General Port Commands
multiple services can be configured on the Ethernet port, a TDM channel or SONET path. Note that ATM,
Frame Relay, and cHDLC port parameters can only be configured in the access mode.
A network port or channel participates in the service provider transport or infrastructure network when a
network mode is selected. When the network option is configured, the encap-type cannot be configured for
the port/channel.
When network mode is selected on a SONET/SDH path, 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.
The no form of this command restores the default.
SONET/SDH Path — When network mode is selected, the appropriate control protocols are activated

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.

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.
