Bug ID 1019085: Network virtual-addresses fail to retain the "icmp-echo enabled" property following an upgrade or reload of the configuration from file.

Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP Install/Upgrade(all modules)

Known Affected Versions:
13.1.0,,,,,,,,, 13.1.1,,,,, 13.1.3,,,,,,, 13.1.4,, 14.1.0,,,,,, 14.1.2,,,,,,,,, 14.1.3,, 14.1.4,,,,,, 15.1.0,,,,,, 15.1.1, 15.1.2,, 15.1.3,, 15.1.4,, 15.1.5, 16.0.0,, 16.0.1,,

Fixed In:
16.1.0,,, 13.1.5

Opened: May 17, 2021

Severity: 3-Major


Network virtual-addresses default to "arp disabled" and "icmp-echo disabled". However, a BIG-IP Administrator can change these settings to "enabled", if required. Either following a software upgrade or a reload of the configuration from file, network virtual-addresses that had previously been set to "icmp-echo enabled" revert to the default of "icmp-echo disabled".


Traffic failures can occur as a result of the affected network virtual-addresses not being presented to the surrounding network as originally intended by the BIG-IP Administrator.


- One or more network virtual-addresses configured with "icmp-echo enabled". - A software upgrade or reload of the configuration from file occurs (for example, taking and restoring a UCS archive, removing the mcpd binary database and reloading the config, etc.).


Manually configure the affected virtual-addresses to "icmp-echo enabled" again. This workaround is not permanent, and the issue will occur again in the future given the right conditions.

Fix Information

Network virtual-addresses no longer lose the "icmp-echo enabled" property.
