Description

File mirroring

Release 7.0.14

 This feature enables the router to copy files and directories automatically from an active RP to a standby RP thus eliminating the manual intervention or the use of EEM scripts.

You can use these commands to enable the file mirroring feature:

  • mirror enable - The /harddisk:/mirror directory is created by default, but file mirroring feature is only enabled by executing the mirror enable command from configuration terminal. Use the show mirror status command to view the status of the mirrored files.

  • mirror enable checksum - The mirror enable checksum command enables MD5 checksum across active to standby RP to check integrity of the files. This command is optional.
