- Flexible circuit id syntax with identifier string and variables 254
- Gs1920 series user s guide 254
- If you do not configure a circuit id string for a vlan on a specific port or for a specific port the switch adds the user defined identifier string and variables into the agent circuit id sub option the variables can be the slot id of the pppoe client the port number of the pppoe client and or the vlan id on the pppoe packet 254

- Table 114 pppoe ia remote id sub option format 254
- Table 115 pppoe ia circuit id sub option format using identifier string and variables 254
- The 1 in the first field identifies this as an agent circuit id sub option and 2 identifies this as an agent remote id sub option the next field specifies the length of the field the switch takes the circuit id string you manually configure for a vlan on a port as the highest priority and the circuit id string for a port as the second priority in addition the switch puts the pppoe client s mac address into the agent remote id sub option if you do not specify any user defined string 254
- The identifier string slot id port number and vlan id are separated from each other by a pound key semi colon period comma forward slash or space an agent circuit id sub option example is switch 07 0123 and indicates the pppoe packets come from a pppoe client which is connected to the switch s port 7 and belong to vlan 123 254
- The tag_type is 0x0105 for vendor specific tags as defined in rfc 2516 the tag_len indicates the length of value i1 and i2 the value is the 32 bit number 0x00000de9 which stands for the adsl forum iana entry i1 and i2 are pppoe intermediate agent sub options which contain additional information about the pppoe client 254
- There are two types of sub option agent circuit id sub option and agent remote id sub option they have the following formats 254
