DSCP / CoS Converter

DSCP / CoS Converter turns QoS markings into the formats engineers see across routers, switches, firewalls, and packet captures.

What It Converts

  • DSCP decimal values.
  • ToS byte values.
  • Class Selector and Assured Forwarding names.
  • CoS-style priority references.
  • Common voice marking EF.

When To Use It

Use it when comparing QoS policy, packet captures, phone configs, firewall rules, or carrier handoff requirements.

Troubleshooting Notes

  • Marking packets does not guarantee priority unless the network honors it.
  • Some providers remark or strip DSCP.
  • Capture at multiple points if QoS changes along the path.
