CPAM and vCPAA
Scaling guidelines for CPAM and vCPAA
The following section outlines the tested limits for the CPAM component of NFM-P.
Note: All CPAAs monitoring a contiguous network must belong to the same administrative domain.
The scalability of 7701 CPAA Hardware revision 2 and vCPAA is described in the following table.
