Due to limited resources of X*710 (parser and analyzer configuration tables, number of packet classification types, number of packet types, filters configuration tables, etc.), it's impossible to simultaneously support all protocols/filters required for different parts on network. To enable protocols/filters extensions for X*710, new Admin Command for loading user defined configurations is added. PPP is a format of extend configuration for X*710, it allows user to load user defined configuration to X*710. Actually I have no released doc to share, the documents in my hand are draft and can't be forwarded. > > What are the use cases, what are the benefits of this feature? List of possible use cases for extended X*710 configuration using profiles could include following: Configuring Analyzer/Parser to support new protocols, for example: * IP L2TPv3 tunneling protocol * IPSec ESP/AH protocols * MPLSoGRE, MPLSoUDP tunnels * GTP-C/GTP-U tunnels New PCTYPEs for offloading packet classification to X*710. For example: * new IP Protocol in addition to TCP/UDP/SCTP * new TCP/UDP subtypes, like TCP SYN, TCP FIN * new PCTYPE for tunneled packets like GTP-C, GTP-U New PTYPEs for packets identification, for example: * MAC, MPLS, IP4, UDP * MAC, MPLS, MPLS, IP6, TCP Fixes for NVM configuration, for example: * list of enabled stat counters to improve throughput * parser/analyzer configuration for some corner cases > > And can you please update release notes to announce about added feature?
