Bug ID 1671645: Interfaces not properly mapped after switching port profiles from 8x10 to 4x25

Last Modified: Oct 19, 2025

Affected Product(s):
BIG_IP_NEXT(VE/HW) TMOS(all modules)

Known Affected Versions:
20.3.0

Opened: Sep 17, 2024

Severity: 2-Critical

Symptoms

When a BIG-IP Next instance is initially onboarded using a 4x25 port profile, switching to an 8x10 port profile results in improper interface mapping.

Impact

Interfaces from the original 4x25 port profile remain active even after attempting to switch to the 8x10 port profile.

Conditions

This issue occurs when a BIG-IP Next instance, initially configured with a 4x25 port profile, is later modified to use an 8x10 port profile.

Workaround

Avoid changing a BIG-IP Next instance from a 4x25 to an 8x10 port profile. Instead, onboard a new instance directly with the 8x10 port profile configuration.
