For these flags, refer to the Makefile. +Refer to the README file for more information on how to run PROX for specific use cases. + +:: + + Usage: ./build/prox [-f CONFIG_FILE] [-l LOG_FILE] [-p] [-o DISPLAY] [-v] [-a|-e] [-m|-s|-i] [-n] [-w DEF] [-q] [-k] [-d] [-z] [-r VAL] [-u] [-t] + -f CONFIG_FILE : configuration file to load, ./prox.cfg by default + -l LOG_FILE : log file name, ./prox.log by default + -p : include PID in log file name if default log file is used + -o DISPLAY: Set display to use, can be 'curses' (default), 'cli' or 'none' + -v verbosity : initial logging verbosity + -a : autostart all cores (by default) + -e : don't autostart + -n : Create NULL devices instead of using PCI devices, useful together with -i + -m : list supported task modes and exit + -s : check configuration file syntax and exit + -i : check initialization sequence and exit + -u : Listen on UDS /tmp/prox.sock + -t : Listen on TCP port 8474 + -q : Pass argument to Lua interpreter, useful to define variables + -w : define variable using syntax varname=value + takes precedence over variables defined in CONFIG_FILE + -k : Log statistics to file "stats_dump" in current directory + -d : Run as daemon, the parent process will block until PROX is not initialized + -z : Ignore CPU topology, implies -i + -r : Change initial screen refresh rate. If set to a lower than 0.001 seconds, + screen refreshing will be disabled + +CONFIGURATION FILE FORMAT +------------------------- +The configuration file is divided into multiple sections, each of which is used to define some parameters and options. +Sections are created using the [section name] syntax. The list of sections, where # represents an integer, is as follows: + +:: + + [eal options] + [port #] + [variables] + [defaults] + [global] + [core #] + +In each section, entries are created using the key=value syntax. +Comments are created using the ; symbol: all characters from the ; +symbol to the end of line are ignored. A # symbol at the beginning of the section name comments +the whole section out: all entries in the section are treated as comments and are ignored. For example: + +:: + + [#core 1] + ; this is a comment + parameter name=parameter value ; this entry is ignored because the section is commented out + +* [EAL OPTIONS]: The following parameters are supported: + +:: + + -m ; Specifies the amount of memory used. If not provided, all hugepages will be used. + -n ; Specifies the number of memory channels. Use -n4 for latest Intel Xeon based platforms + -r ; Specifies the number of memory ranks. + eal ; Specifies DPDK EAL extra options. Those options will be passed blindly to DPDK. + +* [PORT #]: DPDK ports are usually referenced by their port_id, i.e. an integer starting from 0. + Using port_id in the configuration file is tedious, since the same port_id can appear at + different places (rx port, tx port, routing tables), and those ports might change (e.g. if cables are swapped). + In order to make the configuration file easier to read and modify, DPDK ports are given a name with the name= option. + The name serves as the reference, and in addition, it will show up in the display at runtime. + +:: + + PARAMETER EXAMPLE DESCRIPTION + ---------------------------------------------------------------------------- + name inet0 Use inet0 to later refer to this port + mac hardware value can be: hardware, random or a literal MAC address + rx desc 256 number of descriptors to allocate for reception + tx desc 256 number of descriptors to allocate for transmission + promiscuous yes enable promiscuous mode + strip crc yes enable CRC stripping + rss yes enable RSS + lsc no While lsc is disabled for drivers known to not provide support, + this option explicitely overrides these settings. + rx_ring dpdk_ring_name use DPDK ring as an interface (receive side) + tx_ring dpdk_ring_name use DPDK ring as an interface (transmit side) + +* [VARIABLES]: Variables can be defined in the configuration file using the $varname=value syntax. + Variables defined on the command line (-w varname=value) take precedence and do not create + conflicts with variables defined in the configuration file. Variables are used in the + configuration file using the $varname syntax: each instance of $varname is replaced by its + associated value. This is typically useful if