Special Cases SONET/SDH Path — When network mode is selected, the appropriate control protocols are
activated when the need arises. For example, configuring an IP interface on the SONET path activates
IPCP while the removal of the IP interface causes the IPCP to be removed. The same applies for
MPLS, MPLSCP, and OSICP.When configuring a SONET/SDH port, the mode command must be
entered in the channel context or an error message is generated.
Default
network — Configures the Ethernet port, TDM channel or SONET path for transport network use.
access — Default channel/port mode for channelized, ASAP, and ATM MDAs.
Parameters network — Configures the Ethernet port, TDM channel or SONET path as service access.
access — Configures the Ethernet port, TDM channel or SONET path for transport network use.
hybrid — Configures the Ethernet port for hybrid use.

Description
This command assigns a specific MAC address to an Ethernet port, Link Aggregation Group (LAG),
Ethernet tunnel, or BCP-enabled port or sub-port.
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

Syntax mtu mtu-bytes

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.
