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
624). If necessary, local devices can also be specified in the DNS static host
table (see
page
626).
◆
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.
