MLAG group 100：用於客戶網路連線，這些介面直接連線至客戶交換器。每一個 Hare 和 Rabbit 都必須至少連接一個連接埠上行鏈路。狀態應為「Connected」，表示連結已在實體層上啟動且處於作用中狀態。此群組具有多個介面群組 (Ethernet 連接埠 1 至 8)。
節點連線 (Et9 - Et 16)：在標準 Gen 2 機架上，每個節點 1 slave-0 介面都連接到 Rabbit 連接埠乙太網路 9，而其對應的 slave-1 會連接到 Hare 上的相同連接埠。每個節點都有其自己的 MLAG 群組識別 (1 為 provo，2 為 sandy 等)。為確保節點連結已上線，Hare 和 Rabbit 交換器端的狀態應為「connected」。
Ethernet 45 - 48：是 mlag 的同儕連線，這是 Hare 和 Rabbit 之間的後端連線，這些連線應隨時保持連線，以確保交換器匯總通訊協定可如預期運作。
- 特定介面檢查 (詳細資料);
若要更深入瞭解個別連接埠的詳細資料，可以使用下列命令。以下範例檢查 ethernet 9
命令：
命令：
# sh int Ethernet 9
範例：
hare>sh int Ethernet 9

透過此命令，我們可以查看特定介面的進一步詳細資料：
- 連接埠狀態應為已連線，線路通訊協定應處於上線狀態。如果連接埠從硬體方面觀察為故障，我們可能會看到連接埠狀態為離線。
- 您也可以從此輸出驗證MAC 位址。這是每個連接埠擁有的唯一硬體位址。
- 雙工和速度是驗證的重要事項。應一律進行全雙工協商，若出現半雙工便表示有協商問題，必須進行調查。
- 連接埠連續運作時間有助於驗證穩定性，萬一連結出現變動，運作時間將持續重設。
- 計數器可提供的重要統計資料，連接埠上的 CRC、錯誤和碰撞不應增加。如果有所增加，代表發生問題，可能會對效能造成影響。
