MPLS LSP Ping, Traceroute, and AToM VCCV
Description
Size of the packet with the label stack imposed.
Specified with the size packet-size keyword and
argument. The default size is 100.
For use with the MPLS LSP Ping feature only.
Padding (the pad time-length-value [TLV]) is used
as required to fill the datagram so that the MPLS echo
request (User Datagram Protocol [UDP] packet with
a label stack) is the size specified. Specify with the
pad pattern keyword and argument.
For use with the MPLS LSP Ping feature only.
Parameter that enables you to send a number of
packets of different sizes, ranging from a start size to
an end size. This parameter is similar to the Internet
Control Message Protocol (ICMP) ping sweep
parameter. The lower boundary on the sweep range
varies depending on the label switched path (LSP)
type. You can specify a sweep size range when you
use the ping mpls command. Use the sweep minimum
maximum size-increment keyword and arguments.
For use with the MPLS LSP Ping feature only.
Number of times to resend the same packet. The
default is 5 times. You can specify a repeat count
when you use the ping mpls command. Use the
repeat count keyword and argument.
For use with the MPLS LSP Ping feature only.
Routable address of the sender. The default address
is loopback0. This address is used as the destination
address in the Multiprotocol Label Switching (MPLS)
echo response. Use the source source-address
keyword and argument.
For use with the MPLS LSP Ping and Traceroute
features.
