Abstract
A method of detecting error in a data plane of a packet forwarding element that includes a plurality of physical ternary content-addressable memories (TCAMs) is provided. The method configures a first set of physical TCAMs into a first logical TCAM. The method configures a second set of physical TCAMs into a second logical TCAM. The second logical TCAM includes the same number of physical TCAMs as the first logical TCAM. The method programs the first and second logical TCAMs to store a same set of data. The method requests a search for a particular content from the first and second logical TCAMs. The method generates an error signal when the first and second logical TCAMs do not produce a same search results.
