Release 11.0.2
When 16,000 PPPoA interfaces are configured on an OCx/STMx ATM line
module paired with an OC3-4 I/O module in an ERX14xx model, ERX7xx
model, or ERX310 router, Ping traffic passing through the line module on the
restarting router experiences an outage of 103 seconds, which is beyond the
maximum limit, after a unified ISSU from JunosE Release 9.2.0p1-0 to
9.3.0b0-12. This outage does not occur when the same configuration is applied
on a Gigabit Ethernet interface. [Defect ID 179794]
When a mirror rule that triggers on username is employed for packet mirroring
of dynamic IP subscribers over ATM, removal of the rule does not disable
packet mirroring. [Defect ID 175356]
Work-around:
Use a mirror rule that triggers on account session ID rather than
on username.
When you issue the
no atm atm1483 auto-configure
upperInterfaceType
lockout-time
command in Profile Configuration mode, the lockout time range
does not revert to the default values. [Defect ID 66544]
When one or more ATM1483 attributes appears in a profile, the
show
configuration include-defaults
command fails to display the default values for
all possible ATM1483 attributes. [Defect ID 67157]
The output of the
show atm arp
command displays only 4096 entries when
the line module is configured with more than 4096 NBMA ARP entries. [Defect
ID 68849]
The
baseline interface atm
command fails for a VCD assigned by the router to
F4 OAM circuits. [Defect ID 174482]
Unified ISSU is not supported when ILMI is configured on ATM interfaces.
[Defect ID 176007/177122]
ATM line modules reset after unified ISSU completes at the LAC when an
MLPPP bundle with three links are tunneled to the LNS. [Defect ID 178821]
For PPPoE, the AAL5 inPacket Discards counter might increment erroneously
during call setup when a packet is passed directly to PPPoE for negotiation
rather than being discarded. [Defect ID 51757]
Work-around:
Incremental InPacketDiscards during call setup do not
necessarily indicate a problem. However, we recommend you investigate an
excessive count because that might indicate a connection that cannot be
successfully brought up for some reason, such as RADIUS denials or improper
configuration.
The inPacketOctetDiscards counter in the output of the
show atm vc atm
interface
vcd
command includes both inBytesDropped and
inBytesUnknownProtocol statistics. The inBytesUnknownProtocol statistics
should be displayed by a separate counter.
At the major interface level, the inPacketDiscards counter includes both
inPacketsDropped and inPacketUnknownProtocol statistics. The
inPacketUnknownProtocol statistics should be displayed by a separate counter.
