Juniper JUNOS 10.1 - RELEASE NOTES REV 4 Release Note page 43

Changes in Default Behavior and Syntax in JUNOS Release 10.1 for M Series, MX Series, and T Series Routers
interface. If you do not configure a bandwidth for the logical interface, it is
automatically set to the bandwidth configured for the physical interface.
[Network Interfaces]
Support for line-rate mode on 10-port 10-Gigabit Oversubscribed Ethernet
(OSE) PIC (T640, T1600, TX Matrix Plus platforms)
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.
[System Basics]
New
output The output of 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

[Interfaces Command Reference]
Restriction on compatibility-mode adtran and verilink On 2-port and 4-port
channelized DS3 (T3) IQ interfaces, you cannot configure
adtran
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.
