PPPoE IA typical application 
Both host and BAS server run PPPoE protocol, they are connected by layer 2 ethernet, switch 
enables PPPoE Intermediate Agent function. 
Typical configuration (1) 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 circuit ID as aaaa, remote ID as xyz for port ethernet1/3. 
Switch(config-if-ethernet1/3)#pppoe  intermediate-agent  circuit-id 
aaaa 
Switch (config-if-ethernet1/3)#pppoe intermediate-agent remote-id xyz 
circuit-id  value  is  ”abcd  eth  01/002:0001”,  remote-id  value 
is ”0a0b0c0d0e0f” for the added vendor tag of port ethernet1/2. 
circuit-id  value  is  ”aaaa”,  remote-id  value  is  ”xyz”  for  the  added 
vendor tag of port ethernet1/3. 
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
