When erasing or copying port config, user can select specific attribute to erase/copy. If user enter zero-length string, 0x00 (all bits are not set) or 0xFF (all bits are set) indicates all attributes are selected, in this situation, system will perform erase/copy all configurations. When erasing multiple ports from different interfaces, only check each interface with their attributes bit to perform config erasing, so does config copy. Config erase example sysTarget = 201 (voip port 1) 301 (dsl port 1) sysAttributeSelect = # 0x00 0x00 0x00 0x00 0x00 0x80 (voip-alarm) In this case, system will erase all config setting of dsl port 1, only remove voip alarm related setting from voip port 1. Config copy example sysSource = 201 (voip port 1) sysTarget = 202 (voip port 2) sysAttributeSelect = # 0x20 (dsl-acl) In this case, system will copy all config from voip port 1 to port 2, ignoring dsl attribute setting.
