This command sets the size of the maximum transmission unit (MTU) for IPv6
packets sent on an interface. Use the no form to restore the default setting.
Syntax
ipv6 mtu size
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:
