Default Command Mode Usage Information Example ○ dont does not set the Don't Fragment (DF) flag. ● -p pattern - (Optional) Enter a maximum of 16 pad bytes to fill out the packet you send to diagnose data-related problems in the network; for example, -p ff fills the sent packet with all 1's. ● -Q tos - (Optional) Enter a maximum of 1500 bytes in decimal or hex datagrams to set the quality of service (QoS)-related bits. ● -s packetsize - (Optional) Enter the number of data bytes to send, from 1 to 65468, default 56. ● -S sndbuf - (Optional) Set the sndbuf socket. By default, the sndbuf socket buffers one packet maximum. ● -t ttl - (Optional) Enter the IPv6 time-to-live (TTL) value in seconds. ● -T timestamp option - (Optional) Set special IP timestamp options. Valid values for timestamp option - tsonly (only timestamps), tsandaddr (timestamps and addresses), or tsprespec host1 [host2 [host3 [host4]]] (timestamp pre-specified hops). ● -v - (Optional) Verbose output. ● -V - (Optional) Display the version and exit. ● -w deadline - (Optional) Enter the time-out value in seconds before the ping exits regardless of how many packets are sent or received. ● -W timeout - (Optional) Enter the time to wait for a response in seconds. This setting affects the time-out only if there is no response, otherwise ping waits for two round-trip times (RTTs). ● hop1 ... (Optional) Enter the IPv6 addresses of the pre-specified hops for the ping packet to take. ● destination - Enter the IPv6 destination address in A:B::C:D format, where you are testing connectivity. Not configured EXEC This command uses an ICMP ECHO_REQUEST datagram to receive an ICMP ECHO_RESPONSE from a network host or gateway. Each ping packet has an IPv6 and ICMP header, then a time value and a number of ''pad'' bytes used to fill out the packet. A pingv6 operation sends a packet to a specified IPv6 address and then measures the time it takes to get a response from the address or device. When you use the -I option and enter an IP address, OS10 considers it as the source address. If you use an interface name instead of the IP address, OS10 considers it as the egress interface. With the -I option, if you ping a reachable IP address using the IP address of a loopback interface as the source interface, the ping succeeds. However, if you ping a reachable IP address using the name of the loopback interface as the source interface, the ping fails. This is because the system considers the loopback interface as the egress interface.
