路由器和交換機(jī)

1、路由器和交換機(jī)之間的端口聚合實(shí)驗(yàn)本文章翻譯自Cisco官網(wǎng)文檔： HYPERLINK http:/www.cisco.eom/c/en/us/support/docs/switches/catalyst-2950-series-switches/24042-158 http:/www.cisco.eom/c/en/us/support/docs/switches/catalyst-2950-series-switches/24042-158. html這篇文檔提供了一種在思科二層交換機(jī)和思科路由器關(guān)于Fast EtherChannel (FEC) and IEEE 802.1Q trunkin

SP2, RSP4)Y&sYes思科2600,3600和3700系列路由器在端口聚合特性上要單獨(dú)提出來(lái)，當(dāng)你安裝了交換模 塊(NM-16ESW或者NM-36ESW)時(shí)，這些模塊支持最大6個(gè)端口聚合，而一般的端口 聚合最大支持8個(gè)端口聚合。RSP = Route Switch Processor以下實(shí)驗(yàn)使用：Catalyst 2950 交換機(jī)，運(yùn)行 Cisco IOS Software Release 12.1(9)EA1d.Cisco 7200 路由器，運(yùn)行 Cisco IOS Software Release 12.2(3).端口聚合原理：端口聚合將Fast Ethernet(F

5、E)或Gigabit Ethernet(GE)端 口劃分成一個(gè)邏輯組，8個(gè)端口聚合將 能達(dá)到800Mbps或8Gbps的速率。端口聚合能在交換機(jī)、路由器、服務(wù)器上提供鏈路冗余、 高速可靠鏈路特性。同時(shí)，端口聚合也支持interVLAN通信，在校園網(wǎng)中，你可以在傳遞多 個(gè)VLAN通信量的端口聚合鏈路上進(jìn)行配置。實(shí)驗(yàn)拓?fù)鋱D如下:int FaitEthemet 3/0VLAN 1054FastElhernei MFastEUiern et 0/2Fas.iEthemet 0/15FastEthernet 0/5VLAN 20)Fast EtherChannelorkstaiion54配置如下：1.交
