Subscriber Services: Dynamic variable to create interface sets for a passive optical network

You can use the predefined variable $junos-pon-id-interface-set-name to extract a portion of the DHCPv4 (Option 82, suboption 2) or DHCPv6 (Option 37) agent remote ID string inserted by the optical line terminal (OLT). The OLT must format the string with a pipe symbol (|) as the delimiter between substrings. The substring consists of the characters following the last delimiter in the agent remote ID string. The contents of the substring are determined by the customer, but can include the name and port of the OLT accessed by the CPE optical network terminal (ONT). After extraction, this substring is used as the name of an interface set and as an identifier to discriminate among individual customer circuits to be aggregated into the interface set.