the same parameter must be used at several places. + For instance, you might want to have multiple load balancers, all transmitting to the same set + of worker cores. The list of worker cores could then be defined once in a variable: + +:: + + [variables] + $wk=1s0-5s0 + +Then, a load balancer definition would use the variable: + +:: + + [core 6s0] + name=LB + task=0 + mode=lbnetwork + tx cores=$wk task=0 + ... + +And the section defining the worker cores would be: + +:: + + [core $wk] + name=worker + task=0 + mode=qinqencapv4 + ... + +* [DEFAULTS]: The default value of some options can be overridden using the [defaults] section: + +:: + + PARAMETER EXAMPLE DESCRIPTION + ----------------------------------- + mempool size 16K number of mbufs per task, relevant when task receives from a port. + this is the n argument provided to rte_mempool_create() + qinq tag 0xa888 Set qinq tag for all tasks. The result of adding this option is the + same as adding qinq tag= to each task + memcache size 128 number of mbufs cached per core, default is 256 this is the cache_size + argument provided to rte_mempool_create() + +* [GLOBAL]: The following parameters are supported: + +:: + + PARAMETER EXAMPLE DESCRIPTION + ------------------------------------------------- + name BNG Name of the configuration, which will be shown in the title box at runtime. + start time 10 Time in seconds after which average statistics will be started. + Default value is 0. + duration time 30 Runtime duration in seconds, counted after start time. + This is typically useful to automate testing using + different parameters: PROX automatically exits when the + runtime duration has elapsed. Initialization and start time + are not included in this runtime duration. + For example, if start time is set to 10 and duration time is set to 30, + the total execution time (after initialization) will be 40 seconds. + Default value is 0, which means infinity and prevents PROX from automatically exiting. + shuffle yes When this parameter is set to yes, the order of mbufs + within mempools is randomized to simulate a system that has + been warmed up. Default value is no. + gre cfg /path/to/file.csv Path to CSV file that provides QinQ-to-GRE mapping. + Default value is gre_table.csv in same directory as + configuration file.

If there are tasks with mode=lat, F4 displays latency measurements made during the last second by each of those tasks. -F5 displays DPDK ring information. F6 is for L4 generation. If no command has been entered, numbers 1 to 6 can also be used to change the view on the system. -This is provided to allow changing screens in environments that do not pass function keys to PROX. - -Page Up and Page Down can be used to view per core statistics that would otherwise not fit on the screen. Escape quits PROX. -The history of previously entered commands can be navigated using the Up and Down arrows. Statistics can be reset with F12. - -COMMAND LINE OPTIONS --------------------- -Run PROX with the "--help" argument to display the usage text and the list of supported options as shown below. -PROX supports many compilation flags to enable or disable features. For these flags, refer to the Makefile. -Refer to the README file for more information on how to run PROX for specific use cases. - -:: - - Usage: ./build/prox [-f CONFIG_FILE] [-l LOG_FILE] [-p] [-o DISPLAY] [-v] [-a|-e] [-m|-s|-i] [-n] [-w DEF] [-q] [-k] [-d] [-z] [-r VAL] [-u] [-t] - -f CONFIG_FILE : configuration file to load, ./prox.cfg by default - -l LOG_FILE : log file name, ./prox.log by default - -p : include PID in log file name if default log file is used - -o DISPLAY: Set display to use, can be 'curses' (default), 'cli' or 'none' - -v verbosity : initial logging verbosity - -a : autostart all cores (by default) - -e : don't autostart - -n : Create NULL devices instead of using PCI devices, useful together with -i - -m : list supported task modes and exit - -s : check configuration file syntax and exit - -i : check initialization sequence and exit - -u : Listen on UDS /tmp/prox.sock - -t : Listen on TCP port 8474 - -q : Pass argument to Lua interpreter, useful to define variables - -w : define variable using syntax varname=value - takes precedence over variables defined in CONFIG_FILE - -k : Log statistics to file "stats_dump" in current directory - -d : Run as daemon, the parent process will block until PROX is not initialized - -z : Ignore CPU topology, implies -i - -r : Change initial screen refresh rate. If set to a lower than 0.001 seconds, - screen refreshing will be disabled - -CONFIGURATION FILE FORMAT -------------------------- -The configuration file is divided into multiple sections, each of which is used to define some parameters and options. -Sections are created using the [section name] syntax. The list of sections, where # represents an integer, is as follows: - -:: - [eal options] - [port #] - [variables] - [defaults] - [global] - [core #] - -In each section, entries are created using the key=value syntax. -Comments are created using the ; symbol: all characters from the ; -symbol to the end of line are ignored. A # symbol at the beginning of the section name comments -the whole section out: all entries in the section are treated as comments and are ignored. For example: - -:: - [#core 1] - ; this is a comment - parameter name=parameter value ; this entry is ignored because the section is commented out - -[EAL OPTIONS] -The following parameters are supported: - -:: - -m ; Specifies the amount of memory used. If not provided, all hugepages will be used. - -n ; Specifies the number of memory channels. Use -n4 for latest Intel Xeon based platforms - -r ; Specifies the number of memory ranks. - eal ; Specifies DPDK EAL extra options. Those options will be passed blindly to DPDK. - -[PORT #] -DPDK ports are usually referenced by their port_id, i.e. an integer starting from 0. -Using port_id in the configuration file is tedious, since the same port_id can appear at -different places (rx port, tx port, routing tables), -and those ports might change (e.g. if cables are swapped). -In order to make the configuration file easier to read and modify, -DPDK ports are given a name with the name= option. -The name serves as the reference, and in addition, it will show up in the display at runtime. - -:: - PARAMETER EXAMPLE DESCRIPTION - ---------------------------------------------------------------------------- - name inet0 Use inet0 to later refer to this port - mac hardware value can be: hardware, random or a literal MAC address - rx desc 256 number of descriptors to allocate for reception - tx desc 256 number of descriptors to allocate for transmission - promiscuous yes enable promiscuous mode - strip crc yes enable CRC stripping - rss yes enable RSS - lsc no While lsc is disabled for drivers known to not provide support, - this option explicitely overrides these settings. - rx_ring dpdk_ring_name use DPDK ring as an interface (receive side) - tx_ring dpdk_ring_name use DPDK ring as an interface (transmit side) - -[VARIABLES] -Variables can be defined in the configuration file using the $varname=value syntax. -Variables defined on the command line (-w varname=value) take precedence and do not -create conflicts with variables defined in the configuration file. Variables are -used in the configuration file using the $varname syntax: each instance of $varname -is replaced by its associated value. This is typically useful if the same parameter -must be used at several places. For instance, you might want to have multiple load -balancers, all transmitting to the same set of worker cores. -The list of worker cores could then be defined once in a variable: - -:: - [variables] - $wk=1s0-5s0 - -Then, a load balancer definition would use the variable: - -:: - [core 6s0] - name=LB - task=0 - mode=lbnetwork - tx cores=$wk task=0 - ... - -And the section defining the worker cores would be: - -:: - [core $wk] - name=worker - task=0 - mode=qinqencapv4 - ... - -[DEFAULTS] -The default value of some options can be overridden using the [defaults] section: - -:: - PARAMETER EXAMPLE DESCRIPTION - ----------------------------------- - mempool size 16K number of mbufs per task, relevant when task receives from a port. - this is the n argument provided to rte_mempool_create() - qinq tag 0xa888 Set qinq tag for all tasks. The result of adding this option is the - same as adding qinq tag= to each task - memcache size 128 number of mbufs cached per core, default is 256 this is the cache_size - argument provided to rte_mempool_create() - -[GLOBAL] -The following parameters are supported: - -:: - PARAMETER EXAMPLE DESCRIPTION - ------------------------------------------------- - name BNG Name of the configuration, which will be shown in the title box at runtime. - start time 10 Time in seconds after which average statistics will be started. - Default value is 0. - duration time 30 Runtime duration in seconds, counted after start time. - This is typically useful to automate testing using - different parameters: PROX automatically exits when the - runtime duration has elapsed. Initialization and start time - are not included in this runtime duration. - For example, if start time is set to 10 and duration time is set to 30, - the total execution time (after initialization) will be 40 seconds. - Default value is 0, which means infinity and prevents PROX from automatically exiting. - shuffle yes When this parameter is set to yes, the order of mbufs - within mempools is randomized to simulate a system that has - been warmed up. Default value is no. - gre cfg /path/to/file.csv Path to CSV file that provides QinQ-to-GRE mapping. - Default value is gre_table.csv in same directory as - configuration file. Fields are GRE key and QinQ value (computed as SVLAN * 4096 + CVLAN). - pre cmd ls Arbitrary system commands to run while reading cfg. This option can occur multiple times. - user cfg /path/to/file.csv Path to CSV file that provides QinQ-to-User mapping. - Default value is user_table.csv in same directory as configuration file. - Fields are SVLAN, CVLAN and User-Id. - next hop cfg /path/to/file.csv Path to CSV file that provides Next-Hop details. - Default value is next_hop.csv in same directory as configuration file. - Fields are Next-Hop index (as returned by LPM lookup), - Out-Port index, Next-Hop IP (unused), Next-Hop MAC and MPLS label. - ipv4 cfg /path/to/file.csv Path to CSV file that provides IPv4 LPM routing table. - Default value is ipv4.csv in same directory as configuration file. - Fields are IPv4 subnet (in CIDR notation) and Next-Hop index. - dscp cfg /path/to/file.csv Path to CSV file that provides mapping for QoS classification, - from DSCP to Traffic Class and Queue. - Default value is dscp.csv in same directory as configuration file. - Fields are DSCP (0-63), Traffic Class (0-3) and Queue (0-3). - ipv6 tunnel cfg /path/to/file.csv Path to CSV file that provides lwAFTR binding table. - Default value is ipv6_tun_bind.csv in same directory as configuration file. - Fields are lwB4 IPv6 address, next hop MAC address towards lwB4, - IPv4 Public address and IPv4 Public Port Set. - acl cfg /path/to/file.csv Path to CSV file that provides ACL rules. - Default value is rules.csv in same directory as configuration file. - Fields are SVLAN value & mask, CVLAN value & mask, IP protocol value & mask, - source IPv4 subnet (in CIDR notation), destination IPv4 subnet (in CIDR notation), - source port range, destination port range, and action (drop, allow, rate limit). - unique mempool yes - per socket - -[CORE #] -Cores can be configured by means of a set of [core #] sections, where # represents either: - -an absolute core number: e.g. on a 10-core, dual socket system with hyper-threading, cores are numbered from 0 to 39; -a core number, the letter 's', and a socket number: this allows selecting per-socket cores, independently from their interleaved numbering; -a core number and the letter 'h': this allows selecting the hyper-thread sibling of the specified core; -a dash-separated range of core numbers; -a comma-separated list of core numbers; -any combination of the above; -or a variable whose value complies with the above syntax. -The socket and hyper-thread syntax makes it easier to use the same configuration file on several platforms, -even if their core numbering differs (e.g. interleaving rule or number of cores per socket). - -Each core can be assigned with a set of tasks, each running one of the implemented packet processing modes. - -The following parameters are supported: -.. image:: images/prox_core.png - :width: 1024px - :alt: SampleVNF supported topology - -INSTALLATION ------------- - -PREREQUISITES -^^^^^^^^^^^^^ -DPDK must be installed prior to running make in the PROX directory. -The README file shipped with PROX describes what versions of DPDK are supported, -and if any patches are needed for the chosen DPDK version. - -The following packages need to be installed.
