Known Problems and Limitations
This section describes known problems and limitations in Cisco IOS for
S/390 Version 1.0.


Multicast is not supported within the Cisco IOS for S/390 Fault Tolerant
feature.


Files to be accessed by OpenEdition must reside within the hierarchical
file system (HFS). To move files from a remote system to the HFS requires
two steps. Two JCL streams, OPUT and OGET, are provided in the CNTL
library as examples of how this can be accomplished using MVS batch jobs.


Users with socket applications that use non-blocking I/O and check for
either EWOULDBLOCK or EAGAIN errno values should consider modifying their
applications to check for both.

Cisco IOS for S/390 returns EWOULDBLOCK to provide compatibility with IBM
TCP/IP for MVS. Some non-MVS socket implementations may return EAGAIN as
specified in POSIX documents. Check for both to ensure maximum
portability.


The MAXSTGPCT parameter of IFSPARM in member IJTCFG00 controls TCP
connections only. This parameter does not currently support UDP and RAW
protocol connections.


During installation of the Cisco IOS for S/390 Version 1.0 base product on
systems using IBM's Binder at DFSMS level 1.3.0, the following error may
occur:

IEW2292E B403 OPTION VALUE MISSING OR INVALID FOR OPTION name

To avoid this error, apply IBM PTF UW26269 prior to installation.
