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
â—† Use the ping6 command to see if another site on the network can be
reached, or to evaluate delays over the path.
â—† 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.
â—† 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).
â—† 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.
