It is primarily used for debugging and testing networks. It can be edited and inspected with the following commands: iwpriv ethX bt_reset iwpriv ethX bt_add <mac_address> iwpriv ethX bt_del <mac_address> iwpriv ethX bt_list <id> FWT Commands: The forwarding table (FWT) is a feature used to manage mesh network routing in the firmware. The FWT is essentially a routing table that associates a destination mac address (da) with a next hop receiver address (ra). The FWT can be inspected and edited with the following iwpriv commands, which are described in greater detail below. Eventually, the table will be automatically maintained by a custom routing protocol. NOTE: FWT commands replace the previous DFT commands. What were the DFT commands?, you might ask. They were an earlier API to the firmware that implemented a simple MAC-layer forwarding mechanism. In the unlikely event that you were using these commands, you must migrate to the new FWT commands which can be used to achieve the same functionality. iwpriv ethX fwt_add [parameters] iwpriv ethX fwt_del [parameters] iwpriv ethX fwt_lookup [parameters] iwpriv ethX fwt_list [parameters] iwpriv ethX fwt_list_route [parameters] iwpriv ethX fwt_list_neigh [parameters] iwpriv ethX fwt_reset [parameters] iwpriv ethX fwt_cleanup iwpriv ethX fwt_time MESH Commands: The MESH commands are used to configure various features of the mesh routing protocol.

Usage: iwpriv ethX bcninterval 100 (set adhoc beacon interval to 100) iwpriv ethX bcninterval (get adhoc beacon interval) fwt_add This command is used to insert an entry into the FWT table. The list of parameters must follow the following structure: iwpriv ethX fwt_add da ra [metric dir ssn dsn hopcount ttl expiration sleepmode snr] The parameters between brackets are optional, but they must appear in the order specified. For example, if you want to specify the metric, you must also specify the dir, ssn, and dsn but you need not specify the hopcount, expiration, sleepmode, or snr. Any unspecified parameters will be assigned the defaults specified below. The different parameters are:- da -- DA MAC address in the form 00:11:22:33:44:55 ra -- RA MAC address in the form 00:11:22:33:44:55 metric -- route metric (cost: smaller-metric routes are preferred, default is 0) dir -- direction (1 for direct, 0 for reverse, default is 1) ssn -- Source Sequence Number (time at the RA for reverse routes. Default is 0) dsn -- Destination Sequence Number (time at the DA for direct routes. Default is 0) hopcount -- hop count (currently unused, default is 0) ttl -- TTL (Only used in reverse entries) expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry, default is 0) sleepmode -- RA's sleep mode (currently unused, default is 0) snr -- SNR in the link to RA (currently unused, default is 0) The command does not return anything. fwt_del This command is used to remove an entry to the FWT table. The list of parameters must follow the following structure: iwpriv ethX fwt_del da ra [dir] where the different parameters are:- da -- DA MAC address (in the form "00:11:22:33:44:55") ra -- RA MAC address (in the form "00:11:22:33:44:55") dir -- direction (1 for direct, 0 for reverse, default is 1) The command does not return anything. fwt_lookup This command is used to get the best route in the FWT table to a given host. The only parameter is the MAC address of the host that is being looked for. iwpriv ethX fwt_lookup da where:- da -- DA MAC address (in the form "00:11:22:33:44:55") The command returns an output string identical to the one returned by fwt_list described below. fwt_list This command is used to list a route from the FWT table. The only parameter is the index into the table. If you want to list all the routes in a table, start with index=0, and keep listing until you get a "(null)" string. Note that the indicies may change as the fwt is updated. It is expected that most users will not use fwt_list directly, but that a utility similar to the traditional route command will be used to invoke fwt_list over and over. iwpriv ethX fwt_list index The output is a string of the following form: da ra metric dir ssn dsn hopcount ttl expiration sleepmode snr where the different fields are:- da -- DA MAC address (in the form "00:11:22:33:44:55") ra -- RA MAC address (in the form "00:11:22:33:44:55") metric -- route metric (cost: smaller-metric routes are preferred) dir -- direction (1 for direct, 0 for reverse) ssn -- Source Sequence Number (time at the RA for reverse routes) dsn -- Destination Sequence Number (time at the DA for direct routes) hopcount -- hop count (currently unused) ttl -- TTL (only used in reverse entries) expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry) sleepmode -- RA's sleep mode (currently unused) snr -- SNR in the link to RA (currently unused) fwt_list_route This command is used to list a route from the FWT