Revision Notes for Router Software 9.00 rev 2
=============================================================================
SITE MANAGER COMPATIBILITY
=============================================================================
Router Version is managed by Site Manager version
v9.00 --------------------------------------> v3.00, 3.00 Rev 1
9.00 Rev 2 ---------------------------------> v3.00, 3.00 Rev 1
-----------------------------------------------------------------------------
Revision 9.00/2 corrects the following problem:
=============================================================================
CR 20681: Tools.
In Version 9.00, Revision 1, the VME-based router boot image,
ace.out, contains an executable file that was built with an
incorrect pathname. This causes problems when you attempt to open
and/or save the ace.out image file using the Image Builder in
PC and UNIX-based Site Manager. PC Site Manager will not allow
you to open the ace.out image using the Image Builder; UNIX Site
Manager will allow you to open ace.out in Image Builder but will
save the file with zero bytes.
============================ Revision 9.00/1 ================================
Revision 9.00/1 corrects the following problems:
=============================================================================
CR 18201: Scripts/ATM.
When you enter SHOW ATM, duplicate information displays.
CR 18214: DLSw.
The DLSw Packaging and DLSw Protocol Prioritization
Global parameter needs to be added to the dls.bat file. This
parameter displays when you enter SHOW DLS BASE.
CR 18215: DLSw.
When you enter SHOW DLS LOCAL from the Technician Interface in a
SDLC configuration, the ID number that displays is different
than the Id number shown in the MIB. Also, the Link Station Address
should be converted to hexadecimal.
CR 17415: DVMRP.
SHOW DVMRP needs a value-- ON or OFF-- to indicate the status of
pruning. SHOW DVMRP CIRCUITS needs to include status of "advertise
own interface".
CR 17414: IGMP.
Enhance display of ³SHOW IGMP CIRCUITS DISABLED² script.
CR 14864: Switched Services.
When you enter SHOW PPP CHAP Local, a run error occurs if PPP
is configured on a dial-up circuit.
CR 16478: IP.
A bus error may occur in IP while aging routes if other tasks
are accessing the route entries simultaneously.
CR 17698: IP.
The following misleading IP warning message might be logged
periodically:
³Error deleting x.x.x.x from Aging Queue-- Not Found.²
CR 16838: LNM.
A RESYNC from an LNM station may fail following a nearest upstream
neighbor (NAUN) change of a router's interface to the ring to be
RESYNC'd. The failure reported from the LNM station generally
indicates no response from the router's upstream neighbor.
However, the failure follows that station even if another device
becomes the routers¹ nearest upstream neighbor.
CR 18598: X.25.
Unable to use a large window size with modulo 128. When you
attempt to use the larger window sizes 124-127, the line becomes
congested with RNRs while no traffic is being sent. With window
sizes 123 and sizes less than 123, you get RNRs as the traffic
load increases.
CR 18513: DLSw.
A specific frame exchange between stations connected through a
DLSw cloud can cause an incoming XID to be incorrectly transmitted
as an outgoing TEST response from the same interface. This TEST
response has the P/F bit set to 0, which causes the PC that
receives it to hang. Although the PC should not hang (from the
LLC point of view the frame is correct), the router is considered
responsible for it since there is no reason to send such a frame.
CR 18830: APPN.
When you enter APPN SHOW PORT, the following system message appears:
MIB variable not found
CR 18945: Frame Relay Switch.
If congestion control is activated on a HSSI or SYNC trunk, any
frames that have the bit DE set will be changed to NONDE at egress.
CR 16948: DLSw.
If you have an active NetBIOS session running over a DLS switch and
you disable the TCP base on one of the DLS routers, a bus error
occurs, causing loss of NetBIOS traffic.
CR 18937: IPX.
The next hop network for routes does not remain constant when
redundant equal cost paths between two routers exist and the
number of paths is greater than the maximum paths configured.
As a result, when interfaces are disabled/enabled, some networks
may stop advertising and clients may fail to connect to servers.
CR 18986: VINES.
VINES may fault when aging routes.
CR 18990: IGMP.
Several problems with IGMP scripts have been resolved.
CR 15834: ISDN_DRVR
The munich driver failed to conform to the NET5
specifications, as determined during the PRI ISDN layer 1
pre-testing.
CR 19132: OSPF.
An incorrect argument passed to ospf_submit_route may cause
a bus error during route calculation.
CR 19127: OSPF.
An Area Boundary Router (ABR) does not generate a default into a
stub area unless the "Import Summaries" switch, which determines
whether internal OSPF networks are summarized and flooded into a
stub area, is set to "Yes". An ABR should generate a default
summary into a stub area, regardless of the switch setting
for "Import Summaries".
CR 18279: RIP.
