interface. If you do not configure a bandwidth for the logical interface, it is
automatically set to the bandwidth configured for the physical interface.

■ Support for line-rate mode on 10-port 10-Gigabit Oversubscribed Ethernet
(OSE) PIC (T640, T1600, TX Matrix Plus platforms)— Enables you to configure
the T640, T1600, and TX Matrix Plus routers to operate the 10-port 10-Gigabit
OSE PIC in line-rate mode, in which the OSE PIC disables oversubscription and
operates in line-rate mode. By default, the 10-port 10-Gigabit OSE PIC operates
in 2:1 oversubscription mode.

■
New CoS information field added to the show interfaces extensive command
output—The output of the show interfaces extensive command now displays the
class-of-service queue allocation information of the physical interfaces (intelligent
queueing PICs such as IQ2 and so on) under the new class-of-service information
category. In the previous releases, the class-of-service queue allocation
information for physical interfaces was listed within the Packet Forwarding Engine
configuration category:

[Interfaces Command Reference]
■ Restriction on compatibility-mode adtran and verilink—On 2-port and 4-port
channelized DS3 (T3) IQ interfaces, you cannot configure compatibility-mode
adtran, or verilink at the [edit interfaces interface-name t3-options] hierarchy level.
If configured, the default mode is applied on both the interfaces, that is, no
subrating.
[Network Interfaces]
■ Support for internal clocking mode on OSE PICs—The 10-port 10-Gigabit
Oversubscribed Ethernet (OSE) PIC supports only internal clocking mode on its
ports.
