Data Link Layer Protocols and Services

With NetQ, a user can monitor OSI Layer 2 devices and protocols, including switches, bridges, link control, and physical media access. Keeping track of the various data link layer devices in your network ensures consistent and error-free communications between devices.

It helps answer questions such as:

  • Is a VLAN misconfigured?
  • Is MLAG configured correctly?
  • Is LLDP running on all of my devices?
  • Is there an STP loop?
  • What is the status of interfaces on a device?
  • Where has a given MAC address lived in my network?
