The optional
exp
keyword is used to specify the Experimental bits in the MPLS shim header of the
MPLS echo request. Valid exp_value parameter values are 0 through 7. The default value is 0.
The optional
dot1p
keyword is used to specify the 802.1p bits in the MPLS echo request. Valid
dot1p_value
parameter values are 0 through 7. The default value is 0.
The optional
continuous
keyword specifies that MPLS ping packets be sent continuously. Pressing any
key can interrupt the operation.
The optional
size
keyword specifies the number of bytes to include as payload data in the MPLS ping
packet. If no
start_size
parameter is specified, the size of the payload data is eight bytes. The
minimum valid
start_size
value is one. The maximum start_size value is variable, depending on the
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
end_size
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
end_size value
is reached, the
MPLS ping is user interrupted, or a MPLS echo response is not received after four successive retries.
The optional
reply-mode
keyword is used to specify the return path for the MPLS echo response.
When the
ip
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
mpls
option is specified, the MPLS echo reply is switched
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
reply-mode
is not specified, the mpls reply mode is used.
