Configuring PPPoE IA
Interface Settings
Use the IP Service > PPPoE Intermediate Agent (Configure Interface) page to enable
PPPoE IA on an interface, set trust status, enable vendor tag stripping, and set the
circuit ID and remote ID.
Parameters
These parameters are displayed:
Interface – Port or trunk selection.
PPPoE IA Status – Enables the PPPoE IA on an interface. (Default: Disabled)
Note that PPPoE IA must also be enabled globally on the switch for this
command to take effect.
Trust Status – Sets an interface to trusted mode to indicate that it is connected
to a PPPoE server. (Default: Disabled)
Set any interfaces connecting the switch to a PPPoE Server as trusted.
Interfaces that connect the switch to users (PPPoE clients) should be set as
untrusted.
At least one trusted interface must be configured on the switch for the
PPPoE IA to function.
Vendor Tag Strip – Enables the stripping of vendor tags from PPPoE Discovery
packets sent from a PPPoE server. (Default: Disabled)
This parameter only applies to trusted interfaces. It is used to strip off vendor-
specific tags (which carry subscriber and line identification information) in
PPPoE Discovery packets received from an upstream PPPoE server before
forwarding them to a user.
Circuit ID – String identifying the circuit identifier (or interface) on this switch
to which the user is connected. (Range: 1-10 ASCII characters; Default: Unit/
Port:VLAN-ID, or 0/Trunk-ID:VLAN-ID)
The PPPoE server extracts the Line-ID tag from PPPoE discovery stage
messages, and uses the Circuit-ID field of that tag as a NAS-Port-ID attribute
in AAA access and accounting requests.
