EtherChannel最初是由cisco提出,通过聚合多条物理链路为单条逻辑链路,从而实现高可用及提高吞吐量等目的.AgP(Port Aggregation Protocol,Cisco专有协议).LACP(IEEE 802.3ad)是应用最广泛的两种实现.Linux中的实现称为Bonding,HA的实现需要系统层面Bonding和物理层面switch紧密配合. 参考资料:http://www.mjmwired.net/kernel/Documentation/networking/bondi…

记录一下四次握手的log. PMK: PMK(Pairwise Master Key,成对主密钥 STA和AP得到PMK后,将进行密匙派生以得到PTK.最后,PTK被设置到硬件中, 用于数据的加解密. ·由于AP和STA都需要使用PTK,所以二者需要利用EAPOL Key帧进行信息交换. 这就是4-Way Handshake的作用. 由于STA每次关联都需要重新派生这些 Key,所以它们称为PTK(Pairwise Transient Key,成对临时Key), 09-04 16:01:00.3…

先查看网卡mac地址,由于我的服务器做了mac地址绑定,所以会有相同的hwaddr地址,请忽略. [root@node-0a0a05d3- net]# ifconfig eth0 | grep HWaddr eth0 Link encap:Ethernet HWaddr 18:66:DA:6F:AF:9B [root@node-0a0a05d3-0 net]# ifconfig eth1 | grep HWaddr eth1 Link encap:Ethernet HWaddr 18:66:DA…

Linux下可以设置网卡模式 模式0:负载均衡 模式1:主备模式,不提高网络带宽 模式3:多网卡同时发送相同的数据 准备实验环境: Redhat 6.4 企业版64位,最小化安装. 给虚拟机添加网卡 此时我虚拟机有2块网卡,但是真正启用工作的只有一块,使用ifconfig也只能看到一块网卡.ifconfig -a可以看到我们加入的另一块网卡,此时这块网卡还没有启用. [root@51cto network-scripts]# ifconfig -a eth0 Link encap:Etherne…
