Error description
In man page of ifconfig, there is no such restriction documented in the order of paramters, but deleting alias IP address behaves differently how paramters are ordered. APAR IV21533 does not completely fix this issue. The problem is that the first IP address is being delete when 'alias delete' paramters are placed at the end. For example, # ifconfig en0 10.10.10.1 netmask 255.255.255.0 alias delete However, the specified alias IP address is correctly removed when alias delete is followed by IP address; # ifconfig en0 alias delete 10.10.10.1 netmask 255.255.255.0 Also, if "delete alias" is given at the end, no IP is deleted at all; # ifconfig en0 10.10.10.1 netmask 255.255.255.0 delete alias
Local fix
Do not use "alias delete" parameter at the end of ifconfig command, rather put it before IP address parameter.
Problem summary
ifconfig command deletes first IP address when 'alias delete' parameters are placed at the end. For example, # ifconfig en0 10.10.10.1 netmask 255.255.255.0 alias delete
Problem conclusion
ifconfig code is modified to delete the IP address that is passed irrespective of the order of 'alias' and 'delete' keywords.
