The following table describes the labels in this screen.

Use this screen to specify whether individual ports are trusted or untrusted ports
and have the Switch add extra information to PPPoE discovery packets from PPPoE
clients on a per-port basis.
Table 100 Advanced Application > PPPoE > Intermediate Agent
LABEL DESCRIPTION
Active Select this option to enable the PPPoE intermediate agent globally on the
Switch.
access-node-
identifier Enter up to 20 ASCII characters to identify the PPPoE intermediate agent.
Hyphens (-) and spaces are also allowed. The default is the Switch’s host
name.
circuit-id Use this section to configure the Circuit ID field in the PADI and PADR
packets.
The Circuit ID you configure for a specific port or for a specific VLAN on a
port has priority over this.
The Circuit ID you configure for a specific port (in the Advanced
Application > PPPoE > Intermediate Agent > Port screen) or for a
specific VLAN on a port (in the Advanced Application > PPPoE >
Intermediate Agent > Port > VLAN screen) has priority over this. That
means, if you also want to configure PPPoE IA Per-Port or Per-Port Per-
VLAN setting, leave the fields here empty and configure circuit-id and
remote-id in the Per-Port or Per-Port Per-VLAN screen.
Active Select this option to have the Switch add the user-defined identifier string
and variables (specified in the option field) to PADI or PADR packets from
PPPoE clients.
If you leave this option unselected and do not configure any Circuit ID
string (using CLI commands) on the Switch, the Switch will use the string
specified in the access-node-identifier field.
identifier-
string
Specify a string that the Switch adds in the Agent Circuit ID sub-option.
You can enter up to 53 ASCII characters. Spaces are allowed.
option Select the variables that you want the Switch to generate and add in the
Agent Circuit ID sub-option. The variable options include sp, sv, pv and
spv which indicate combinations of slot-port, slot-VLAN, port-VLAN and
slot-port-VLAN respectively. The Switch enters a zero into the PADI and
PADR packets for the slot value.
delimiter Select a delimiter to separate the identifier-string, slot ID, port number
and/or VLAN ID from each other. You can use a pound key (#), semi-
colon (;), period (.), comma (,), forward slash (/) or space.
Apply Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
