Cisco Systems OL-10426-01 manual Link Load Report

Chapter 6 NMT Reports

Link Load Report

The Link Load report displays the load resources on each link in the network, based on the static load model.

In the example below, den-sea is a cell based link where the bandwidth is 92% utilized. This link contains 80000 cells for CBR ATM traffic, 7515 cells of frame relay, and has a statistical reserve of 600, which is not included in the total. There are 55 PVCs on the first link.

The second link, nyd-pit, uses only 6% of the bandwidth, but has reached the maximum number of PVC's allowed on the link. Note that this is a packet based trunk, as the units are pps.

The third link, (lax-pit) is a T3 cell based trunk on a BTM card. The units displayed are packets because the constraint on this link is the number of packets that can be received by the IGX bus.

The fourth link, (lax-nyd) is also a cell based trunk. For this link, both the packet load and the cell load are listed because in this case the cell load is the constraint. This is because the combine time outs are set low so most voice and data cells contain only one packet. If the link is partitioned for both AutoRoute and PNNI, the usage of each is displayed.

Note The link load report has a DBF output format.
