Card, Adapter Card, and Port Command Reference
mode
Syntax mode {access | network}
no mode
Context config>port>ethernet
Description This command configures an Ethernet port for access or network mode operation.
An access port is used for customer-facing traffic on which services are configured. A Service Access
Point (SAP) can only be configured on an access port or channel.
Once an Ethernet port has been configured for access mode, multiple services can be configured on
the Ethernet port.
A network port participates in the service provider transport or infrastructure network when a
network mode is selected.
The no form of this command restores the default.
Default
network
Parameters access — configures the port as service access
network — configures the port for transport network use
mtu
Syntax mtu mtu-bytes
no mtu
Context config>port>ethernet
Description This command configures the maximum payload MTU size for an Ethernet 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 to be transmitted over a given port that are
larger than the MTU of the port will be fragmented or discarded, depending on whether the DF bit is
set in the packet header.
If the port mode or encapsulation type is changed, the MTU assumes the default values of the new
mode or encapsulation type.
The no form of this command restores the default values.
Default The default MTU value depends on the port type, mode, and encapsulation as listed in the following table.
