微云云桌面網絡配置
?服務器所有網口安裝時已經設置成BST(bonding、switching、trunking)模式
?交換機需啟用802.1d生成樹協議
?交換與服務器連接的端口須設置成802.1Q trunk 端口
?交換機與服務器連接的端口還需設置成802.3ad lacp協議的聚合端口 ??建議配置兩臺的交換機冗余熱備,特別是分布式存儲的服務器要求網絡無單點故障才能確保可靠性
(服務器兩個以上網口同時接入不支持802.1d生成樹協議或生成樹協議未啟用的交換機將產生網絡回路,導致網絡風暴而使網絡不可用,大多交換機默認已經啟用802.1d生成樹協議)
?連接服務器端口須是千兆或萬兆口
?交換機要求支持并啟用802.1d生成樹協議
?交換機端口要求支持802.1q trunk 協議
?交換機端口要求支持802.3ad LACP 端口聚合協議
?建議服務器、云桌面、瘦終端劃分在不同的VLAN
通過服務器控制臺命令行接口顯示服務器當前狀態
show lacp???? 顯示端口聚合狀態
configured negotiated
必須顯示negotiated字樣表示與交換機成功協商成端口聚合,如果顯示configed則要檢查交換機配置
show link???? 顯示端口鏈路
eth0: no link
eth1: negotiated 1000baseT-FD flow-control, link ok
顯示所有網口的鏈路狀態,FD表示full duplex(全雙工)
show ip?????? 顯示服務器IP
current ip configuration:
interface mgt0: 192.168.3.200 255.255.255.0
default gateway: 192.168.3.254
vlan id: 3
