IPv6 Interface
– 565 –
ping6
This command sends (IPv6) ICMP echo request packets to another node on the
network.
Syntax
ping6 { ipv6-address | host-name } [ count count ] [ size size ]
ipv6-address - The IPv6 address of a neighbor device. You can specify either
a link-local or global unicast address formatted according to RFC 2373 “IPv6
Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal
values. One double colon may be used in the address to indicate the
appropriate number of zeros required to fill the undefined fields.
host-name - A host name string which can be resolved into an IPv6 address
through a domain name server.
count - Number of packets to send. (Range: 1-16)
size - Number of bytes in a packet. (Range: 48-18024 bytes)
The actual packet size will be eight bytes larger than the size specified
because the router adds header information.
Default Setting
count: 5
size: 100 bytes
Command Mode
Privileged Exec
Command Usage
◆
Use the ping6 command to see if another site on the network can be reached,
or to evaluate delays over the path.
◆
The same link-local address may be used by different interfaces/nodes in
different zones (RFC 4007). Therefore, when specifying a link-local address,
include zone-id information indicating the VLAN identifier after the % delimiter.
For example, FE80::7272%1 identifies VLAN 1 as the interface from which the
ping is sent.
◆
When pinging a host name, be sure the DNS server has been enabled (see
page 524 ). If necessary, local devices can also be specified in the DNS static host
table (see page 526 ).
◆
When using ping6 with a host name, the router first attempts to resolve the
alias into an IPv6 address before trying to resolve it into an IPv4 address.
Example
Console#ping6 FE80::2E0:CFF:FE00:FC%1/64
Type ESC to abort.
PING to FE80::2E0:CFF:FE00:FC%1/64, by 5 32-byte payload ICMP packets,
timeout is 3 seconds
response time: 20 ms [FE80::2E0:CFF:FE00:FC] seq_no: 1
response time: 0 ms [FE80::2E0:CFF:FE00:FC] seq_no: 2
