Scale on custom pipeline Instance

• The hardware can match up to four different Groups of match in the custom-pipeline mode.

• The number of groups depends on the match fields in the HASH or TCAM table.

HASH table

• A single hash table can have match fields from any of the above three groups only.

• Based on the number of groups matched, the scale varies.

  • If the hash table is created with match fields from one group, it can hold up to 64k entries.

  • If the hash table is created with match fields from two or three groups, it can hold up to 32k entries.

    NOTE:

    The maximum numbers of flows for 2930F/2930M switches are limited to 16k entries.

TCAM table

• A single tcam table can have match fields from up to four groups. The new group table has more than four groups.

• The scale varies depending on the number of groups.

  • If the tcam table is created with match fields from one group, it can hold up to 8k entries.

  • If the tcam table is created with match fields from two groups, it can hold up to 4k entries

  • If the tcam table is created with match fields from three or four groups, it can hold up to 2k entries
