How can I ping with source option in Cisco Router?
I have a ISR 4321 Router, I want to ping from a source IP address:
Router#ping ?
WORD Ping destination address or hostname
ip IP echo
ipv6 IPv6 echo
<cr>
there I have two question, how can I add source options in Cisco Router?
I tried use the
ping 10.0.0.1 source x
ping 10.0.0.1 -s x
all do not work.
and when I #ping ?, what's the meaning of <cr>?
rtr3745#ping ?
WORD Ping destination address or hostname
clns CLNS echo
ip IP echo
ipv6 IPv6 echo
mpls MPLS echo
srb srb echo
tag Tag encapsulated IP echo
<cr>
rtr3745#ping ip ?
WORD Ping destination address or hostname
<cr>
rtr3745#ping ip 1.1.1.1 ?
data specify data pattern
df-bit enable do not fragment bit in IP header
repeat specify repeat count
size specify datagram size
source specify source address or name
timeout specify timeout interval
validate validate reply data
<cr>
"?" shows the next valid element. Source can be the address of an interface, or the name of that interface.
You can use the ping command for choosing Extended commands options:
Router#ping
Protocol [ip]:
Target IP address: 10.0.12.1
Repeat count [5]: 10
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: 1.1.1.1
...
the <cr> it stands for "Carriage Return."
it means that, you can just click enter and the command is complete. There may be more commands in the ? output that you can append, but the <cr> means that you can hit enter, end the command, and not get an error for entering an incomplete command.
