This is a known issue, Paragon-X GUI incorrectly shows an error in the “sequenceId” column, identified with the [!]. An example is shown in the screenshot below, the the PDEL-R-FOL sequence correctly advances sequentially however each is highlighted in RED denoting an error, the same happens for the Announce messages.
The root cause is due to way Paragon-X evaluates Sequence ID’s for Signalling, Announce, and Peer Delay Response Follow Up (PDEL-R-FOL) message types. The Sequence ID for all these message types are compared with each other, instead of being compared with messages of the same type as happens for the other message types (e.g. SYNC, PDEL_REQ, etc.) in the flow.
Calnex PFV Application correctly reports no error, the workaround is to use PFV for correct field verification of Peer Delay Response Follow Up Messages.
