Looking through the Cisco ASR (was Starent) Dictionaries and it seems SN-Rulebase is commented out. As per: http://www.cisco.com/c/dam/en/us/td/docs/wireless/asr_5000/8_x_9-0/OL-22955-... SN-Rulebase When the session is active charging enabled, Rulebase name will specify one of the pre configured ECSv2 rulebases in active charging subsystem. Type 26 Vendor ID 8164 VSA Type 250 Length 1–64 Value String Any reason why it's commented out as 249, rather than 250? Had a search through the mail archives but nothing apart from http://lists.freeradius.org/pipermail/freeradius-users/2010-July/047555.html Which also lists VSAs 1001 - 1040 which is in the Cisco docs but not in the dictionary. So.. Just push a patch for this or is there a reason why it was missing? Cheers Peter
