IS2 supports the classified VLAN information which amounts to the outer VLAN info in case of multiple tags. Here are some examples of the tc flower filter operations that are now supported for the IS2 VCAP: - IPv4 Addresses tc filter add dev eth12 ingress chain 8000000 prio 12 handle 12 \ protocol ip flower skip_sw dst_ip 1.0.1.1 src_ip 2.0.2.2 \ action trap - IPv6 Addresses tc filter add dev eth12 ingress chain 8000000 prio 13 handle 13 \ protocol ipv6 flower skip_sw dst_ip 1::1:1 src_ip 2::2:2 \ action trap - IPv4 fragments tc filter add dev eth12 ingress chain 8000000 prio 14 handle 14 \ protocol ip flower skip_sw dst_ip 3.0.3.3 src_ip 2.0.2.2 \ ip_flags frag/nofirstfrag action trap - TCP and UDP portnumbers tc filter add dev eth12 ingress chain 8000000 prio 21 handle 21 \ protocol ip flower skip_sw dst_ip 8.8.8.8 src_ip 2.0.2.2 \ ip_proto tcp dst_port 100 src_port 12000 action trap tc filter add dev eth12 ingress chain 8000000 prio 23 handle 23 \ protocol ipv6 flower skip_sw dst_ip 5::5:5 src_ip 2::2:2 \ ip_proto tcp dst_port 300 src_port 13000 action trap - Layer 3 and Layer 4 protocol info tc filter add dev eth12 ingress chain 8000000 prio 28 handle 28 \ protocol ipv4 flower skip_sw dst_ip 9.0.9.9 src_ip 2.0.2.2 \ ip_proto icmp action trap - VLAN tag info (outer tag) tc filter add dev eth12 ingress chain 8000000 prio 29 handle 29 \ protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 6 \ vlan_ethtype ipv4 action trap tc filter add dev eth12 ingress chain 8000000 prio 31 handle 31 \ protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 5 \ vlan_ethtype ipv6 action trap - TCP flags tc filter add dev eth12 ingress chain 8000000 prio 15 handle 15 \ protocol ip flower skip_sw dst_ip 4.0.4.4 src_ip 2.0.2.2 \ ip_proto tcp tcp_flags 0x2a/0x3f action trap - IP info (IPv4 TOS field) tc filter add dev eth12 ingress chain 8000000 prio 16 handle 16 \ protocol ip flower skip_sw ip_tos 0x35 dst_ip 5.0.5.5 \ src_ip 2.0.2.2 action trap The "protocol all" selection is not supported yet.

This list is then validated against the list of keysets that is currently selected for the lookups (per port) in the VCAP configuration. The Sparx5 IS2 only has one actionset, so there is no actionset matching performed for now.
