Summit Switch & Cisco Etherchannel介绍
Summit Switch & Cisco Etherchannel\r\n\r\n\r\n有没有朋友做过Summit Switch & Cisco Etherchannel的连接.\r\n\r\n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.\r\n\r\n要连接的是SUMMIT5i,从5i的Feature上看是支持IEEE 802.1ad compatible link aggre\r\ngation 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.\r\n\r\n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.\r\n\r\n[7600]\r\n||||\r\n|||| -----etherchannel(fastether x 4)\r\n||||\r\n[summit5i]\r\n|\r\n| -----fastether\r\n|\r\n[7200]\r\n\r\n*****************************************************************************\r\n先说[summit5i]的设定\r\n#\r\n#这4个port连着[7600]的1,2,3,4 port\r\nconfigure port 1 auto off speed 100 duplex full\r\nconfigure port 2 auto off speed 100 duplex full\r\nconfigure port 3 auto off speed 100 duplex full\r\nconfigure port 4 auto off speed 100 duplex full\r\n#\r\n#port8连着的是7200的FE1/0\r\nconfigure port 8 auto off speed 100 duplex full\r\n#\r\n#summit的sharing-grouping\r\nenable sharing 1 grouping 1,2,3,4 algorithm round-robin\r\nSummit5iTx:45 # sh port sh\r\nNext possible completions:\r\n<cr>\r\n\r\nSummit5iTx:45 # sh port sharing \r\nLoad Sharing Monitor\r\nConfig Current Ld Share Ld Share Link Link\r\nMaster Master Algorithm Group Status Ups\r\n==========================================================\r\n1 1 r 1 A 11 \r\nr 2 A 9 \r\nr 3 A 26 \r\nr 4 A 9 \r\nFlags: Link Status: A-Active, R-Ready, D-Disabled, NP-Not Present\r\nLd Sh Algo: p-port based, a-address based, r-round robin\r\n\r\n*****************************************************************\r\n[7200]的设定(没什么特别,只是为了测试而已)\r\ninter loop0\r\nip address 2.2.2.2 255.255.255.0\r\ninter fa0/1\r\nip address 192.168.1.3 255.255.255.0\r\nduplex full\r\nno shut\r\nrouter ospf 1\r\nnetwork 192.168.1.3 0.0.0.0 area 0\r\nnetwork 2.2.2.0 0.0.0.255 area 0\r\n\r\n***************************************************************\r\n[7600] 的设定\r\n有两种Etherchannel,一种是layer2的,一种是layer3的\r\n(1) layer2 Etherchannel\r\ninter loop0\r\nip address 1.1.1.1 255.255.255.0\r\ninterface range fa3/1 – 4\r\nswitchport\r\nswitchport mode access\r\nswitchport access vlan 10\r\nchannel-group 2 mode on \r\n\r\n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\r\n!\r\ninterface Port-channel 2\r\nno ip address\r\nno logging event link-status\r\nswitchport\r\nswitchport access vlan 10\r\nswitchport mode access\r\n!\r\nRouter#sh etherchannel summary \r\nFlags: D - down P - in port-channel\r\nI - stand-alone s - suspended\r\nH - Hot-standby (LACP only)\r\nR - Layer3 S - Layer2\r\nU - in use f - failed to allocate aggregator\r\n\r\nu - unsuitable for bundling\r\nNumber of channel-groups in use: 1\r\nNumber of aggregators: 1\r\n\r\nGroup Port-channel Protocol Ports\r\n------+-------------+-----------+-----------------------------------------------\r\n2 Po2(SU) - Fa3/1(P) Fa3/2(P) Fa3/3(P) Fa3/4(P) \r\n\r\nRouter#\r\n\r\n***************************************************************************\r\n(2) layer3 Etherchannel\r\n\r\ninterface Port-channel 5\r\nip address 192.168.1.1 255.255.255.0\r\n!\r\ninterface range fa3/1 – 4\r\nspeed 100\r\nduplex full\r\nno cdp enable\r\nchannel-group 5 mode on\r\nno shut\r\n!\r\nrouter ospf 1\r\nnetwork 192.168.1.1 0.0.0.0 area 0\r\nnetwork 1.1.1.1 0.0.0.0 area 0\r\ndefault-information originate always\r\n\r\n\r\nRouter#sh etherchannel summary \r\nFlags: D - down P - in port-channel\r\nI - stand-alone s - suspended\r\nH - Hot-standby (LACP only)\r\nR - Layer3 S - Layer2\r\nU - in use f - failed to allocate aggregator\r\n\r\nu - unsuitable for bundling\r\nNumber of channel-groups in use: 1\r\nNumber of aggregators: 1\r\n\r\nGroup Port-channel Protocol Ports\r\n------+-------------+-----------+-----------------------------------------------\r\n5 Po5(RU) - Fa3/1(P) Fa3/2(P) Fa3/3(P) Fa3/4(P) \r\n\r\n\r\n以上两种etherchannel在CISCO的sweep ping下,都不会丢包.\r\n\r\n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.\r\n\r\n简单扼要就这些了. |
