– 287 –
pppoe intermediate-
agent format-type
This command sets the access node identifier, generic error message, or vendor
identifier for the switch. Use the no form to restore the default settings.
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)
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.
