S5700的Eth-Trunk端口匯聚 鏈路匯聚和端口匯聚,，就是端口聚合,，交換機的堆疊是堆疊和端口聚合無關。 端口聚合概念：（包括二層端口聚合和三層端口聚合） 1.端口聚合IEEE標準是將最多16條鏈路聚合成一個邏輯的鏈路。其中只有8條可以使用,， 其余8條作為備份,。 2.做聚合的端口配置，物理介質性質（雙工模式,，接口帶寬等等）必須一樣 3.端口聚合可以提高帶寬,，但是不是物理上的提高，而是基于負載均衡的提高 4.做端口聚合的端口只能以2的倍數(shù)個鏈路做聚合,，即只能2,、4、6,、8條鏈路做聚合,， 不能是奇數(shù)鏈路做聚合 Eth-Trunk簡單端口匯聚：（本地負載均衡） SW1： [SW1]interface Eth-Trunk 1 #建立匯聚端口1 [SW1-Eth-Trunk1]port link-type access #更改端口為訪問端口，如果下面是兩臺交換機,，則需要更改為port link-type trunk模式,。 [SW1-Eth-Trunk1]mode manual load-balance #添加手動本地負載模式 [SW1-Eth-Trunk1]quit [SW1]interface GigabitEthernet 0/0/1 [SW1-GigabitEthernet0/0/1]eth-trunk1 #將端口0/0/1加入eth-trunk1 [SW1]interface GigabitEthernet 0/0/2 [SW1-GigabitEthernet0/0/2]eth-trunk1 #將端口0/0/2加入eth-trunk1 [SW1]interface vlan 1 [SW1-Vlanif1]ip address 192.168.1.254255.255.255.0 [SW1-Vlanif1]quit

注意：在本地配置Eth-Trunk的時候,，在對端也要進行Eth-Trunk的配置，且加上路由就可以實現(xiàn)不同網(wǎng)段間的互通,。 |
