Parameter DGS-1520 Series Gigabit Ethernet Smart Managed Switch Web UI Reference Guide Description • A formatted key string is a string that should be translated before being encapsulated in the packet. A formatted key string can be contained both ASCII strings and hexadecimal values. For example, "%" +"$"+"1~32"+ "keyword"+":": o % - Indicates that the string that follows this character is a formatted key string. o "$" or "0" - (Optional) Indicates a fill indicator. This option specifies how to fill the formatted key string to meet the length option. This option can be either "$" or "0", and cannot be specified as both at the same time.  "$" - Indicates to fill the leading space (0x20).  "0" - Indicates to fill the leading 0. By default, this option is used. o 1~32 - (Optional) Indicates a length option. This specifies how many characters or bytes the translated key string should occupy. If the actual length of the translated key string is less than the length specified by this option, a fill indicator will be used to fill it. Otherwise, this length option and fill indicator will be ignored and the actual string will be used directly. o keyword - Indicates that the keyword will be translated based on the actual value of the system. The following keyword definitions specifies that a command will be refused if an unknown or unsupported keyword is detected:  devtype - The model name of the device. Only an ASCII string is allowed.  sysname - Indicates the System name of the Switch. Only an ASCII string is allowed.  ifdescr - Derived from ifDescr (IF-MIB). Only an ASCII string is allowed.  portmac - Indicates the MAC address of a port. This can be either an ASCII string or a hexadecimal value. When in the format of an ASCII string, the MAC address format can be customized using special CLI commands. When in the format of a hexadecimal value, the MAC address will be encapsulated in order in hexadecimal.  sysmac - Indicates the system MAC address. This can be either an ASCII string or a hexadecimal value. In the ASCII string format, the MAC address format can be customized using special CLI commands. In the hexadecimal format, the MAC address will be encapsulated in order in hexadecimal.  unit - Indicates the unit ID. This can be either an ASCII string or a hexadecimal value. For a standalone device, the unit ID is 0.  module - Indicates the module ID number. This can be either an ASCII string or a hexadecimal value.  port - Indicates the local port number. This can be either an ASCII string or a hexadecimal value.  svlan - Indicates the outer VLAN ID. This can be either an ASCII string or a hexadecimal value.  cvlan - Indicates the inner VLAN ID. This can be either an ASCII string or a hexadecimal value. o : - Indicates the end of the formatted key sting. If a formatted key string is the last parameter of the command, its ending character (":") can be ignored. The space (0x20) between "%" and ":" will be ignored. Other spaces will be encapsulated. • ASCII strings can be any combination of formatted key strings and 0~9, a~z, A~Z and space characters. "\" is the escape character. The special character after "\" is the character itself, for example, 82
