freebsd 双网卡（trunking）主备的问题--已解决

rhinux

简单配置如下

#!/bin/sh /usr/sbin/ngctl mkpeer fec dummy fec /usr/sbin/ngctl msg fec0: add_iface '"bge0"' /usr/sbin/ngctl msg fec0: add_iface '"bge1"' /usr/sbin/ngctl msg fec0: set_mode_inet /sbin/ifconfig fec0 promisc /sbin/ifconfig bge0 promisc /sbin/ifconfig bge1 promisc /sbin/ifconfig fec0 192.168.139.28 netmask 0xfffffe00 /sbin/ifconfig fec0 media 1000baseTX mediaopt full-duplex /sbin/ifconfig fec0 up /sbin/route add default 192.168.139.1

结果如下

1. em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
   
2.         options=1db<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,POLLING,VLAN_HWCSUM,TSO4>

目前两块物理网卡（bge0，beg1）是处于负载均衡状态，我要如何指定主备状态呢

希望懂的兄弟帮忙看看，另外ngctl的手册过于简单，没看出啥来
谢谢

忽略了一个问题，大概已经有思路了，关键是在网卡的模式上PROMISC还是MASTER或者。。。。

用新版freebsd的 lagg 已经解决

早就用LAGG了，谁还用if_nec呀。不过LAGG和某些交换机有兼容性问题。
