Allows you to specify the bonding policy. The <value> can be one of:
balance-rr or 0 — Sets a round-robin policy for fault tolerance and load balancing. Transmissions are received and sent out sequentially on each bonded slave interface beginning with the first one available.
active-backup or 1 — Sets an active-backup policy for fault tolerance. Transmissions are received and sent out via the first available bonded slave interface. Another bonded slave interface is only used if the active bonded slave interface fails.
balance-xor or 2 — Sets an XOR (exclusive-or) policy for fault tolerance and load balancing. Using this method, the interface matches up the incoming request's MAC address with the MAC address for one of the slave NICs. Once this link is established, transmissions are sent out sequentially beginning with the first available interface.
broadcast or 3 — Sets a broadcast policy for fault tolerance. All transmissions are sent on all slave interfaces.
802.3ad or 4 — Sets an IEEE 802.3ad dynamic link aggregation policy. Creates aggregation groups that share the same speed and duplex settings. Transmits and receives on all slaves in the active aggregator. Requires a switch that is 802.3ad compliant.
balance-tlb or 5 — Sets a Transmit Load Balancing (TLB) policy for fault tolerance and load balancing. The outgoing traffic is distributed according to the current load on each slave interface. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed slave. This mode is only suitable for local addresses known to the kernel bonding module and therefore cannot be used behind a bridge with virtual machines.
balance-alb or 6 — Sets an Adaptive Load Balancing (ALB) policy for fault tolerance and load balancing. Includes transmit and receive load balancing for IPv4 traffic. Receive load balancing is achieved through ARP negotiation. This mode is only suitable for local addresses known to the kernel bonding module and therefore cannot be used behind a bridge with virtual machines.

lacp_rate=<value>
slow or 0 — Default setting. This specifies that partners should transmit LACPDUs every 30 seconds.
fast or 1 — Specifies that partners should transmit LACPDUs every 1 second.

#1.测试 配置单网卡允许多个vlan通过 
Network 设备
interface Eth-Trunk100
description BOND-VLAN
port link-type trunk
port trunk allow-pass vlan 999

Server 设备 em2为例 例如vlan 999 需要创建 ifcfg-em2.vlan(编号) 本例 ifcfg-em2.999；如果还需创建其他vlan ifcfg-em2.vlan(编号)
ifcfg-em2
DEVICE=em2
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none

vi ifcfg-em2.999
DEVICE=em2.999
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.99.253
NETMASK=255.255.255.192
USERCTL=no
VLAN=yes #增加vlan

#2.测试配置 bond mode 4 (8023.ad)允许多个vlan通过 vlan999 和vlan2204；用bond0 em1-em2 物理网卡
Network 设备
interface Eth-Trunk100
description BOND-VLAN
