Maximum number of NNI links per port | IBM SG24-4817-00 specs

This soft copy for use by IBM employees only.

Each NNI connection requires that a static route be configured so that the routing mechanism is aware of the destination network. The maximum number of static route definitions is 50 per control point.

•Maximum number of NNI links per port

The maximum number of NNI logical links per port is only restricted by the maximum number of VPCs since an NNI logical link needs a unique VPI value to distinguish it from the others. Therefore, the maximum number of NNI logical links per port is 15 on the 25 Mbps ports and 63 on the other ports.

The maximum number of NNI logical liks per 8285 is 64.

Note

Prior to the control point code V1.0.1, static routes could not be defined to nonadjacent clusters. This limitation has been removed.
