MPLS Commands
The keyword is used to specify the source IP address used in the MPLS echo request. This is the IP
from
address used by the target LSR will use to send the MPLS echo reply. If not specified, the OSPF/ISIS
router ID is used.
The optional keyword is used to specify the Experimental bits in the MPLS shim header of the
exp
MPLS echo request. Valid exp_value parameter values are 0 through 7. The default value is 0.
The optional keyword is used to specify the 802.1p bits in the MPLS echo request. Valid
dot1p
parameter values are 0 through 7. The default value is 0.
dot1p_value
The optional
continuous
key can interrupt the operation.
The optional keyword specifies the number of bytes to include as payload data in the MPLS ping
size
packet. If no

type of MPLS ping packet sent, but the total size of the MPLS ping packet cannot exceed the configured
jumbo packet size, if jumbo frames are enabled, or 1518 if jumbo frames are disabled. If the
parameter is specified, the size of the packet will increment by one byte for each new MPLS echo
request sent. The next MPLS echo request is not sent until the MPLS echo response for the previous
packet is received. This is useful for detecting interface MTU mismatch configurations between LSRs.
The switch ceases sending MPLS echo requests when the specified
MPLS ping is user interrupted, or a MPLS echo response is not received after four successive retries.
The optional
reply-mode
When the option is specified, the MPLS echo reply is routed back to the sender via an IPv4 packet

with the IP Router Alert option. When the
back to the sender via an IPv4 packet over an LSP. If there is no return LSP available, the MPLS echo
reply is not sent. This option is useful for determining if there is a failure along the return LSP. If the
is not specified, the mpls reply mode is used.
