Post-auxiliary Table Specifications

Name

None

Flow table name, which must comply with the DSL naming requirements.

Quantity

0 to 4

The total number of pre-auxiliary tables and post-auxiliary tables must be less than or equal to 4. Among them, both exact and fuzzy auxiliary tables are limited to a maximum of 2 each.

This specification is used as a constraint. The programming framework does not enforce mandatory validation. A configuration that exceeds this specification is subject to the results of resource resolution.

Types

Post-auxiliary table

Supports user declaration and stage-based division.

Keys

• rte_eth_hdr_t
• rte_vlan_hdr_t
• rte_ipv4_hdr_t
• rte_ipv6_hdr_t
• rte_tcp_hdr_t
• rte_udp_hdr_t
• rte_icmp_hdr_t
• rte_icmp6_hdr_t
• rte_vxlan_hdr_t
• rte_port_id_hdr_t
• rte_geneve_hdr_t
• Custom headers

Different tables support different keys, including DPDK standard headers and custom headers. The structures supported by the DPDK standard are defined in built-in header files that are not user-modifiable.

Action

rte_count

This action is used for counting.

Matching mode

Exact and fuzzy

Classification by matching mode.

Number of entries (size)

512 (recommended)

The programming framework does not enforce mandatory validation. A configuration that exceeds the recommended value is subject to the results of resource resolution.

Key size

Exact auxiliary table: 16 bytes

Fuzzy auxiliary table: 80 bytes

If a key does not reach the upper limit, it will be padded to the upper limit.

Aging time

0

The aging function is not supported.
