Finally the substitution replaces every newline with a space on the pattern space (which is the whole file).This is necessary to avoid executing N again, which would terminate the script if there is no more input!). If we are before the last line, branch to the created label $!ba ( $! means not to do it on the last line.Append a newline and next line to the pattern space via N.sed starts by reading the first line excluding the newline into the pattern space.Additional substitutions can be simply appended if needed. This will read the whole file in a loop ( ':a N $!ba), then replaces the newline(s) with a space ( s/\n/ /g). It defaults to macadderss unless otherwise configured.Use this solution with GNU sed: sed ':a N $!ba s/\n/ /g' file The inputs option is a list of comma-delimited fields in the incoming data. Options for format are: cisco, dash, ieee, and none. | `normalize_mac_address(mac)` | lookup mac_vendor_lookup mac OUTPUT mac_vendor, mac_vendor_address, mac_vendor_address2, mac_vendor_country |. The app was tested on Splunk 6.2+ on CentOS Linux 7.1, SUSE Linux Enterprise Server 11.4/12.3, and Ubuntu 16.04. Splunk cmd python SA-NetOps/bin/ieee_oui_parser.py > SA-NetOps/lookups/mac_vendor_lookup.csv Screenshot It's possible to setup more frequent data refresh, by running the following: Note: Lookup data is static, as in, it is refreshed every app release. | inputlookup vlan_inventory | lookup subnet_to_cidr subnet_mask OUTPUT cidr, binary_mask, host_count, usable_hosts | eval cidr_address= network+cidr | outputlookup cidr_network

Once both steps are complated Splunk will automagically begin tagging all src_ip or dest_ip events with the matching environment information. The user should run the search to manually generate the cidr_network lookup once they have loaded all of thier subnet information into the vlan_inventory lookup. Lookup subnet_to_cidr takes another Lookup vlan_inventory as an input argument it performs an exact match to determine the cidr_notation based on subnet_mask. mac field is expected to be normalized per, to help with this effort macro normalize_mac_address is provided. Lookup mac_vendor_lookup takes mac address an input argument it performs a case insensitive "starts with" match on the mac field to determine vendor information.

Documentation around app installation can be found at Getting Started This project is hosted on GitHub, see InstallĪpp installation is simple, and only needs to be present on the search head. Mapping information is obtained from IEEE, found at. Both can be safely hidden without impacting functionality details on hiding an app are described at:

App comes with sample dashboards to showcase how to use both the mac normalization configuration and subnet conversion kit. Additional capabilities such as normalization of MAC address are also provided per Splunk Common Information model. This supporting add-on (SA) for Splunk enables lookup of MAC address field to IEEE registered vendor information and the ability to identify assets by subnet mask.
