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.
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.
When you want to use a configuration script to configure IP shared interfaces
that reference a physical interface, you must issue the service show
configuration format 2 command before you generate the script. If the default
show configuration format (format 1) is enabled instead, the generated script
cannot properly configure the IP shared interfaces because they are created
before the physical interfaces. To properly configure the shared interfaces in
this event, run the generated format 1 script twice.
