Extreme Switch - How to check GBIC (SFP, SFP+) information

When working with Extreme EXOS switches, it’s often necessary to check the details of the optical transceivers connected to the ports. Here's how you can do it effectively.

The following command will show the optic details for all ports connected to a Summit switch:

debug hal show optic-info

For a more targeted approach within a Summit stack, specify the slot and port numbers:


Slot-1 switch-exos-stack # debug hal show optic-info slot 1 port 50
Port 50

SD-WAN Terminology for Extreme SD-WAN

 
Software-Defined Wide Area Networking (SD-WAN) has emerged as a game-changer for modern enterprise networks, offering improved application performance, security, and operational efficiency. However, the terminology surrounding SD-WAN can often seem overwhelming, especially for those new to the technology. In this article, I'll demystify some of the key terms used in the context of Extreme Networks' SD-WAN solution, helping you navigate this space with confidence.