table. The only parameter is the route ID. If you want to list all the routes in a table, start with rid=0, and keep incrementing rid until you get a "(null)" string. This function is similar to fwt_list. The only difference is the output format. Also note that this command is meant for debugging. It is expected that users will use fwt_lookup and fwt_list. One important reason for this is that the route id may change as the route table is altered. iwpriv ethX fwt_list_route rid The output is a string of the following form: da metric dir nid ssn dsn hopcount ttl expiration where the different fields are:- da -- DA MAC address (in the form "00:11:22:33:44:55") metric -- route metric (cost: smaller-metric routes are preferred) dir -- direction (1 for direct, 0 for reverse) nid -- Next-hop (neighbor) host ID (nid) ssn -- Source Sequence Number (time at the RA for reverse routes) dsn -- Destination Sequence Number (time at the DA for direct routes) hopcount -- hop count (currently unused) ttl -- TTL count (only used in reverse entries) expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry) fwt_list_neigh This command is used to list a neighbor from the FWT table. The only parameter is the neighbor ID. If you want to list all the neighbors in a table, start with nid=0, and keep incrementing nid until you get a "(null)" string. Note that the nid from a fwt_list_route command can be used as an input to this command. Also note that this command is meant mostly for debugging. It is expected that users will use fwt_lookup. One important reason for this is that the neighbor id may change as the neighbor table is altered. iwpriv ethX fwt_list_neigh nid The output is a string of the following form: ra sleepmode snr references where the different fields are:- ra -- RA MAC address (in the form "00:11:22:33:44:55") sleepmode -- RA's sleep mode (currently unused) snr -- SNR in the link to RA (currently unused) references -- RA's reference counter fwt_reset This command is used to reset the FWT table, getting rid of all the entries. There are no input parameters. iwpriv ethX fwt_reset The command does not return anything. fwt_cleanup This command is used to perform user-based garbage recollection. The FWT table is checked, and all the entries that are expired or invalid are cleaned. Note that this is exported to the driver for debugging purposes, as garbage collection is also fired by the firmware when in space problems. There are no input parameters. iwpriv ethX fwt_cleanup The command does returns the number of invalid/expired routes deleted. fwt_time This command returns a card's internal time representation. It is this time that is used to represent the expiration times of FWT entries. The number is not consistent from card to card; it is simply a timer count. The fwt_time command is used to inspect the timer so that expiration times reported by fwt_list can be properly interpreted. iwpriv ethX fwt_time mesh_get_ttl The mesh ttl is the number of hops a mesh packet can traverse before it is dropped. This parameter is used to prevent infinite loops in the mesh network. The value returned by this function is the ttl assigned to all mesh packets. Currently there is no way to control the ttl on a per packet or per socket basis. iwpriv ethX mesh_get_ttl mesh_set_ttl ttl Set the ttl. The argument must be between 0 and 255. iwpriv ethX mesh_set_ttl <ttl> ========================= ETHTOOL ========================= Use the -i option to retrieve version information from the driver. # ethtool -i eth0 driver: libertas version: COMM-USB8388-318.p4 firmware-version: 5.110.7 bus-info: Use the -e option to read the EEPROM contents of the card. Usage: ethtool -e ethX [raw on|off] [offset N] [length N] -e retrieves and prints an EEPROM dump for the specified ethernet device. When raw is enabled, then it dumps the raw EEPROM data to stdout. The length and offset parameters allow dumping cer- tain portions of the EEPROM. Default is to dump the entire EEP- ROM. # ethtool -e eth0 offset 0 length 16 Offset Values ------ ------ 0x0000 38 33 30 58 00 00 34 f4 00 00 10 00 00 c4 17 00 ======================== DEBUGFS COMMANDS ======================== those commands are used via debugfs interface =========== rdmac rdbbp rdrf These commands are used to read the MAC, BBP and RF registers from the card. These commands take one parameter that specifies the offset location that is to be read. This parameter must be specified in hexadecimal (its possible to preceed preceding the number with a "0x"). Path: /debugfs/libertas_wireless/ethX/registers/ Usage: echo "0xa123" > rdmac ; cat rdmac echo "0xa123" > rdbbp ; cat rdbbp echo "0xa123" > rdrf ; cat rdrf wrmac wrbbp wrrf These commands are used to write the MAC, BBP and RF registers in the card. These commands take two parameters that specify the offset location and the value that is to be written. This