Known Behavior

Release 11.0.2
To bridge unicast known-DA packets at line rate on both 2-Gbps ports of the
GE-2 line module or the GE-HDE module when paired with the GE-2 SFP I/O
module, the minimum packet size must be at least 144 bytes.
When installed in the ERX1440 router, the GE-2 module delivers full bandwidth
of 4 GB per line module (2 GB at the ingress and 2 GB at the egress) only when
installed in slot 2 or slot 4, and when the SRP-40G+ module is used in the
router. When installed in any other ERX1440 slot, the GE-2 module delivers a
maximum bandwidth of 2 GB per line module (1 GB maximum at the ingress
and 1 GB maximum at the egress). Therefore, of the maximum 24 possible
ports for the module in an ERX1440 chassis (that is, two ports in each of 12
slots), full bandwidth is delivered only on a maximum of four ports (those in
slots 2 and 4).
When installed in the ERX1440 router, the GE-HDE line module delivers full
bandwidth of 4 GB per line module (2 GB at the ingress and 2 GB at the egress)
only when installed in slot 2 or slot 4, and when the SRP-40G+ module is used
in the router. When installed in any other ERX1440 slot, the GE-HDE module
delivers a maximum bandwidth of 2 GB per line module (1 GB maximum at the
ingress and 1 GB maximum at the egress). Therefore, of the maximum 96
possible ports for the module in an ERX1440 chassis (that is, 8 ports in each of
12 slots), full bandwidth is delivered only on a maximum of 16 ports (those in
slots 2 and 4).
When the GE-2 line module or the GE-HDE line module is installed in either the
ERX1440 router or the ERX310 router and both ports are active, line rate
performance is achieved only with packets that are 174 bytes or larger. The
line module might not achieve line rate with packets that are smaller than
174 bytes.
Support for the 0x9200 S-VLAN Ethertype has been removed. You can no
longer specify the
9200
option with the
svlan ethertype
command.
When you upgrade to Release 7.1.0 or higher-numbered release, the software
automatically transfers existing configurations that use the 0x9200 Ethertype
to the 0x88a8 Ethertype.
The
show interface gigabitEthernet
command output does not display the
following line of output for Gigabit Ethernet modules that do not support SFPs,
such as the GE Single Mode I/O module and GE I/O Multi Mode I/O modules:
Primary/Secondary link signal detected
Primary/Secondary link signal not detected
Flash
Flash cards manufactured by Wintec are present on some currently deployed
routers. When you upgrade the JunosE Software on such routers, the firmware
on the flash card controller is automatically updated during diagnostics. During
this reboot, the software runs an integrity check on the file system to verify that
the firmware update did not corrupt the contents of the flash card. This
integrity check is an expected side effect of the enhanced firmware available in
this release. The integrity check does not indicate a problem with the flash card
or its contents.
