NAME

       teamd.conf — libteam daemon configuration file

DESCRIPTION

       teamd uses JSON format configuration.

OPTIONS

       device (string)
              Desired name of new team device.

       debug_level (int)
              Level  of debug messages. The higher it is the more debug messages will be printed.
              It is the same as adding "-g" command line options.

              Default: 0 (disabled)

       hwaddr (string)
              Desired hardware address of new team device. Usual MAC address format is accepted.

       runner.name (string)
              Name of team device. The following runners are available:

              broadcast — Simple runner which directs the team device to transmit packets via all
              ports.

              roundrobin  — Simple runner which directs the team device to transmits packets in a
              round-robin fashion.

              random — Simple runner which directs the team device  to  transmits  packets  on  a
              randomly selected port.

              activebackup — Watches for link changes and selects active port to be used for data
              transfers.

              loadbalance — To do passive load balancing, runner only sets up BPF  hash  function
              which  will determine port for packet transmit. To do active load balancing, runner
              moves hashes among available ports trying to reach perfect balance.

              lacp  —  Implements  802.3ad  LACP  protocol.  Can  use  same  Tx  port   selection
              possibilities as loadbalance runner.

              Default: roundrobin

       notify_peers.count (int)
              Number  of  bursts of unsolicited NAs and gratuitous ARP packets sent after port is
              enabled or disabled.

              Default: 0 (disabled)

              Default for activebackup runner: 1

       notify_peers.interval (int)
              Value is positive number in milliseconds. Specifies an interval between  bursts  of
              notify-peer packets.

              Default: 0

       mcast_rejoin.count (int)
              Number  of  bursts of multicast group rejoin requests sent after port is enabled or
              disabled.

              Default: 0 (disabled)

              Default for activebackup runner: 1

       mcast_rejoin.interval (int)
              Value is positive number in milliseconds. Specifies an interval between  bursts  of
              multicast group rejoin requests.

              Default: 0

       link_watch.name | ports.PORTIFNAME.link_watch.name (string)
              Name of link watcher to be used. The following link watchers are available:

              ethtool — Uses Libteam lib to get port ethtool state changes.

              arp_ping  —  ARP requests are sent through a port. If an ARP reply is received, the
              link is considered to be up.

              nsna_ping — Similar to the previous, except that it uses IPv6 Neighbor Solicitation
              /  Neighbor Advertisement mechanism. This is an alternative to arp_ping and becomes
              handy in pure-IPv6 environments.

       ports (object)
              List of ports, network devices, to be used in a team device.

              See examples for more information.

       ports.PORTIFNAME.queue_id (int)

              Default: None

ACTIVE-BACKUP RUNNER SPECIFIC OPTIONS

       runner.hwaddr_policy (string)
              This defines the policy of how hardware addresses of team device and  port  devices
              should be set during the team lifetime. The following are available:

              same_all  —  All ports will always have the same hardware address as the associated
              team device.

              by_active — Team device adopts the hardware address of the currently  active  port.
              This is useful when the port device is not able to change its hardware address.

              only_active  — Only the active port adopts the hardware address of the team device.
              The others have their own.

              Default: same_all

       ports.PORTIFNAME.prio (int)
              Port priority. The higher number means higher priority.

              Default: 0

       ports.PORTIFNAME.sticky (bool)
              Flag which indicates if the port is sticky. If set, it means the port does not  get
              unselected  if  another  port  with  higher  priority  or better parameters becomes
              available.

              Default: false

LOAD BALANCE RUNNER SPECIFIC OPTIONS

       runner.tx_hash (array)

              if it is still usable.

              bandwidth — Select aggregator with highest total bandwidth.

              count — Select aggregator with highest number of ports.

              port_config  —  Aggregator with highest priority according to per-port options prio
              and sticky will be selected. This means that the  aggregator  containing  the  port
              with  the highest priority will be selected unless at least one of the ports in the

EXAMPLES

       {
         "device": "team0",
         "runner": {"name": "roundrobin"},
         "ports": {"eth1": {}, "eth2": {}}
       }

       Very basic configuration.

       {
         "device": "team0",
         "runner": {"name": "activebackup"},
         "link_watch": {"name": "ethtool"},
         "ports": {
           "eth1": {
             "prio": -10,
             "sticky": true
           },
           "eth2": {
             "prio": 100
           }
         }
       }

       This configuration uses active-backup runner with ethtool  link  watcher.  Port  eth2  has
       higher  priority, but the sticky flag ensures that if eth1 becomes active, it stays active
       while the link remains up.

       {
         "device": "team0",
         "runner": {"name": "activebackup"},
         "link_watch": {
           "name": "ethtool",
           "delay_up": 2500,
           "delay_down": 1000
         },
         "ports": {
           "eth1": {
             "prio": -10,
             "sticky": true
           },
           "eth2": {
             "prio": 100
           }
         }
       }

       Similar to the previous one. Only difference is that link changes are  not  propagated  to
       the runner immediately, but delays are applied.

       {
         "device": "team0",
         "runner": {"name": "activebackup"},
         "link_watch":     {
           "name": "arp_ping",
           "interval": 100,
           "missed_max": 30,
           "target_host": "192.168.23.1"
         },
         "ports": {
           "eth1": {
             "prio": -10,
             "sticky": true
           },
           "eth2": {
             "prio": 100
           }
         }
       }

       This configuration uses ARP ping link watch.

       {
       "device": "team0",
       "runner": {"name": "activebackup"},
       "link_watch": [
         {
           "name": "arp_ping",
           "interval": 100,
           "missed_max": 30,
           "target_host": "192.168.23.1"
         },
         {
           "name": "arp_ping",
           "interval": 50,
           "missed_max": 20,
           "target_host": "192.168.24.1"
         }
       ],
       "ports": {
         "eth1": {
           "prio": -10,
           "sticky": true
         },
         "eth2": {
           "prio": 100
           }
         }
       }

       Similar to the previous one, only this time two link watchers are used at the same time.

       {
         "device": "team0",
         "runner": {
           "name": "loadbalance",
           "tx_hash": ["eth", "ipv4", "ipv6"]
         },
         "ports": {"eth1": {}, "eth2": {}}
       }

       Configuration for hash-based passive Tx load balancing.

       {
         "device": "team0",
         "runner": {
           "name": "loadbalance",
           "tx_hash": ["eth", "ipv4", "ipv6"],
           "tx_balancer": {
             "name": "basic"
           }
         },
         "ports": {"eth1": {}, "eth2": {}}
       }

       Configuration for active Tx load balancing using basic load balancer.

       {
         "device": "team0",
         "runner": {
           "name": "lacp",
           "active": true,
           "fast_rate": true,
           "tx_hash": ["eth", "ipv4", "ipv6"]
         },
         "link_watch": {"name": "ethtool"},
         "ports": {"eth1": {}, "eth2": {}}
       }

       Configuration for connection to LACP capable counterpart.
