Known Behavior
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 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.
When you shut down the only outgoing IP interface to the IP destinations of
GRE/IP tunnels, the tunnels remain in the up state rather than transitioning to
down. As a consequence, all IP routes that use these tunnels as next hops also
remain in the routing table.
Do not include a not protocol clause in any classifier control list for policies
attached to an interface on an ES2 10G Uplink LM. The not protocol
functionality is not available for this module.
