Syntax
ping [vrf {management | vrf-name}] [-4] [-aAbBdDfhLnOqrRUvV] [-c count] [-i
interval] [-I interface] [-m mark] [-M pmtudisc_option] [-l preload] [-p
pattern] [-Q tos] [-s packetsize] [-S sndbuf] [-t ttl] [-T
timestamp_option] [-w deadline] [-W timeout] [hop1 ...] destination
Parameters
● vrf management — (Optional) Pings an IPv4 address in the management virtual routing and
forwarding (VRF) instance.
● vrf vrf-name — (Optional) Ping an IP address in a specified VRF instance.
● -4 — (Optional) Uses the IPv4 route over the IPv6 route when both IPv4 as well as IPv6 default
routes are configured, you must use the following option in the ping command: -4. For example,
OS10# ping vrf management -4 dell.com.
● -a — (Optional) Audible ping.
● -A — (Optional) Adaptive ping. An inter-packet interval adapts to the round-trip time so that one (or
more, if you set the preload option) unanswered probe is present in the network. The minimum interval
is 200 msec for a non-super user, which corresponds to Flood mode on a network with a low round-
trip time.
● -b — (Optional) Pings a broadcast address.
● -B — (Optional) Does not allow ping to change the source address of probes. The source address is
bound to the address used when the ping starts.
● -c count — (Optional) Stops the ping after sending the specified number of ECHO_REQUEST
packets until the timeout expires.
● -d — (Optional) Sets the SO_DEBUG option on the socket being used.
● -D — (Optional) Prints the timestamp before each line.
● -h — (Optional) Displays help for this command.
● -i interval — (Optional) Enter the interval in seconds to wait between sending each packet, the
default is 1 second.
● -I interface-name or interface-ip-address — (Optional) Enter the source interface
name without spaces or the interface IP address:
○ For a physical Ethernet interface, enter ethernetnode/slot/port; for example,
ethernet1/1/1.
○ For a VLAN interface, enter vlanvlan-id; for example, vlan10.
○ For a Loopback interface, enter loopbackid; for example, loopback1.
○ For a port-channel interface, enter port-channelchannel-id; for example, port-channel.
● -l preload — (Optional) Enter the number of packets that ping sends before waiting for a reply.
Only a super user may preload more than three.
● -L — (Optional) Suppress the Loopback of multicast packets for a multicast target address.
● -m mark — (Optional) Tags the packets sent to ping a remote device. Use this option with policy
routing.
● -M pmtudisc_option — (Optional) Enter the path MTU (PMTU) discovery strategy:
84
