Configuring Global Cnd Settings; Configuring Cnd Settings For An Interface - HP FlexFabric 5700 series Configuration Manual

Configuring global CND settings

Perform this task to assign a switch to a CND identified by the specified CNPV.
After you assign a switch to a CND, the switch can detect congestion for packets within the CND.
You can assign a switch to multiple CNDs by specifying multiple CNPVs for the switch. For example, a
switch can be assigned to CND 1, CND 2, and CND 3 and have an alternate priority of 0 in all three
CNDs. The following table shows priority mappings:
