ansmit | receive | both | resync number}
no sequencing {tr
ansmit | receive | both | resync number}
Syntax Description

Command Modes Pseudowire class configuration
Command History
Usage Guidelines When you enable sequencing using any of the available options, the sending of sequence numbers is
a
utomatically enabled and the remote provider edge (PE) peer is requested to send sequence numbers.
Out-of-order packets received on the pseudowire are dropped only if you use the sequencing receive or
sequencing both command.
transmit Updates the Sequence Number field in the headers of data packets sent over
t
he pseudowire according to the data encapsulation method that is used.
receive Keeps the value in the Sequence Number field in the headers of data packets
re
ceived over the pseudowire. Out-of-order packets are dropped.
both Enables both the tr
ansmit and receive options.
resync Enables the reset of packet sequencing after the disposition router receives
a
specified number of out-of-order packets.
number The number of out-of-order packets that cause a reset of packet sequencing.
The
range is 5 to 65535.
