Stack Data Ring

This widget displays data connections between switches in your switch stack, together with the redundancy status.

Issues between switches are highlighted with red icons.

If the bandwidth status is half redundancy and has a warning icon, one or more connections are not up. On most switch models, this means bandwidth is reduced by half and a single additional ring failure will result in a severe failure such as stack partitioning.

Icon Meaning
Master switch for data.
Standby switch for data. If the master switch fails, the standby takes over operations.
