value) number of cells is reached, the MPLS packet is queued for transmission onto the pseudowire. It
is ensured that the MPLS packet MTU conforms to the configured service MTU.
The no form of this command sets max-cells to the value ’1’ indicating that no concatenation will be
performed.
Parameters cell-count — Specify the maximum number of ATM cells to be accumulated into an MPLS packet
before queueing the packet for transmission onto the pseudowire.
Values
1 — 128
Default 32
max-delay
Syntax max-delay delay-time
no max-delay [delay-time]
Context config>service>apipe>spoke-sdp>cell-concat
Description This command enables the configuration of the maximum amount of time to wait while performing
ATM cell concatenation into an MPLS packet before transmitting the MPLS packet. This places an
upper bound on the amount of delay introduced by the concatenation process. When this amount of
time is reached from when the first ATM cell for this MPLS packet was received, the MPLS packet is
queued for transmission onto the pseudowire.
The no form of this command resets max-delay to its default value.
Parameters delay-time — Specify the maximum amount of time, in hundreds of microseconds, to wait before
transmitting the MPLS packet with whatever ATM cells have been received. For example, to
bound the delay to 1 ms the user would configure 10 (hundreds of microseconds). The delay-time
is rounded up to one of the following values 1, 5, 10, 50, 100, 200, 300 and 400.
Values
1 — 400
control-word
Syntax [no] control-word
Context config>service>apipe>spoke-sdp
config>service>epipe>spoke-sdp
config>service>ipipe>spoke-sdp
Description This command indicates whether the control word is used or not. The value of the control word is
negotiated with the peer.
The control word is indicated in the label message as part of pseudowire ID FEC as the C-bit. The
control word is mandatory for Apipe service data unit and Fpipe. For other types of Apipe and Epipe
the control word is not mandatory. Therefore the usage of the control word is negotiated between the
endpoints of the pseudowire.
