adnAtmInterfaceMaxActiveVcVpiBits
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnAtmInterfaceMaxActiveVcVpiBits
OID (numeric): 1.3.6.1.4.1.637.3.1.4.37.1.2.1.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The maximum number of active Virtual Path Identifier (VPI) bits configured for use on this ATM interface, in Virtual Channel (VC) switch mode. The not significant value is 0. Common Name: Max VPI Bits for VCCs
What is adnAtmInterfaceMaxActiveVcVpiBits?
This OID specifies the number of Virtual Path Identifier bits actively used when the interface operates in Virtual Channel switch mode, setting the theoretical maximum number of VPI values. Network planners reference this when designing VC-mode networks to understand the VPI addressing limitations. For example, a value of 8 means 2^8 = 256 different VPI values are available in VC mode.
