Opened: May 17, 2021

Severity: 3-Major

Symptoms

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".

Impact

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.

Conditions

- 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.).

Workaround

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.
