Ethernet Interface Management Window
Layer 2
The Layer 2 area provides the following information:
•
MAC Address—Displays the MAC address of the interface. This attribute is read-only.
•
MTU—Displays the maximum transmission unit (MTU) size in bytes. The size of the largest packet
which can be sent/received on the interface, specified in octets. For interfaces that are used for
transmitting network datagrams, this is the size of the largest network datagram that can be sent on
the interface.
Note
IOS 12.1(8a)E5 caveat: Jumbo frame support is incompatible with the IS-IS routing protocol.
Leave the MTU size at the default value on any interface where IS-IS provides routing.
Note
For Native IOS, any value for the MTU will be accepted although it is recommended that only
1500 or 9600 bytes is configured. For Hybrid OS, if jumbo frames are enabled, the MTU will be
reported as 9216 bytes. If jumbo frames are not enabled, the MTU will be reported as 1500 bytes.
Any input value greater than or equal to 9216 bytes will be taken as 9216 bytes, and the jumbo
frames will be enabled. Any input value less than 9216 bytes will be taken as 1500 bytes, and
the jumbo frames will be disabled.
•
Default VLAN—Displays the VLAN to which this interface belongs if it stops trunking. This is a
read-only attribute.
•
Advanced Features—Launches the Ethernet Advanced Configuration window.
