Command Mode
Global Configuration
Command Usage
◆ All IPv6 addresses must be 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.
◆ 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.
◆ An IPv6 default gateway must be defined if the destination has been assigned
an IPv6 address and is located in a different IP 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.
