Aggregated Links | 23 |
■If ports of a different speed are aggregated together, the higher speed links carry the traffic. The lower speed links only carry the traffic if the higher speed links fail.
■The aggregated link does not support security.
■Member links must retain the same groupings at both ends of an aggregated link. For example, the configuration in Figure 2 will not work as Switch A has one aggregated link defined whose member links are then split between two aggregated links defined on Switches B and C.

When using an aggregated link, note that:
■To gather statistics about an aggregated link, you must add together the statistics for each port in the aggregated link.
■If you wish to disable a single member link of an aggregated link, you must first physically remove the connection to ensure that you do not lose any traffic, before you disable both ends of the member link separately. If you do this, the traffic destined for that link is distributed to the other links in the aggregated link.
If you do not remove the connection and only disable one end of the member link port, traffic is still forwarded to that port by the aggregated link port at the other end. This means that a significant amount of traffic may be lost.
■Before removing all member links from an aggregated link, you must disable all the aggregated link member ports or disconnect all the links, except one — if you do not, a loop may be created.
