ping
Syntax ping {ip-address | ipv6-address | dns-name} [rapid | detail] [ttl time-to-live] [tos type-of-
service] [size bytes] [pattern pattern] [source ip-address] [interval seconds] [{next-hop ip-
address} | {interface interface-name} | bypass-routing] [count requests] [do-not-
fragment] [router [router-instance] [timeout timeout]
Context <GLOBAL>
Description This command is the TCP/IP utility to verify IP reachability.
Parameters ip-address | dns-name — The remote host to ping. The IP address or the DNS name (if DNS name
resolution is configured) can be specified.
ipv6-address — The IPv6 IP address.
Values x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x: 0 — FFFF H
d: 0 — 255 D
rapid | detail — The rapid parameter specifies to send ping requests rapidly. The results are reported
in a single message, not in individual messages for each ping request. By default, five ping
requests are sent before the results are reported. To change the number of requests, include the
count option.
The detail parameter includes in the output the interface on which the ping reply was received.
Example output:
A:ALA-1# ping 192.168.xx.xx4 detail
