更改接口绑定模式的语法

我希望能够使用 ip link 命令更改接口的绑定模式，但我无法找出正确的语法。该命令的帮助文本是：

$ ip link help bond
Usage: ... bond [ mode BONDMODE ] [ active_slave SLAVE_DEV ]
                [ clear_active_slave ] [ miimon MIIMON ]
                [ updelay UPDELAY ] [ downdelay DOWNDELAY ]
                [ use_carrier USE_CARRIER ]
                [ arp_interval ARP_INTERVAL ]
                [ arp_validate ARP_VALIDATE ]
                [ arp_all_targets ARP_ALL_TARGETS ]
                [ arp_ip_target [ ARP_IP_TARGET, ... ] ]
                [ primary SLAVE_DEV ]
                [ primary_reselect PRIMARY_RESELECT ]
                [ fail_over_mac FAIL_OVER_MAC ]
                [ xmit_hash_policy XMIT_HASH_POLICY ]
                [ resend_igmp RESEND_IGMP ]
                [ num_grat_arp|num_unsol_na NUM_GRAT_ARP|NUM_UNSOL_NA ]
                [ all_slaves_active ALL_SLAVES_ACTIVE ]
                [ min_links MIN_LINKS ]
                [ lp_interval LP_INTERVAL ]
                [ packets_per_slave PACKETS_PER_SLAVE ]
                 [ tlb_dynamic_lb TLB_DYNAMIC_LB ]
                [ lacp_rate LACP_RATE ]
                [ ad_select AD_SELECT ]
                [ ad_user_port_key PORTKEY ]
                [ ad_actor_sys_prio SYSPRIO ]
                [ ad_actor_system LLADDR ]

BONDMODE := balance-rr|active-backup|balance-xor|broadcast|802.3ad|balance-tlb|balance-alb
ARP_VALIDATE := none|active|backup|all
ARP_ALL_TARGETS := any|all
PRIMARY_RESELECT := always|better|failure
FAIL_OVER_MAC := none|active|follow
XMIT_HASH_POLICY := layer2|layer2+3|layer3+4|encap2+3|encap3+4
LACP_RATE := slow|fast
AD_SELECT := stable|bandwidth|count

我尝试了该命令的许多变体，如下所示的示例。我知道我可以使用各种发行版的接口文件来设置模式，但我只是想能够使用 ip link 命令，它对我在无需重新启动的情况下进行实时故障排除非常有用。

$ ip link set dev bt  mode 0
Error: argument "0" is wrong: Invalid link mode

$ ip link set dev bt  mode active-backup
Error: argument "active-backup" is wrong: Invalid link mode

谢谢

确保指定接口类型：

# ip link set dev bt type bond mode active-backup
