Aggregation Switch Interface

3ad link aggregation enables you to group Ethernet interfaces to form a single link layer interface, also known as a link aggregation group (LAG) or bundle. An aggregation switch is a network device that consolidates traffic from multiple access switches, wireless access points, or other edge devices and forwards it to core switches or routers. Amounts or summary statistics are used in place of atomic data rows, which are often collected from several sources when data is aggregated. "Campus Networks Typical Configuration Examples" provides typical campus network networking modes and a variety of deployment examples. [pdf]

Which ports are aggregation ports on a switch

With the modes balance-rr, balance-xor, broadcast and 802.3ad, all physical ports in the link aggregation group must reside on the same logical switch, which, in most common scenarios, will leave a single point of failure when the physical switch to which all links are connected goes offline. The modes active-backup, balance-tlb, and balance-alb can also be set up with two or more switches. But after failover (like all other modes), in some cases, active sessions may fail (due to ARP problems) an. [pdf]
