Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
revision {1 | 2 | 3 | 4} (Optional) Selects the type, length, values (TLVs) version of the
implementation. Use the revision 4 default unless attempting to
interoperate with devices running Cisco IOS Release 12.0(27)S1 or
12
.0(27)S2. If you do not select a revision keyword, the software uses the
latest version.
See Ta
ble 12 in the “Revision Keyword Usage” section of the “Usage
Guidelines” section for information on when to select the 1, 2, 3,
and 4
keywords.
source sour
ce-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 c
ount (Optional) Specifies the number of times to resend the same packet. The
range is from 1 to 2147483647. The default is 1. If you do not enter the
re
peat keyword, the software resends the same packet five times.
timeout se
conds (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 pa
cket-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,
r
anging from a start size to an end size. This parameter is similar to the
Internet Control Message Protocol (ICMP) ping sweep parameter.
minimum (Optional) Minimum or start size for an MPLS echo packet. The lower
bo
undary 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 1
00 bytes.
pad pa
ttern (Optional) The pad TLV is used to fill the datagram so that the MPLS echo
request (User Datagram Protocol [UDP] packet with a label stack) is the
specified size. The default is 0xABCD.
reply dscp dsc
p-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.
The echo reply is returned with the IP header type of service (ToS) byte set
to
the value specified in the reply dscp command.
reply pad-tlv (Optional) Tests the ability of the sender of an echo reply to support the
co
py pad TLV to echo reply.
reply mode {ipv
4 |
router-alert}
(Optional) Specifies the reply mode for the echo request packet.
ipv4—R
eply with an IPv4 UDP packet (default).
router-alert—R
eply with an IPv4 UDP packet with router alert.
interval ms (Optional) Specifies the time, in milliseconds (ms), between successive
M
PLS 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 ex
p-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.
