Typical configuration (2) in the following:
Step1: Switch enables global PPPoE IA function, MAC as 0a0b0c0d0e0f.
Switch(config)#pppoe intermediate-agent
Step2: Configure port ethernet1/1 which connect server as trust port, and configure vendor tag
strip function.
Switch(config-if-ethernet1/1)#pppoe intermediate-agent trust
Switch(config-if-ethernet1/1)#pppoe intermediate-agent vendor-tag strip
Step3: Port ethernet1/2 of vlan1 and port ethernet1/3 of vlan 1234 enable PPPoE IA function of
port.
Switch(config-if-ethernet1/2)#pppoe intermediate-agent
Switch(config-if-ethernet1/3)#pppoe intermediate-agent
Step4: Configure pppoe intermediate-agent access-node-id as abcd.
Switch(config)#pppoe intermediate-agent type tr-101 circuit-id access-node-id abcd
Step5: Configure pppoe intermediate-agent identifier-
string as “efgh”, combo mode as spv,
delimiter of Slot ID and Port ID as “#”, delimiter of Port ID and Vlan ID as “/”.
Switch(config)#pppoe intermediate-agent type tr-101 circuit-id identifier-string efgh option spv
delimiter # delimiter /
Step6: Configure circuit-id value as bbbb on port ethernet1/2.
Switch(config-if-ethernet1/2)#pppoe intermediate-agent circuit-id bbbb
Step7: Configure remote-id as xyz on ethernet1/3.
Switch(config-if-ethernet1/3)#pppoe intermediate-agent remote-id xyz
circuit-
id value is ”bbbb”, remote-id value is ”0a0b0c0d0e0f” for the added vendor tag of port
ethernet1/2.
circuit-
id value is ”efgh eth 01#003/1234”, remote-id value is ”xyz” for the added vendor tag of
port ethernet1/3.
47.4 PPPoE Intermediate Agent
Troubleshooting
Only switch enables global PPPoE intermediate agent firstly, this function can be run on port.
Configure a trust port at least, and this port can connect to server.
vendor tag strip function must be configured by trust port.
Circuit-id override priority is: pppoe intermediate-agent circuit-id < pppoe intermediate-agent
identifier-string option delimiter < pppoe intermediate-agent access-node-id.
