NAME

ifcfg-team - interface team configuration

SYNOPSIS

/etc/sysconfig/network/ifcfg-*

Team Interfaces

To setup a team interface you need a configuration file ifcfg-team<X> with the usual network settings. But you must add additional variables

TEAM_DEBUG_LEVEL
Level of debug messages. The higher it is the more debug messages will be printed.

Default: 0 (disabled)

TEAM_NOTIFY_PEERS_COUNT
Number of bursts of unsolicited NAs and gratuitous ARP packets sent after port is enabled or disabled. If not set, use teamd default.
TEAM_NOTIFY_PEERS_INTERVAL
Value is positive number in milliseconds. Specifies an interval between bursts of notify-peer packets. If not set, use teamd default.
TEAM_MCAST_REJOIN_COUNT
Number of bursts of multicast group rejoin requests sent after port is enabled or disabled. If not set, use teamd default.
TEAM_MCAST_REJOIN_INTERVAL
Value is positive number in milliseconds. Specifies an interval between bursts of multicast group rejoin requests. If not set, use teamd default.
TEAM_RUNNER
must be set to one of the following types to identify this interface as a team interface:

broadcast – Team device transmits packets via all its ports.

roundrobin – Team device transmits packets via all its ports with round-robin method.

activebackup – Team device monitors ports’ link changes and uses port with active link to transmit packets.

loadbalance – Team device transmits packets via all its ports performing load balancing (passive or active) with a use of hash functions. For passive load balancing only BPF hash function is used. For active load balancing runner finds best balance by moving hashes between available ports.

lacp – Implements 802.3ad LACP protocol.

ACTIVE-BACKUP RUNNER SPECIFIC OPTIONS

TEAM_AB_HWADDR_POLICY
Determines the hardware addresses assignment for team device instance and its ports. This assignment is performed during team device instance creation and also for each new port added to the existing instance. The followingi modes 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

LOAD BALANCE RUNNER SPECIFIC OPTIONS

TEAM_LB_TX_HASH
A list of string elements separated by a comma “,” which should be used for packet Tx hash computation. The following elements are available:

eth – Uses source and destination MAC addresses.

vlan – Uses VLAN id.

ipv4 – Uses source and destination IPv4 addresses.

ipv6 – Uses source and destination IPv6 addresses.

ip – Uses source and destination IPv4 and IPv6 addresses.

l3 – Uses source and destination IPv4 and IPv6 addresses.

tcp – Uses source and destination TCP ports.

udp – Uses source and destination UDP ports.

sctp – Uses source and destination SCTP ports.

l4 – Uses source and destination TCP and UDP and SCTP ports.

TEAM_LB_TX_BALANCER_NAME
Name of active Tx balancer. Currently only supported value is basic.
TEAM_LB_TX_BALANCER_INTERVAL
Rebalancing interval. To be specified in tenths of a second.

Default: 50

LACP RUNNER SPECIFIC OPTIONS

TEAM_LACP_ACTIVE
Active mode enables sending LACPDU frames through configured link periodically.

Default: true

TEAM_LACP_SYS_PRIO
System priority, value can be 0 - 65535.

Default: 255

TEAM_LACP_FAST_RATE
Fast rate asks link partner to transmit LACPDU frames once per second. Otherwise they are sent every 30 seconds.

Default: true

TEAM_LACP_MIN_PORTS
Minimum number of active ports required to assert carrier in master device. Value can be 1 - 255.

Default: 0

TEAM_LACP_SELECT_POLICY
The policy of how the aggregators will be selected. The following are available:

lacp_prio – Aggregator with highest priority according to LACP standard will be selected. Aggregator priority is affected by per-port option “lacp_prio”.

lacp_prio_stable – Same as previous one, except do not replace selected aggregator if it is still usable.

bandwidth – Select aggregator with highest total bandwidth.

count – Select aggregator with highest number of ports.

port_options – 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 currently selected aggregator is sticky.

Default: lacp_prio

TEAM_LACP_TX_HASH
Same as for loadbalancer runner. Please refer to the section above.
TEAM_LACP_TX_BALANCER
Same as for loadbalancer runner. Please refer to the section above.
TEAM_LACP_TX_BALANCER_INTERVAL
Same as for loadbalancer runner. Please refer to the section above.

LINK WATCH OPTIONS

TEAM_LINK_WATCH_POLICY
Declare name of link-watchers evaluation policy. The following options are available:

any – Link is up if any of the link-watchers reports the link up.

all – Link is up if all of the link-watchers reports the link up.

Default: any

TEAM_LW_NAME[SUFFIX]
Declares the type name of link watch (with the specified unique watch suffix). To declare several link watches, append the same suffix to all variables of one watch. The following types 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.

ETHTOOL LINK WATCH SPECIFIC OPTIONS

TEAM_LW_ETHTOOL_DELAY_UP[SUFFIX]
Delay between the link coming up and the runner being notified about it (in milliseconds).

Default: 0

TEAM_LW_ETHTOOL_DELAY_DOWN[SUFFIX]
Delay between the link going down and the runner being notified about it (in milliseconds).

Default: 0

ARP PING LINK WATCH SPECIFIC OPTIONS

TEAM_LW_ARP_PING_SOURCE_HOST[SUFFIX]
Hostname or IP address used in ARP request as source address.

Default: 0.0.0.0

TEAM_LW_ARP_PING_TARGET_HOST[SUFFIX]

Default: false

TEAM_LW_ARP_PING_SEND_ALWAYS[SUFFIX]

Default: false

TEAM_LW_ARP_PING_MISSED_MAX[SUFFIX]
Maximum number of missed ARP replies. If this number is exceeded, link is reported as down.

TEAM_LW_ARP_PING_VLANID[SUFFIX]
By default, ARP requests are sent without VLAN tags. This option causes outgoing ARP requests to be sent with the specified VLAN ID number.

NS/NA PING LINK WATCH SPECIFIC OPTIONS

TEAM_LW_NSNA_PING_TARGET_HOST[SUFFIX]
Hostname or IPv6 address used in NS packet as target address.
TEAM_LW_NSNA_PING_INTERVAL[SUFFIX]

Default: false

TEAM_PORT_PRIO[SUFFIX]
Port priority in activebackup runner. The higher number means higher priority.

Default: 0

TEAM_PORT_LACP_PRIO[SUFFIX]
Port priority according to LACP standard. The lower number means higher priority.

Port key according to LACP standard. It is only possible to aggregate ports with the same key.

Default: 0
