Known Behavior
Copyright © 2010, Juniper Networks, Inc.
z
There is a very small chance that some line modules can have an improperly
modified keying block that prevents the module from proper seating in the top slot of
an older ERX7xx chassis or a preproduction ERX310 chassis. For example, this
problem has been observed for an OCx/STMx module in slot 2 of an early-test
ERX310 chassis.
Work-around
: Remove the keying block to insert the module into the top slot, or
insert the module into a different slot.
HDLC
z
By design, on the cOC12/STM4 module you cannot delete a serial interface while
data for the interface is still enqueued. The enqueued data can drain only when the
interface is operationally up. Therefore you must ensure that the interface is
operationally up before you delete it. For example, if you have issued the
shutdown
command for the interface before you try to delete the interface, issue the
no
shutdown
command, then delete the interface.
IP
z
IP interface statistics become inconsistent when a slot is reset, because some traffic
(such as control traffic) might be destined for the SRP module and is therefore
counted elsewhere.
z
When you upgrade from certain releases to JunosE Release 9.2.0p1-0 or
higher-numbered releases, descriptions configured for IP interfaces or IP
subinterfaces are not retained across the upgrade when the descriptions are shorter
than 9 characters in length. Additionally, VRF descriptions are not retained across the
upgrade when the combined length of the VRF description and the VRF name is
shorter than 9 characters. This behavior is seen during upgrades using a reload,
stateful SRP switchover, or unified ISSU. Upgrades from the following releases are
affected by this behavior:
−
7.x.x
−
8.0.x
−
8.1.x, 8.2.x, and 9.x.x builds created before July 23, 2008
Examples of descriptions that are not retained across the upgrade:
