Syntax

tx-connect-speed-method method;

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 11.4.

Options ancp, pppoe-ia-tag, and static introduced in Junos OS Release 13.1.

Description

Specify the method that determines the connection speed values sent from the LAC to the LNS in Incoming-Call-Connected (ICCN) messages. The transmit speed is conveyed in AVP 24 (Tx Connect Speed ) and the receive speed is conveyed in AVP 38 (Rx Connect Speed). Both values are in bits per seconds (BPS).

Default

static

Options

method

—

Method used to derive the connection speed values.

ancp—The speed is derived from the configured ANCP value for the underlying interface. You can change this rate after a subscriber has logged in, but those changes do not affect the actual rate used by the LNS. The ancp method gets the highest preference among the methods configured.
pppoe-ia-tags—PPPoE IA tags sent from the DSLAM to the LAC. This speed value transmitted when a subscriber logs in and it cannot be subsequently changed. This value is used when the ancp value is not available. This speed does not apply to the subscribers that are already logged in; it is effective only for subscribers that log in after this setting has been saved. AVP 24 is the value of Actual-Data-Rate-Downstream (VSA 26-129). AVP 38 is the value of Actual-Data-Rate-Upstream (VSA 26-130), and is sent only when the VSA values differ.
Note: This rate does not affect the subscribers already logged in; however, new subscribers inherit the new rate.
static—The speed is derived from the recommended (advisory) shaping rate configured on the PPPoE logical interface underlying the subscriber interface. If the advisory speed is not configured on the underlying interface, then the actual port speed is used. The default method, when no other methods yield a value, is the static method or the advisory speed method. If the advisory speed is not configured, then the actual port speed is used. For ge and xe interfaces, the speed value is set to 10,000,000 and for ae interfaces, the speed value is set to 0 and sent in both AVP 24 and AVP 38.
