OctetString
Indicates the list of the extend frame standard ports in the VLAN. If the VLAN contains a port, the corresponding bit of the port is set to 1. The value of hwVlanPortsExtendFrame is mixed encoding of the index and octet string. Encoding area, which specifies the index of the FrameId and SlotId, consisting of 4 characters and 2 characters respectively. Port area, which is represented in octet string format and occupies 16 characters. One bit in each octet indicates one port, so 8 octet means 64 ports in a slot. When a bit is set to 0, it indicates that the corresponding port does not belong to this VLAN. When a bit is set to 1, it indicates that the corresponding port belongs to this VLAN. The order is as follows: If a extend frame has a port that belongs to a VLAN, the port in the corresponding frame and slot are represented by octet strings. The maximum number of ports in a slot is 64, so the ports need to occupy eight octets. The order, from left to right, is presented as eight groups, 0-7, 8-15, 16-23, 24-31, 32-39, 40-47, 48-55, and 56-63. In each octet, the PortId in ascending order are presented from low bit to high bit. For example, ports 0/11/2 and 0/11/3 need to added to the same VLAN. The values of hwVlanPortsExtendFrame of the upstream ports (ports 1/02/2 and 1/02/3 and 1/03/1) to be added is calculated as follows: For ports 0-7 in slot 02 in frame 1, their corresponding character string positions are 76543210, and after ports 1/02/2 and 1/02/3 are added, the bitmap is 00001100 00000000 00000000 00000000 00000000 00000000 00000000 00000000, and the string is (HEX) 0C 00 00 00 00 00 00 00. After the FrameId (2 Octet) and SoltId (1 Octet) are added at the front, the string is 0001 02 0c 00 00 00 00 00 00 00. In the same way, 1 / 03 / 1 is encoded as 0001 03 02 00 00 00 00 00 00 00. Assuming that the other slots do not have any port that is added to the VLAN, The slot information is not filled in. Therefore, the length of the code is variable, but usually is an integer multiple of 22 characters.finally, the string is 00 01 02 0C 00 00 00 00 00 00 00 00 01 03 02 00 00 00 00 00 00 00 Under special circumstances, none port in VLAN is described by '0',which is just one character.
