Known Behavior
21
Release 10.3.1
When you configure 1:5 line module redundancy by using either the 4XOC3
APS MULTIMODE or 4XOC3 APS SINGLE MODE I/O module, the spare R-Mid
OCX I/O module you install must have assembly number 350-00094-01 Rev.
A01 or later. Spare R-Mid OCX I/O modules with an earlier assembly number
are not supported for 1:5 redundancy configurations that use either the 4XOC3
APS MULTIMODE or 4XOC3 APS SINGLE MODE I/O module.
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
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
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:
host1(config-if)#
ip description 12345678
host1(config)#
ip vrf 123
host1(config-vrf)#
description 45678
Examples of descriptions that are retained across the upgrade:
host1(config-if)#
ip description longdescription
host1(config)#
ip vrf longername
host1(config-vrf)#
description 45678