parameters must be specified in hexadecimal (its possible to preceed the number with a "0x"). Usage: echo "0xa123 0xaa" > wrmac echo "0xa123 0xaa" > wrbbp echo "0xa123 0xaa" > wrrf sleepparams This command is used to set the sleepclock configurations Path: /debugfs/libertas_wireless/ethX/ Usage: cat sleepparams: reads the current sleepclock configuration echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration. where: p1 is Sleep clock error in ppm (0-65535) p2 is Wakeup offset in usec (0-65535) p3 is Clock stabilization time in usec (0-65535) p4 is Control periodic calibration (0-2) p5 is Control the use of external sleep clock (0-2) p6 is reserved for debug (0-65535) subscribed_events The subscribed_events directory contains the interface for the subscribed events API. Path: /debugfs/libertas_wireless/ethX/subscribed_events/ Each event is represented by a filename. Each filename consists of the following three fields: Value Frequency Subscribed To read the current values for a given event, do: cat event To set the current values, do: echo "60 2 1" > event Frequency field specifies the reporting frequency for this event. If it is set to 0, then the event is reported only once, and then automatically unsubscribed. If it is set to 1, then the event is reported every time it occurs. If it is set to N, then the event is reported every Nth time it occurs. beacon_missed Value field specifies the number of consecutive missing beacons which triggers the LINK_LOSS event. This event is generated only once after which the firmware resets its state. At initialization, the LINK_LOSS event is subscribed by default. The default value of MissedBeacons is 60. failure_count Value field specifies the consecutive failure count threshold which triggers the generation of the MAX_FAIL event. Once this event is generated, the consecutive failure count is reset to 0. At initialization, the MAX_FAIL event is NOT subscribed by default. high_rssi This event is generated when the average received RSSI in beacons goes above a threshold, specified by Value. low_rssi This event is generated when the average received RSSI in beacons goes below a threshold, specified by Value. high_snr This event is generated when the average received SNR in beacons goes above a threshold, specified by Value. low_snr This event is generated when the average received SNR in beacons goes below a threshold, specified by Value. extscan This command is used to do a specific scan. Path: /debugfs/libertas_wireless/ethX/ Usage: echo "SSID" > extscan Example: echo "LINKSYS-AP" > extscan To see the results of use getscantable command. getscantable Display the current contents of the driver scan table (ie. get the scan results). Path: /debugfs/libertas_wireless/ethX/ Usage: cat getscantable setuserscan Initiate a customized scan and retrieve the results Path: /debugfs/libertas_wireless/ethX/ Usage: echo "[ARGS]" > setuserscan where [ARGS]: chan=[chan#][band][mode] where band is [a,b,g] and mode is blank for active or 'p' for passive bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan ssid="[SSID]" specify a SSID filter for the scan keep=[0 or 1] keep the previous scan results (1), discard (0) dur=[scan time] time to scan for each channel in milliseconds probes=[#] number of probe requests to send on each chan type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any) Any combination of the above arguments can be supplied on the command line. If the chan token is absent, a full channel scan will be completed by the driver. If the dur or probes tokens are absent, the driver default setting will be used. The bssid and ssid fields, if blank, will produce an unfiltered scan. The type field will default to 3 (Any) and the keep field will default to 0 (Discard). Examples: 1) Perform an active scan on channels 1, 6, and 11 in the 'g' band: echo "chan=1g,6g,11g" > setuserscan 2) Perform a passive scan on channel 11 for 20 ms: echo "chan=11gp dur=20" > setuserscan 3) Perform an active scan on channels 1, 6, and 11; and a passive scan on channel 36 in the 'a' band: echo "chan=1g,6g,11g,36ap" > setuserscan 4) Perform an active scan on channel 6 and 36 for a specific SSID: echo "chan=6g,36a ssid="TestAP"" > setuserscan 5) Scan all available channels (B/G, A bands) for a specific BSSID, keep the current scan table intact, update existing or append new scan data: echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan 6) Scan channel 6, for all infrastructure networks, sending two probe requests. Keep the previous scan table intact. Update any duplicate BSSID/SSID matches with the new scan data: echo "chan=6g type=1 probes=2 keep=1" > setuserscan All entries in the scan table (not just the new scan data when keep=1) will be displayed upon completion by use of the getscantable ioctl. ==============================================================================
