MC-LAG 對等應處於作用中或待命模式。作用中或待命是控制面板的概念。然而在數據層面中,每個 MC-LAG 對等者都會根據角色而個別決定數據轉送路徑。
MC-LAG 角色是由對等根據 IPV4 來源 ip 和對等 IP 設定而決定。
- 如果來源ip少於對等ip,則裝置會變成作用中
- 如果來源ip大於對等ip,則裝置會變成待命
注意:作用中或待命角色不受同儕作業狀態或對等連結連線狀態的獨立。如果 Active MC-LAG 對等正在重新啟動,待命狀態不會變成 Active (反之亦然)。
例如:假設 Switch-1 使用來源 IP 10.0.0.1,而 Switch-2 具有來源 IP 10.0.0.2。
Switch-1 的MC-LAG組態
Swicth-1# show running-configuration mclag ! mclag domain 1 source-ip 10.0.0.1 peer-ip 10.0.0.2 peer-link PortChannel1 mclag-system-mac xx:xx:xx:xx:xx:xx keepalive-interval 1 Swicth-1# show running-configuration mclag Domain ID : 1 Role : active Session Status : up Peer Link Status : up Source Address : 10.0.0.1 Peer Address : 10.0.0.2 Peer Link : PortChannel1 Keepalive Interval : 1 secs Session Timeout : 30 secs Delay Restore : 300 secs System Mac : xx:xx:xx:xx:xx:xx Mclag System Mac : xx:xx:xx:xx:xx:xx
由於 Switch-1 的來源 ip (10.0.0.1) 比對等 ip (10.0.0.2) 較低,其所扮演的作用中角色。
Switch-2 的MC-LAG組態
Swicth-2# show running-configuration mclag ! mclag domain 1 source-ip 10.0.0.2 peer-ip 10.0.0.1 peer-link PortChannel1 mclag-system-mac xx:xx:xx:xx:xx:xx keepalive-interval 1 Swicth-2# show running-configuration mclag Domain ID : 1 Role : standby Session Status : up Peer Link Status : up Source Address : 10.0.0.2 Peer Address : 10.0.0.1 Peer Link : PortChannel1 Keepalive Interval : 1 secs Session Timeout : 30 secs Delay Restore : 300 secs System Mac : xx:xx:xx:xx:xx:xx Mclag System Mac : xx:xx:xx:xx:xx:xx
由於交換器-2 的來源 ip (10.0.0.2) 高於對等 ip (10.0.0.1),其擔任待命角色。
