Revision Notes for Router Software 8.12 rev 9
============================================================================
SITE MANAGER COMPATIBILITY
=============================================================================
Router Version is managed by Site Manager version
v8.12 through 8.12/8 ------------------> V2.12, V3.00, 3.00 Rev 1,
3.01 Rev 1
8.12 fix 9 ------------------------------> V2.12 fix 1, 3.01 Rev 2
(only necessary to enable you to configure
wfIpInterfaceTrEsArpType correctly. See CR 22267 for details)
-----------------------------------------------------------------------------
Revision fix 8.12/9 corrects the following problems:
=============================================================================
CR 19177: VINES.
After a slot resets, VINES may stop forwarding packets to
some networks even though the network table in the MIB is correct.
CR 19507: DLS.
The DLSw Destination MAC address filters do not work properly.
As a result, the DLS Drop All Filter fails to
drop packets according to the filter precedence logic that
has been defined.
CR 19126: DLS.
DLSw destination MAC filters do not work properly. Users
operating PC's running SNA 3270 emulation software are allowed
to access the Destination MAC addresses 0x400000031723 and
0x400000000007, both of which are restricted.
CR 21998: IPX.
Dynamically adding, deleting, or modifying the IPX SAP server or
network filters using Site Manager will sometimes cause
a slot fault, which is generated in the form of a bus or watchdog
error.
CR 22085: FTP.
When you use the FTP software package QVNET to transfer a file to
a router, a tag violation error occurs.
CR 22397: TCP.
Disabling and enabling the DLS base causes an error when you have
approximately 400 TCP connections (state 3) on a router.
CR 21497: IP.
Dynamically configuring OSPF summaries may cause routers to
advertise OSPF summaries with incorrect masks, thereby preventing
access to routes summarized within those summaries.
CR 22188: Source Route Bridge.
Source Route Bridge (SRB) filters fail on HSSI and SYNC media.
The SRB traffic filters you enter in Site Manager in are in
non-bitswapped format for all media types. These traffic filters
fail on SYNC and HSSI media when the MAC addresses (entered in
Site Manager) are compared to a bitswapped MAC address that exists
when frames get bridged from Token Ring to HSSI/SYNC.
CR 19902: VINES.
Customer enhancement to provide Ethertype 0x80C4 on Ethernet to
enable native VINES support on FDDI and to support the
interoperability of bridging (FDDI to Ethernet) and routing
(Ethernet).
CR 22610: VINES.
A neighbor entry on the slot may cause an invalid next
hop pointer because of a timing error. As a result, that neighbor
and all of the servers it knows about become unreachable from the
router. The router will be able to ping its neighbor, but several
of the servers/routers behind the router that reside on other slots
will be unable to ping through this router.
CR 19627: Token Ring.
A fault may occur on an AN router upon receipt of a source route
frame that contains only the standard source route LLC header and
its associated RIF field.
CR 22267: MIB.
You cannot properly configure the 'TR End Station ARP Type'
parameter in Site Manager revisions 3.00 through 3.01/rev1
when interacting with 8-series router code versions up to
8.12/fix8. This problem is caused by an IP Interface MIB parameter
inconsistency between versions 8.12 and 9.00.
Support for 'TR End Station Arp Type' was implemented in 8.11/fix2
and 9.00/rel. The attribute wfIpInterfaceTrEsArpType was added to
both the 8.10 and 9.00 MIB revisions but at different offsets,
thus preventing 3.00/3.01 users to set this attribute dynamically
against an 8.12 router version.
To use this MIB attribute for 8.12/fix9, you MUST consider the
following:
o Update previous configurations and use the correct version of
Site Manager when implementing future configuration changes.
o Configuration files created by version 2.12/rel or earlier
will be upgraded automatically when booted on a router running
8.12/fix9 to correct the MIB inconsistency and preserve the
original attribute setting.
o Site Manager 2.12/fix1 and 3.01/rev2 users will now be able to
configure this attribute dynamically against 8.12/fix9. If you
are using Site Manager version 2.12/fix1 or version 3.00 or
higher, you MUST upgrade your router software to version
8.12/fix9 (minimally) to correctly manage this attribute.
CR 20863: DECnet.
If you bounce a DECnet circuit while it is learning adjacencies,
bus errors may occur.
CR 22628: OSI.
