32.3.24 show linerate Command
Syntax:
show linerate <slot-port>
This command displays an ADSL port's line rate information.
The following example displays the line operating values for ADSL port 5 on the line card in slot 7.
The following table describes labels in this example.
32.3.25 show linestat Command
Syntax:
show linestat <slot-port> [data|pots]
This command displays a port's link status.
32.3.26 Tshow mac Command
Syntax:
show mac [enet1|enet2|t1|<mac>|<slot>|<slot-port>|{vid <vid1>[-<vid2>]

Table 378 Line Rate Information
LABEL DESCRIPTION
The rate fields display the transmission rates. “Line Down” indicates that the ADSL port is not connected to a
subscriber.
up/down stream Upstream refers to traffic coming into the DSL line card from the subscriber's ADSL
modem or router. Downstream refers to traffic going out from the DSL line card to the
subscriber's ADSL modem or router.
payload rate These are the data (the payload data without transport layer protocol headers and traffic)
transfer rates (in Kbps) at which the port is receiving and sending data.
actual rate These are the data transfer rates (in Kbps) at which the port is receiving and sending
data.
attainable rate These are the highest theoretically possible transfer rates (in Kbps) at which the port
could receive and send data.
noise margin These are the DSL line’s noise margins. Measured in decibels (dB).
attenuation These are the reductions in amplitude of the DSL signals. Measured in decibels (dB).
