• The timeout milliseconds parameter specifies how many milliseconds the router waits for a reply
from the pinged device. You can specify a timeout from 1 - 4294967296 milliseconds. The default is
5000 (5 seconds).
• The ttl number parameter specifies the maximum number of hops. You can specify a TTL from 1 -
255. The default is 64.
• The size bytes parameter specifies the size of the ICMP data portion of the packet. This is the
payload and does not include the header. You can specify from 0 - 10000. The default is 16.
• The no-fragment keyword turns on the "do not fragment" bit in the IPv6 header of the ping packet.
This option is disabled by default.
• The quiet keyword hides informational messages such as a summary of the ping parameters sent
to the device, and instead only displays messages indicating the success or failure of the ping. This
option is disabled by default.
• The verify keyword verifies that the data in the echo packet (the reply packet) is the same as the
data in the echo request (the ping). By default the device does not verify the data.
• The data 1 - 4 byte hex parameter lets you specify a specific data pattern for the payload instead of
the default data pattern, "abcd", in the packet's data payload. The pattern repeats itself throughout
the ICMP message (payload) portion of the packet.
NOTE
For parameters that require a numeric value, the CLI does not check that the value you enter is within
the allowed range. Instead, if you do exceed the range for a numeric value, the software rounds the
value to the nearest valid value.
• The brief keyword causes ping test characters to be displayed. The following ping test characters
are supported.
! Indicates that a reply was received.
. Indicates that the network server timed out while waiting for a reply.
U Indicates that a destination unreachable error PDU was received.
I Indicates that the user interrupted ping.
Configuring an IPv6 Syslog server
To enable IPv6 logging, specify an IPv6 Syslog server. Enter a command such as the following.
device(config)#log host ipv6 2000:2383:e0bb::4/128
Syntax: log host ipv6 ipv6-address [ udp-port-num ]
The ipv6-address must be in hexadecimal using 16-bit values between colons as documented in RFC
2373.
The udp-port-num optional parameter specifies the UDP application port used for the Syslog facility.
Viewing IPv6 SNMP server addresses
Some of the show commands display IPv6 addresses for IPv6 SNMP servers. The following shows an
example output for the show snmp server command.
device#show snmp server
