JUNOSe 10.2.2 Release Notes
22
Known Behavior
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.
If you have enabled ipInterface logging at a priority of debug, the
acknowledgment that an interface has been deleted from the line modules can
return to the SRP module after the layers beneath IP have deleted their
interfaces. Consequently, the original name of the interface cannot be resolved
or displayed in the log, and the system instead displays the ifIndex of the IP
interface. This behavior has no functional effect other than that the log is
misleading. However, previous log events indicate that the interface deletion
was beginning.
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.
