Summit Switch & Cisco Etherchannel

有没有朋友做过Summit Switch & Cisco Etherchannel的连接.

http://www.it55.com/

查了CCO, cisco etherchannel要和第三方的SWITCH建立Etherchannel的连接,要用LACP.是基于IEEE802.3AD的标准. sflj www.it55.com kg^&fgd

要连接的是SUMMIT5i,从5i的Feature上看是支持IEEE 802.1ad compatible link aggre gation 的(CISCO叫Etherchanne,SUMMIT叫link aggregation,也叫sharing-group),但我们的firmware是6.xx的,对802.1AD是draft,有查了新的firmware是7.0.0,是支持IEEE 802.1ad 的.

实验成功了.虽然summit5i和cisco etherchannel之间有很多不同,但经过一些实验,得到好的结果. IT资讯之家 www.it55.com

[7600] 的设定

有两种Etherchannel,一种是layer2的,一种是layer3的

(1) layer2 Etherchannel

inter loop0

ip address 1.1.1.1 255.255.255.0

interface range fa3/1 – 4

switchport

switchport mode access

switchport access vlan 10

channel-group 2 mode on <<<<<<< 注意这里用的是[on],后面再讲其它的Mode

speed 100

duplex full

no shut

no cdp enable

!

no spanning-tree vlan 10 <<<<<主要是关掉不必要的port nego,不了解的朋友不要用

!

inter vlan 10

ip address 192.168.1.1 255.255.255.0

实际上,在敲完以上的config,你会发现interface Port-channel1已经被路由器自己生成了

!

interface Port-channel 2

no ip address

no logging event link-status

switchport

switchport access vlan 10

switchport mode access

以上两种etherchannel在CISCO的sweep ping下,都不会丢包.

但是如果你把channel-group 5 mode XX设成了其它象［active,passive］, 都会丢包,更不用说设成了［auto ,desirable］了,summit根本不支持. it55.com

简单扼要就这些了。 www.it55.com在线教程
