基于三層(IP)的類型為“IP”的後台服務。該類服務能同時支持TCP和UDP協議

3 layer slb
slb virtual ip <virtual name> <IP> 這個命令是用來創建基于三層協議的負載均衡操作的虛擬服務。這種虛擬服務可以同時支持TCP和UDP協議。
例 23.2. slb virtual http
slb virtual http vs1 172.16.0.3 80 Array(config)#show slb virtual http slb virtual http "vs1" 172.16.0.3 80 arp 0
slb group method <group_name> [algorithm] algorithm 在組內的後台服務中進行負載均衡的算法。可選參數,預設值為輪循(rr)。基于使用的算法,需要不同的擴展參數。下面標有"*"的算法需要擴展參數。 rr 輪循 pc 保持 Cookie* pi 保持 IP地址* hi Hash IP地址* hc Hash Cookie* ph 保持域名* pu 保持 URL* ic 插入 Cookie* rc 改寫 Cookie* ec 嵌入 Cookie* lc 最少連接數* sr 最短響應時間 hh Hash Header* sslsid SSL Session ID* chi Consistent Hash IP* prox 就近性* snmp 簡單網絡管理協議* sipcid SIP CallID* sipuid SIP UserID* chh Consistent Hash Header* hq Hash Query* hip Hash (IP+Port) *
例 23.3. slb group method
Array(config)#slb group method gm1 rr Array(config)#show slb group method slb group method "gm1" rr
slb group member <group_name> <real_name>
例 23.4. slb group member
Array(config)#slb group member gm1 rs1 Array(config)#slb group member gm1 rs2 Array(config)#show slb group member gm1 slb group member "gm1" "rs1" 1 slb group member "gm1" "rs2" 1
slb policy default "vs1" "gm1"
例 23.5. slb policy default
Array(config)#slb policy default "vs1" "gm1" Array(config)#show slb policy all slb policy default "vs1" "gm1"
這條命令允許系統管理員清空指定服務組的保持性關係表。這條命令會消除所有已經建立的保持性關係,所有使用這條命令時有提醒信息。已經建立保持連接的用戶,會被迫重新建立保持性連接。“group_name”參數,必須是採用hc、hh、ph或者pi算法的服務組。
slb group flush
