JUNOSe 10.3.1 Release Notes

Known Behavior
Subscriber Interfaces
MAC address validation is not supported on either of the following:
Packet-triggered subscriber interfaces that are created dynamically
Packet-triggered subscriber interfaces that are managed on the primary IP
interface
A packet-triggered subscriber interface is created when the router receives a
packet with an IP source address that does not match any entries in the
demultiplexer table. When the router detects an unmatched packet, it
generates a trigger event that determines whether to create a dynamic
subscriber interface or configure an existing interface. To configure packet
detection on the router, use the
ip auto-detect ip-subscriber
command.
System
ERX routers display different behavior from E120 routers and E320 routers
when reporting modules as inactive.
ERX routers report a module as inactive when either:
The I/O module is not present
The primary line module is fully booted and ready to resume operation. In
this case, the standby is currently providing services.
E120 routers and E320 routers report a module as inactive when either:
The primary line module has no IOAs.
The primary line module has IOAs, but they have failed diagnostics.
The standby line module has taken over for the primary line module, and
has control of the IOAs.
Because E120 and E320 routers can accommodate up to two IOAs per slot, at
least one IOA must be online. If the second IOA fails, the line module is still
online, but does not use both IOAs. You can ensure that every module is up
and active in the system and not in a failed state by issuing the
show version
all
command.
In a router with a redundancy group that does not span quadrants (for
example, a three-slot redundancy group that spans slots 0, 1, and 2 in an
ERX1410 chassis), the potential bandwidth of the redundant module is
erroneously included in the quadrant bandwidth calculation. The
show
utilization
command might indicate that the bandwidth is exceeded for
modules in that group. [Defect ID 31034]
When you copy the running configuration to NVS, the E Series router verifies
whether it has available space equal to at least twice the size of the .cnf file. If
the space is insufficient, you cannot complete the copy. [Defect ID 40655]
Work-around:
Make sufficient space on the NVS by deleting .rel or .cnf files.
