Ping and Traceroute Commands
The ping (Packet Internet Groper) command is a common method of troubleshooting the accessibility of devices. It sends a
series of Internet Control Message Protocol (ICMP) echo-request packets to determine if a remote host is active or
inactive.
ping ipv6 <ipv6 address> [mgmt] [output-interface {cable | tengigabitethernet | gigabitEthernet}
<slot>/<port>] [payload <payload pattern>] [repeat-count <int>] [size <int>] [source <ip address>]
[timeout <int>] [tos <int>] [ttl <int>] [validate]
Note: Use
ping ipv6
if it is a link-local interface, and then specify the output-interface option. This option is not available
for the standard ping command.
The traceroute command is a troubleshooting tool that helps to determine the path a packet takes to get to a destination.
traceroute ipv6 <ipv6 address> [max-ttl <int>] [mgmt] [source <ipv6 address>] [timeout <sec>]
[probe-count <int>] [min-ttl <int>] [port-number <int>] [tos <int>]
The IPv6 DHCP process differs from that of IPv4. An example of the message:
