IPv6 Interface
– 1044 –
COMMAND USAGE
â—† The maximum value set by this command cannot exceed the MTU of
the physical interface, which is currently fixed at 1500 bytes.
â—† 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.
â—† All devices on the same physical medium must use the same MTU in
order to operate correctly.
â—† 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
Console(config-if)#ipv6 mtu 1280
Console(config-if)#
