Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
If you enable sequencing for Layer 2 pseudowires on the Cisco 7500 series routers and you issue the ip
cef distributed command, all traffic on the pseudowires is switched through the line cards.
It is useful to specify the re
sync keyword for situations when the disposition router receives many
out-of-order packets. It allows the router to recover from situations where too many out-of-order packets
are dropped.
Examples The following example shows how to enable sequencing in data packets in Layer 2 pseudowires that
w
ere created from the pseudowire class named “ether-pw” so that the Sequence Number field is updated
in tunneled packet headers for data packets that are both sent and received over the pseudowire:
Router(config)# pseudowire-class ether-pw
Router(config-pw)# encapsulation mpls
Router(config-pw)# sequencing both
The following example shows how to enable the disposition router to reset packet sequencing after it
receives 1000 out-of-order packets:
Router(config)# pseudowire-class ether-pw
Router(config-pw)# encapsulation mpls
Router(config-pw)# sequencing both
Router(config-pw)# sequencing resync 1000
