A network system provides network device having a secondary memory that mirrors the content of a primary memory maintaining data structure parameters entries. The integrity of each data structure parameter entry is tested as the entry is output from the primary memory, such as by using a parity test. If an error is detected in the entry, a corresponding entry from the second memory structure is select for use instead of the entry from the primary memory. The corresponding entries in each memory are then flushed, updated, synchronized, or overwritten from the each memory and processing continues using the new entries or other entries from the primary memory. In the rare instance that corresponding entries from both memories exhibit an error, then an error notification is issued. |
