Opened: Mar 30, 2022
Severity: 3-Major


Modifications to the two default port lists are lost after a full reload of the configuration: net port-list _sys_self_allow_tcp_defaults net port-list _sys_self_allow_udp_defaults For example, delete a port from a list and it will return to the list in the running configuration after a reload.


The running configuration is wrong and deletions made to the port-list are lost. When the port list in question is used, traffic handling behavior may differ from what is expected. For example, if the port list is used in a firewall policy, ports and services may become unexpectedly allowed or disallowed after a config reload.


-- Default port list modified, and a default value from the port-list is removed. -- Configuration reload via "tmsh load sys config", loading UCS, mcpd forceload, or upgrade


Do not modify the default port lists. Create a new port list and use that instead.
