The LSP-EXP mappings on the receive network interface controls the mapping back to the
internal forwarding class used by the far-end 7x50 SR that receives the message request. The
egress mappings of the egress network interface on the far-end router controls the forwarding
class markings on the return reply message. The LSP-EXP mappings on the receive network
interface controls the mapping of the message reply back at the originating SR.
Default be
Values be, l2, af, l1, h2, ef, h1, nc
profile {in | out} — The profile state of the MPLS echo request encapsulation.
Default out
timeout seconds — The timeout parameter, in seconds, expressed as a decimal integer. This value is
used to override the default timeout value and is the amount of time that the router will wait for a
message reply after sending the message request. Upon the expiration of message timeout, the
requesting router assumes that the message response will not be received. A ‘request timeout’
message is displayed by the CLI for each message request sent that expires. Any response
received after the request times out will be silently discarded.
Default 5
Values 1 — 10
interval seconds — The interval parameter in seconds, expressed as a decimal integer. This
parameter is used to override the default request message send interval and defines the minimum
amount of time that must expire before the next message request is sent.
If the interval is set to 1 second, and the timeout value is set to 10 seconds, then the maximum
time between message requests is 10 seconds and the minimum is 1 second. This depends upon
the receipt of a message reply corresponding to the outstanding message request.
Default 1
Values 1 — 10
size octets — The VCCV ping echo request packet size in octets, expressed as a decimal integer. The
request payload is padded with zeroes to the specified size.
Default 88
Values 88 — 9198
count send-count — The number of messages to send, expressed as a decimal integer. The count
parameter is used to override the default number of message requests sent. Each message request
must either timeout or receive a reply before the next message request is sent. The message
interval value must be expired before the next message request is sent.
Default 1
Values 1 — 100
ttl vc-label-ttl — Specifies the time-to-live value for the vc-label of the echo request message. The
outer label TTL is still set to the default of 255 regardless of this value.
