Opened: May 20, 2015

Severity: 3-Major

Symptoms

Current configuration validation will allow a user to delete the last (only remaining) IP address on a GTM server. However, since a GTM server cannot be created/loaded without at least one IP address, the configuration will fail to load.

Impact

Configuration load will fail. If the GTMs are in a sync group, this will also break sync because the config change cannot be loaded by any GTM.

Conditions

User has deleted the last IP address on a GTM server.

Workaround

User must either delete the server from the config if it has no more valid IPs, or must add at least one IP to the server's IP address list.

Fix Information

Extended MCPD validation to ensure any deleted GTM link/GTM server addresses do not leave parent objects without addresses.
