General Port Commands
The no form of this command restores the default.
Default
access — Configures the Ethernet port for transport access use.
Parameters
access — Configures the Ethernet port as service access.
access uplink — Configures the Ethernet port for transport access uplink use.
mac
Syntax mac ieee-address
no mac
Context config>port>ethernet
config>lag
config>eth-tunnel
Description
This command assigns a specific MAC address to an Ethernet port, Link Aggregation Group (LAG),
Ethernet tunnel.
Only one MAC address can be assigned to a port. When multiple mac commands are entered, the last
command overwrites the previous command. When the command is issued while the port is
operational, IP will issue an ARP, if appropriate, and BPDU's are sent with the new MAC address.
The no form of this command returns the MAC address to the default value.
Default A default MAC address is assigned by the system from the chassis MAC address pool.
Parameters
ieee-address — Specifies the 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff
mtu
Syntax mtu mtu-bytes
no mtu
Context config>port>ethernet
Description
This command configures the maximum payload MTU size for an Ethernet port port. The Ethernet
port level MTU parameter indirectly defines the largest physical packet the port can transmit or the
far-end Ethernet port can receive. Packets received larger than the MTU will be discarded. Packets
that cannot be fragmented at egress and exceed the MTU are discarded.
The value specified for the MTU includes the destination MAC address, source MAC address, the
Ethertype or Length field and the complete Ethernet payload. The MTU value does not include the
preamble, start of frame delimiter or the trailing CRC.
The no form of this command restores the default values.
Default
The default MTU value depends on the (sub-)port type, mode and encapsulation and are listed in the
following table:

where aa, bb, cc, dd, ee and ff are hexadecimal numbers. Allowed values are any non-broadcast,
non-multicast MAC and non-IEEE reserved MAC addresses.
