PPPoE Intermediate Agent
– 276 –
Default Setting
◆ Access Node Identifier: IP address of the first IPv4 interface on the switch.
◆ Generic Error Message: PPPoE Discover packet too large to process. Try
reducing the number of tags added.
◆ Vendor Identifier: 3561
(This is the enterprise number assigned to the Broadband Forum.)
Command Mode
Global Configuration
Command Usage
◆ The switch uses the access-node-identifier to generate the circuit-id for PPPoE
discovery stage packets sent to the BRAS, but does not modify the source or
destination MAC address of these PPPoE discovery packets.
◆ The vendor-specific tag is used to pass vendor proprietary information. The
first four octets of this tag value contain the vendor identifier 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 Assigned Numbers RFC 1700.
◆ These messages are forwarded to all trusted ports designated by the pppoe
intermediate-agent trust command.
