ipv6 mtu

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

The maximum value set by this command cannot exceed the MTU of the physical interface,
which is currently fixed at 1500 bytes.

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:

Console(config)#interface vlan 1
