PPPoE Intermediate Agent

Global Configuration
Command Usage
◆ The switch inserts a tag identifying itself as a PPPoE Intermediate Agent
residing between the attached client requesting network access and the ports
connected to broadband remote access servers (BRAS). The switch extracts
access-loop information from the client’s PPPoE Active Discovery Request, and
forwards this information to all trusted ports designated by the pppoe
intermediate-agent trust command. The BRAS detects the presence of the
subscriber’s circuit-ID tag inserted by the switch during the PPPoE discovery
phase, and sends this tag as a NAS-port-ID attribute in PPP authentication and
AAA accounting requests to a RADIUS server.
◆ PPPoE IA must be enabled globally by this command before this feature can be
enabled on an interface using the pppoe intermediate-agent port-enable
command.
Example
Console(config)#pppoe intermediate-agent
Console(config)#

agent format-type
This command sets the access node identifier, generic error message, or vendor

Syntax
pppoe intermediate-agent format-type {access-node-identifier node-id-
string | generic-error-message error-message | vendor-id vendor-id-string}
no pppoe intermediate-agent format-type {access-node-identifier |
generic-error-message}
node-id-string - String identifying this switch as an PPPoE IA to the PPPoE
server. (Range: 1-48 ASCII characters)
error-message - An error message notifying the sender that the PPPoE
Discovery packet was too large.
vendor-id-string - This tag is used to pass vendor proprietary information.
The first four octets of the tag contain the vendor id and the remainder is
unspecified. The high-order octet of the vendor id is 0 and the low-order 3
octets are the SMI Network Management Private Enterprise Code of the
Vendor in network byte order, as defined in the Assigned Numbers RFC
(RFC 1700). (Range: 0-4294967295)
