MultiPort/LT	Software Release Notes

Software Release Notes	23rd August 1997

These Software Release Notes apply to MultiPort/LT Wanda 
Versions 2.10 and 2.09.


1.	MultiPort/LT Code V2.10

1.1.  Enhancements in MultiPort/LT Code V2.10

Improvements have been made in scheduler context switching,
which results in speed improvements to all MultiPort/LT
operations.

1.2.  Bugs Fixed in MultiPort/LT Code V2.10

A problem was introduced with Wanda V2.09 which affected
users of the MultiPort/LT NBP filtering feature.  Whenever
any form of filtering was being enabled, further unintended
device hiding would occur.  This problem has been fixed with
Wanda V2.10.


2.  MultiPort/LT Code V2.09

2.1.	Enhancements in MultiPort/LT Code V2.09

The following enhancement is present in MultiPort/LT Code V2.09.

o	Apple Remote Access Modem DIscrimination
 
The MultiPort/LT code has always automatically detected ARA V1
and ARA V2 clients. This has caused one reported problem where
an ARA V2 client was using a modem that couldn't be configured
by the client's ARA CCL script to disable the MNP protocol in
the modem.  This was a PCMCIA data card connected to a cellular
mobile phone using a modem-pool in the exchange.

The MultiPort/LT code is now able to discriminate between an 
ARA V1 client and a modem attempting MNP V1, and behaves in 
such a manner that the connection now succeeds.


2.2.	Bugs Fixed in MultiPort/LT Code V2.09

The following bugs have been fixed in MultiPort/LT Code V2.09.

o	CCL Parser Improved

The CCL Parser could fail under certain unusual combinations 
of quotes and strings.

o	Guest Login Log Message

If Guest Login was disabled and a Guest Login was attempted, 
the Log message printed random data in the place where the 
"Username" should have been.

o	Password Expiry

If Password Expiry is enabled, but a user is disallowed from 
changing their password, they could still access their account 
after the password had expired.

o	RIP Broadcast

If the RIP (IP Router Information Protocol) is enabled, but 
there were no other RIP-broadcasting routers on the Ethernet, 
then the MP/LT would stop broadcasting RIP packets after a 
short period.  If the MP/LT was the only IP Router on the 
network, then other hosts relying on these broadcasts to route 
packets to and through the MP/LT would fail.  The MP/LT now 
broadcasts RIP packets irrespective of the existence of other 
routers.  There is a flag available to reinstate the old 
behavior if required.

o	MTU Path Discovery

The MP/LT didn't return an ICMP packet if a packet required 
fragmentation and the "Don't Frag" bit was set. This prevented 
hosts from using MTU Path Discovery through the MP/LT.  The 
MP/LT now implements MTU Path Discovery support as per the 
RFC, including returning the MTU in the ICMP packet.

o	Clock Accuracy

The MP/LT's internal clock was losing 1' 24" per day.

o	Larger Config FLASH

The MP/LT now supports the use of a 256 kbyte configuration 
FLASH chip (28F020).  This may be required if the current 32 
kbyte limit is exceeded by large CCL scripts or user lists.  
Contact WCC before changing the chip though.

o	ARP Table Report to MultiPort Manager

If there were MacIP-based entries in the ARP cache, then the 
Ethernet ARP entries weren't returned to the MultiPort Manager 
ARP display.  MacIP-based ARP entries aren't returned to 
MultiPort Manager at all now.

o	ARP Reports

The MultiPort/LT now logs ARP Broadcasts, martians and other 
incoming packets using the MP/LTs IP address.

o	Smaller Code Size

The size of the Wanda code has been reduced.  This increases 
the amount of memory available for other purposes, and makes 
it easier to download new versions of the code.

o	Speed Improvements

Some parts of the code have been made more efficient.
