Failover Group

Figure 3-7 (page 30) shows a sample failover group (LAN_MONITOR mode) configuration. This configuration provides high availability network access with an active link and a standby link, and has the following characteristics:

•Dual switches or hubs are not required. However, dual switches and hubs provide a more reliable network environment by removing the switch or hub as a single point of failure. If two switches or hubs are used, there must be a data path between them to allow them to be on the same subnet.

•You can connect failover groups to any switch or hub.

•The link partner does not require trunking to be enabled.
