Configuring the MP endpoint descriptor

When MP is configured by using a VT interface, an MP endpoint makes link binding decisions based on the remote endpoint descriptors. It assigns the links that receive the same endpoint descriptor to the same bundle. To avoid incorrect link binding on a VT interface, make sure the link descriptors used by different devices are unique. You must re-configure an endpoint descriptor for a device if the default endpoint descriptor (device name) cannot uniquely identify the MP bundle at the remote end.

When MP is configured by using an MP-group interface, the negotiating endpoints do not base their binding decisions on the endpoint descriptor. By default, the endpoint descriptor of an interface in an MP-group is the MP-group interface name. When you configure an endpoint descriptor for the interface, the configured MP endpoint descriptor takes effect.

If the endpoint descriptor exceeds 20 bytes, the first 20 bytes are taken as the endpoint descriptor.
