VLL Service Configuration Commands

max-cells
Syntax max-cells cell-count
no max-cells [cell-count]
Context
config>service>apipe>spoke-sdp>cell-concat
Description This command enables the configuration of the maximum number of ATM cells to accumulate into an
MPLS packet. The remote peer will also signal the maximum number of concatenated cells it is
willing to accept in an MPLS packet. When the lesser of (the configured value and the signaled
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 1
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
Default 400
