When connecting two Fibre Channel switches using different domain IDs, which of the following would be used?
Options
- AISL
- BDSL
- CTrunking only
- DPort channel
Explanation
To connect two Fibre Channel switches operating with different domain IDs and allow them to function as a single logical fabric, a specific type of link is utilized.
Common mistakes.
- B. DSL (Digital Subscriber Line) is a technology for internet access over copper phone lines and is completely unrelated to Fibre Channel networking.
- C. While ISLs can be trunked (multiple physical links bundled into a single logical ISL), 'trunking only' is an incomplete answer as it describes a feature applied to an ISL, not the fundamental link type itself.
- D. A port channel, or link aggregation group, is a concept primarily used in Ethernet networks to bundle multiple physical links; the equivalent function for Fibre Channel switch-to-switch connectivity is achieved via ISLs, which can then be trunked.
Concept tested. Inter-Switch Link (ISL) in Fibre Channel
