Knowledge Base - FAQ

• GRE traffic, which has inner IPv6 and outer IPv4. • Analyzer filter set to detect outer ipv4 TOS, outer ipv4 destination address and inner IPv6 Traffic Class. • However the filter steam and streamblock result didn’t show anything. • Deactivated the inner IPv6 traffic class filter on analyzer, all result shown up. • Also if inner is IPv4 instead of IPv6, he can detect inner ipv4’s TOS, outer ipv4 address and outer ipv4 TOS without any problem.
