packets sent on an interface. Use the no form to restore the default setting.
Syntax

no ipv6 mtu
size - Specifies the MTU size. (Range: 1280-65535 bytes)
Default Setting
1500 bytes
Command Mode
Interface Configuration (VLAN)
Command Usage
• IPv6 routers do not fragment IPv6 packets forwarded from other routers.
However, traffic originating from an end-station connected to an IPv6 router
may be fragmented.
• All devices on the same physical medium must use the same MTU in order to
operate correctly.
• IPv6 must be enabled on an interface before the MTU can be set.
Example
The following example sets the MTU for VLAN 1 to 1280 bytes:
