Known Behavior
23
Release 11.0.1
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
host1(config)#
ip vrf 123
host1(config-vrf)#
description longdescription
Work-around:
Before you upgrade from an affected release to JUNOSe Release
9.2.0p1-0 or higher-numbered releases, ensure that you do the following:
Change IP interface and subinterface descriptions to 9 or more characters.
Change VRF descriptions, VRF names, or both so that the combination of
associated VRF names and descriptions consists of 9 or more characters.
The
ip tcp adjust-mss
command, which modifies the maximum segment size
for TCP SYN packets traveling through the interface, is not supported on the
ES2 10G LM or ES2 10G Uplink LM.
