandwidth 1536


why does the SG has "bandwidth 1536" on R2 and R3 ?

- why "bandwidth" ?
- and why 1536 ?



  • WFQ requires the bandwidth to be specified. It's used to determine when there is congestion.

    The default bandwidth is 1544 on T1 serial interfaces. That's not the amount available for IP however as it includes 8 bits that are used for signaling. The correct bandwidth available for IP on a T1 interface is 1536. You can also come by this number by multiplying 64 (speed per channel) * 24 (number of channels in a T1) to get 1536.
