DELL CONFIDENTIAL – PRELIMINARY 5/15/12 – FOR PROOF ONLY
• no ipv6 neighbor ipv6_addr { ethernet interface-number | vlan vlan-id | port-channel number }
–
ipv6_addr — IPv6 address to map to the specified MAC address.
–
hw_addr — MAC address to map to the specified IPv6 address.
–
ethernet interface-number — Valid port number.
–
vlan vlan-id — VLAN number.
–
port-channel number — Port channel number.
Default Configuration
This command has no default setting.
Command Mode
Global Configuration mode.
User Guidelines
•The ipv6 neighbor command is similar to the arp (global) command.
• If an entry for the specified IPv6 address already exists in the neighbor discovery cache, learned through
the IPv6 neighbor discovery process, the entry is automatically converted to a static entry.
•Use the
show ipv6 neighbors command to view static entries in the IPv6 neighbor discovery cache.
Example
The following example configures a static entry in the IPv6 neighbor discovery cache.
ipv6 set mtu
The ipv6 mtu Privileged EXEC mode command sets the Maximum Transmission Unit (MTU) size of IPv6
packets sent on an interface. Use the default parameter to restore the default MTU size.
Syntax
• ipv6 set mtu { ethernet interface | vlan vlan-id | port-channel port-channel-number } { bytes | default }
•
ethernet interface — Valid interface number.
•
vlan vlan-id — VLAN number.
•
port-channel port-channel-number — Valid Port Channel index.
•
bytes — MTU in bytes with a minimum is 1280 bytes.
•
default — Sets the default MTU size to 1500 bytes.
