Command
This is an example of an LSP ping:
Switch# ping mpls ipv4 10.131.159.251/32 destination 127.0.0.1 127.0.0.2 0.0.0.1 repeat 2
sweep 1450 1475 25
OL-23400-01
Purpose
• (Optional) reply mode {ipv4 | router-alert}—Specify the reply mode for
the echo request packet. Enter ipv4 to reply with an IPv4 UDP packet (the
default) or router-alert to reply with an IPv4 UDP packet with router
alert.
• (Optional) revision—Enter the IEFT MPLS ping draft revision number as
3 (for revision 2) or 4 (for RFC 4329 compliant).
• (Optional) size packet-size—Specify the size of the packet with the label
stack imposed as the number of bytes in each ping. The range is from 100
to 18024. The default is 100.
(Optional) source source-address—Specify the source address or the
•
name. This is the destination address in the MPLS echo response. The
default address is loopback0.
(Optional) sweep minimum maximum size-increment —Set a range packet
•
sizes to be sent, ranging from a start size to an end size. The lower
boundary of the sweep range depends on the LSP type. The range for the
minimum and maximum is 100 to 18024; the increment range is 1 to 8993.
(Optional) timeout seconds—Specify the timeout interval for an MPLS
•
request packet. The range is from 0 to 3600 seconds. The default is 2
seconds.
• (Optional) ttl time-to-live—Specify a time-to-live value. The range is from
1 to 255.
• (Optional) verbose —Display the MPLS echo reply sender address of the
• packet and return codes.
• (Optional) revision number—Enter a Cisco-TLV-revision-number, 1
through 4.
• (Optional) force-explicit-null—Add an explicit NULL label to the end of
the label stack.
(Optional) output interface interface-id—Specify the output interface for
•
the echo request.
(Optional) nexthop ip-address—Force packets to go through the specified
•
next-hop address.
• (Optional) dsmap—Request downstream mapping information from the
replying router.
• (Optional) hashkey—Specify downstream map multipath settings as
either none or ipv4 bitmap size (0 to 256).
(Optional) flags fec—Request FEC stack checking at the transit router.
