—(Optional) Size of the label-switched path (LSP) ping request packet (
size bytes
through bytes). Packets are 4-byte aligned. For example, If you enter a size
65468
of 97, 98, 99, or 100, the router or switch uses a size value of 100 bytes. If you enter
a packet size that is smaller than the minimum size, an error message is displayed
reminding you of the 96-byte minimum.
—(Optional) IP address of the outgoing interface. This address is
source source-address
sent in the IP source address field of the ping request. If this option is not specified,
the default address is usually the loopback interface (
—(Optional) Automatically determine the size of the maximum transmission unit
sweep
(MTU).
v1 —(Optional) Use the type 9 Layer 2 circuit type, length, and value (TLV).
virtual-circuit virtual-circuit-id neighbor address
egress PE router or switch and the specified neighbor, testing the integrity of the
Layer 2 circuit between the ingress and egress PE routers or switches.
You must configure MPLS at the
router or switch (the router or switch receiving the MPLS echo packets) to ping a Layer
2 circuit.
In asymmetric MTU scenarios, the echo response may be dropped. For example, if the
MTU from System A to System B is 1000 bytes, the MTU from System B to System A is
500 bytes, and the ping request packet size is 1000 bytes, the echo response is dropped
because the PAD TLV is included in the echo response, making it too large.

When you enter this command, you are provided feedback on the status of your request.
An exclamation point ( ) indicates that an echo reply was received. A period (
!
that an echo reply was not received within the timeout period. An
echo reply was received with an error code. Packets with an error code are not counted
in the received packets count. They are accounted for separately.
