ipv4 |
Specifies the destination type as a LDP IPv4 address. |
destination-address |
Address prefix of the target to be tested. |
/destination-mask-length |
Number of bits in the network mask of the target address. The slash is required. |
destination |
(Optional) Specifies a network 127 address. |
address-start |
(Optional) Beginning network 127 address. |
address-end |
(Optional) Ending network 127 address. |
increment |
(Optional) Number by which to increment the network 127 address. |
ttl time-to-live |
(Optional) Specifies a time-to-live (TTL) value. The default is 225 seconds. |
pseudowire |
Specifies the destination type as an Any Transport over MPLS (AToM) virtual circuit (VC). |
ipv4-address |
IPv4 address of the AToM VC to be tested. |
vc-id |
Specifies the VC identifier of the AToM VC to be tested. |
segment segment-number |
(Optional) Specifies a segment of a multisegment pseudowire. |
traffic-eng |
Specifies the destination type as an MPLS-TE tunnel. |
tunnel-interface |
Tunnel interface to be tested. |
tunnel-number |
Tunnel interface number. |
revision {1 | 2 | 3 | 4 |
(Optional) Selects the type, length, values (TLVs) version. |
source source-address |
(Optional) Specifies the source address or name. The default address is loopback0. This address is used as the destination address in the MPLS echo response. |
repeat count |
(Optional) Specifies the number of times to resend the same packet. The range is from 1 to 2147483647. The default is 1. |
timeout seconds |
(Optional) Specifies the timeout interval in seconds for an MPLS request packet. The range is from 0 to 3600. The default is 2 seconds. |
size packet-size |
(Optional) Specifies the size of the packet with the label stack imposed. Packet size is the number of bytes in each ping. The range is from 40 to 18024. The default is 100. |
sweep |
(Optional) Enables you to send a number of packets of different sizes, ranging from a start size to an end size. |
minimum |
(Optional) Minimum or start size for an MPLS echo packet. The lower boundary of the sweep range varies depending on the LSP type. The default is 100 bytes. |
maximum |
(Optional) Maximum or end size for an echo packet. The default is 17,986 bytes. |
size-increment |
(Optional) Number by which to increment the echo packet size. The default is 100 bytes. |
pad pattern |
(Optional) The pad TLV used to fill the datagram so that the MPLS echo request is the specified size. The default is 0xABCD. |
reply dscp dscp-value |
(Optional) Provides the capability to request a specific class of service (CoS) in an echo reply by providing a differentiated services code point (DSCP) value. |
reply pad-tlv |
(Optional) Tests the ability of the sender of an echo reply to support the copy pad TLV to echo reply. |
reply mode {ipv4 | router-alert} |
(Optional) Specifies the reply mode for the echo request packet. ipv4—Reply with an IPv4 UDP packet (default). router-alert—Reply with an IPv4 UDP packet with router alert. |
interval ms |
(Optional) Specifies the time, in milliseconds (ms), between successive MPLS echo requests. This parameter allows you to pace the transmission of packets so that the receiving router does not drop packets. Default is 0. |
exp exp-bits |
(Optional) Specifies the MPLS experimental field value in the MPLS header for an MPLS echo reply. Valid values are from 0 to 7. Default is 0. |
verbose |
(Optional) Displays the MPLS echo reply sender address of the packet and displays return codes. |
revision tlv-revision-number |
(Optional) Cisco TLV revision number. |
force-explicit-null |
(Optional) Forces an explicit null label to be added to the MPLS label stack even though the label was unsolicited. |
output interface tx-interface |
(Optional) Specifies the output interface for echo requests. |
nexthop ip-address |
(Optional) Causes packets to go through the specified next-hop address. |
dsmap |
(Optional) Interrogates a transit router for downstream mapping information. |
hashkey {none | ipv4 bitmap bitmap-size |
(Optional) Allows you to control the hash key and multipath settings. Valid values are: none—There is no multipath (type 0). ipv4 bitmap bitmap-size—Size of the IPv4 addresses (type 8) bitmap. If you enter the none keyword, multipath LSP traceroute acts like an enhanced LSP traceroute; that is, it uses multipath LSP traceroute retry logic and consistency checking. |
flags fec |
(Optional) Allows Forward Equivalence Class (FEC) checking on the transit router. A downstream map TLV containing the correct received labels must be present in the echo request for target FEC stack checking to be performed. Target FEC stack validation is always done at the egress router. Ensure to use this keyword in conjunction with the ttl keyword. |
