IPoE and DHCP
IPoE access driven by DHCP, with MAC, IP or Option-82 identity toward RADIUS. Configuration lives in the dhcp view; the access serve-set is an explicit list and is VLAN-aware.
Configuration
Mode both serves DHCP and IPoE-authenticated subscribers; dhcp and ipoe restrict to one; off disables IPoE entirely, leaving PPPoE only. With no interface listed, nothing is served.

Subscriber identity
dhcp auth selects what becomes the RADIUS User-Name: the client MAC (default), the IP, the DHCP Option-82 circuit and remote ID inserted by the access node, or none. MAC format is configurable because RADIUS realms differ on colon, hyphen and bare forms.