RIP allows a RIP entry to age beyond the maximum allowable timeout
limit in the routing table instead of removing it from the table.
CR 18810: Frame Relay Switch.
Converting from BNX Version 4.20 to BNX Version 5.0 produced errors
when using a customer configuration file.
CR 19301: Frame Relay Switch.
An A-Bit MIB listener parameter is required to dynamically
convert large switching environments to A-Bit switching environment.
wfFrSwDlcmiEntry.wfFrSwDlcmiCrossNet Listen Enable should be
disabled. This causes the management entity on a Frame Relay
circuit to disregard end-to-end updates.
CR 19439: Frame Relay Switch.
A BNX NNI running Annex A to a Cascade switch causes repeated "Bad
Report Type" errors, and eventually shuts down the PVCs on the NNI
after exceeding the error threshold.
CR 18885: DLSw.
When you establish a local NetBIOS session, the DLSw router
creates an LLC2 link entry for that session. As a result, a DISCp
that is sent between the client and server to initiate session
shutdown causes the router to generate a DMf (0x1f) on behalf of
the server.
CR 19450: MCT1E1.
The TI script file hardware.bat does not support the new
MCE1-II Respin link module IDs.
CR 19414: BGP.
When booting a BGP peer, it is possible that after the router
boots, it will receive messages indicating that the BGP port is
unreachable and therefore never establish a peer relationship.
This condition is known to occur in large routing environments.
CR 19095: LB.
A router that has slots with different memory sizes may end up
with different bridge table sizes on different slots. As a
result, packets that should be forwarded instead get flooded,
causing decreased performance.
CR 19543: Source Routing Bridge.
In a Group Mode configuration within Frame Relay, the Hub router
may transmit Specifically Routed Frames (SRFs) out the incorrect
DLCI intermittently. This condition occurs on a Hub router within a
nonfully meshed environment.
CR 19603: IPX.
A watchdog occurred on a FRE1 while attempting to run numerous
(1000) lost router algorithm processes.
CR 18574: Source Routing Bridge.
Under certain conditions, a Frame Relay interface configured for
Transparent Bridge, Source Route Bridge, and IP will interpret an
incoming frame incorrectly as a Source Routed 8101 type frame.
This causes a buffer to be incorrectly formed and passed within
the router, thereby producing a parity violation on the sending
FRE2 or a tag violation on a FRE1. This condition occurs when
receiving a small Ethernet type frames (0x27 bytes) after
processing several Source Routing Bridge (SRB) frames.
CR 19563: Source Routing Bridge.
Upgrading a router to Version 8.11 causes other routers on the
FDDI ring running Version 7.80 to panic on the FDDI slot
configured for Source Routing Bridge. As a result, the router
running Version 8.11 sees a message indicating bad frame
length on transmit request messages in the log for SRB Token Ring
interfaces.
CR 19776: DataPath.
Selecting Reset Active from Site Manager causes a bus fault to
occur in DP if the primary interface of a circuit becomes
inactive.
CR 19791: DataPath.
Source Routing Bridge is not configured properly on standby Token
Ring redundant interfaces. Token Ring interfaces require that you
configure the first active interface for a circuit, but not for
standby circuits.
CR 19559: VINES.
Bouncing a VINES interface may result in panics, bus errors,
and/or orphan buffers in the router.
CR 19780: OSPF.
An OSPF adjacency may fail to form because of a sequence number
mismatch if the master has no LSA¹s to send in its Database
Description Packet.
CR 18278: IPX.
Server names are not identical to the name contained in learned
packet. Some devices use all 48 characters in the server name
field rather than stopping at the null character. This causes
connectivity problems.
CR 19199: IPX.
If you configure an outbound SAP network or name level filter to
advertise a particular service or group of services with a specific
cost (hop), the cost defined will be advertised in all services of
a particular type (that is, 0x0004) if the filter matches one of the
services in this particular type.
This occurs on outbound only and occurs with SAP name and network
filters.
CR 19773: IPX.
The Service age is not set to zero after SAP updates are received.
This causes the services to age out the IPX Service Table and then
be relearned.
CR 19846: AppleTalk.
A bus fault occurs when a slot receives a certain RTMP
packet on an interface configured with AppleTalk.
CR None: During the execution of power-up diagnostics for net modules for
an ASN router, the instruction cache fails to maintain
coherency during the beginning stages of the net module execution.
Because all net module diagnostics load to the same address
space, the instruction cache must be flushed before the CPU jumps
to the newly loaded code. If the instruction cache is not flushed,
it can ³hit² when fetching an instruction for the newly loaded
image, resulting in the CPU fetching ³stale² data; that is,
instructions that are left behind in the cache from the previous
module diagnostic image.
