    Data Collector Instruction

    1. Specify whether to use Telnet or SSH. The default option “Use Router Profile Setting” will use the Access Method preference specified in the selected router profile entries. You can override this by specifying Telnet only or SSH only. Alternatively, if you choose Telnet - or SSH as alternate, then telnet will be used first to log into a device. Only if that fails, then SSH will be used. Vice versa for SSH - or Telnet as alternate. If necessary, the command used to collect ssh can be edited in /u/wandl/db/command/ssh.cmd.
    2. Check the box for Incremental Data Collection for a live network collection when you do not want to lose or overwrite data from previous collections on the same network.
    3. Check the box for Archive Old Data to store data in /u/wandl/data/collection.archive as a .tar.Z file which can be extracted using the uncompress and tar commands. (Regular collected data is stored in /u/wandl/data/collection/.LiveNetwork/LiveNetwork for the live network, and /u/wandl/data/collection/Default for the offline network. The .Live Network directory is hidden because it should not be modified.) For more details about file organization, refer to Appendix A, Data Repository.
    4. Check the box for “Consolidate with existing planned data” to reuse existing muxloc, nodeparam, and vpn files, etc.to construct the network files. For example, this could include additional info that cannot be derived from the configuration files, such as geographical information of nodes, or links manually added and specified as fixed links. Select also the output directories for any previously run VLAN Discovery or Host Discovery task, to have as fully comprehensive a network as possible.
