| IP Commands
– 220 –
◆ To connect to a larger network with multiple subnets, you must
configure a global unicast address. This address can be manually
configured with this command, or it can be automatically configured
using the ip ipv6 autoconfig command (page 218).
◆ When configuring a link-local address, the prefix length is fixed at 64
bits, and the host portion of the default address is based on the
modified EUI-64 (Extended Universal Identifier) form of the interface
identifier (i.e., the physical MAC address). You can manually configure a
link-local address by entering the full address with the network prefix
FE80.
◆ An IPv6 default gateway must be defined if the management station is
located in a different IPv6 segment. An IPv6 default gateway can only
be successfully set when a network interface that directly connects to
the gateway has been configured on the switch.
EXAMPLE
This example specifies the IPv6 address, the prefix length, the IPv6
gateway, and the VLAN to which the address is assigned.

ip ipv6 ping6 This command sends ICMP echo request packets to another node on the
network.
SYNTAX
ip ipv6 ping6 ipv6-addr [packet-size]
ipv6-addr - IP address of the host. An IPv6 address must be
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.
packet-size - The payload size of the ICMP packet. (Range: 8-1400
bytes) The actual packet size excludes MAC, IP and ICMP headers.
DEFAULT SETTING
Packet Size: 68 bytes
Count: 5
