IPv6 Interface
– 1415 –
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 1366). If necessary, local devices can also be specified in the
DNS static host table (see page 1368).
◆ When using ping6 with a host name, the switch first attempts to
resolve the alias into an IPv6 address before trying to resolve it into an
IPv4 address.
