8.8  ping 
This command sends (pings) an ICMP echo request messages to a remote destination to 
check connectivity. Pings have an IP and ICMP header, followed by a struct timeval and then 
an arbitrary number of "pad" bytes used to fill out the packet. Ping works with both IPv4 and 
IPv6. 
Syntax 
ping {<IPv4 Address>|ipv6 <IPv6 Address>|<Hostname>} [ethernet 
mpid] [source data {interface|source-address|vrf}] [repeat <Echo 
Requests>] [size <Payload Size>] [summarized] 
 
Command  Description 
<IPv4 Address>  Configures the IPv4 IP address in dotted-decimal notation 
(X.X.X.X) or as a hostname. 
ipv6 <IPv6 Address>  Configures an IPv6 address as X:X::X:X or as a hostname. 
<Hostname>  Configures a hostname or FQDN (.g., abc.com).

Management (CFM) per IEEE 802.1ag. This is a loopback

(Optional) Configures the number (1-300) of echo requests. 
(Optional) Configures the payload size (0-max packet size).