OSI routing may stop whenever a reset occurs on a slot that routes
OSI traffic. This failure condition occurs after you manually
reset a slot or after it encounters a software failure (fault,
resetting a slot).
CR 13463: IP.
When upgrading router software from 8.01/4 to 8.10, the
processing of multiple ARPs could result in a hogs bufs
condition.
CR 22814: IP.
Removed changes for CR 13523 (introduced in 8.12/8) pending
resolution of the problems identified in CR 22814.
CR 22502: Token Ring.
A fault in the tms380 driver may occur when a Token Ring card
(quad or dual) that is running DLS attempts to initialize
interfaces on a slot that supports over 100 TCP connections. The
failure occurs because the driver code fails to wait long
enough for the token diagnostics to complete on a busy system.
CR 23182: IP.
An OSPF Point-to-Point interface fails to receive Hello packets
from its neighbor, causing an established adjacency
to go down. This condition may occur in environments in which a
default route is used, thus affecting those interfaces that
receive packets destined for the default route.
CR 22020: LLC.
If you change the Source Route Bridge Ring ID dynamically, DLSw
fails, preventing connections established over DLSw (SNA and
NetBIOS) from functioning.
-----------------------------------------------------------------------------
Revision 8.12/8 corrects the following problems:
==============================================================================
CR 17620: Frame Relay.
Certain Protocol Prioritization/Outbound Bridge Filters over Frame
Relay cause ARP to erroneously drop ARP frames.
CR 20237: X.25.
X.25 PDN connections are off by 1 when accepting calls.
For example, when you set max_connections to
a value of 2, the service allows 3 calls. Likewise, when you set
max_connections to a value of 4, the service allows 5 calls.
CR 19805: MIB.
MIBII ifentry iftype 46 does not exist for HSSI interface.
Therefore, when attempting to run a WAN summary against the HSSI
port, the field displays all zeros (0000s), and never updates.
CR 21332: DLSw.
Dynamically deleting the DLS slot IP address disrupts the existing
TCP connections on other slots on a router.
CR 16192: DLSw.
When using DLS between LANDP/DOS and the host system, the XID
format 8 is dropped, preventing LANDP/DOS from receiving the
negative XID response. As a result, LANDP/DOS and the host are
unable to establish a connection.
CR 19600: DLSw.
DLS creates invalid wfDlsConnectionEntry entries on local switch,
causing a panic in dls_netbios.c, which in turn causes all NetBIOS
and SNA sessions to bounce.
CR 21331: TCP.
TCP peers fail to reconnect when you dynamically delete and later
add a DLS peer entry that has already established a TCP
connection.
CR 19502: SYNC.
When you enable the RTS/CTS option (used to provide sync line flow
control to some DCE equipment) on an AN or an ASN router,
the synchronous interface goes down, preventing it from
transmitting and receiving frames.
AN---------|Break Out Box|------------BLN
sync sync
The Break Out Box is configured to act as a modem eliminator.
CR 20131: PCAP.
Packet Capture receive filters on source or destination MAC
address and do not work on TOKEN or FDDI.
CR 13523: Source Routing Bridge.
A failure of IP Encapsulated source route traffic may occur under
certain circumstances immediately following the replacement of
router hardware. The problem occurs as a result of an unexpected
change to the Time of Day clock, which can be introduced by a
change in hardware. This is considered a problem because IP
Encapsulation runs on a UDP based application that uses time
stamped sequence numbering.
CR 20679: MIB.
The MIB entry wfIfEntry.wfIfOperStatus used to indicate that
an interface is disabled is not set correctly for
Token Ring, Ethernet and Synchronous interfaces. The current value
is set to 3 for TESTING. This value should be set to 2 for DOWN.
CR 21555: IP.
An IP error occurs continuously after booting a router, and IP
fails to recover. The problem occurs only when attempting to
process an invalid host adjacent host, whose nexthop
interface address does not exist.
CR 20955: PING_MIB.
When issuing a series of pings, the ping MIB may receive
echo replies out of sequence, therefore causing the ping MIB to
report invalid positive values for total and maximum delay.
CR 21639: X.25.
A panic in mib_ent.c occurs when you add or delete X.25 VCs.
VCs get added and deleted when sessions are being added or timed
out or when a router tries to start a session to a remote site but
the remote end is not operational.
CR 21269: DECnet
When you issue the SHOW DECNET CIRCUITS command under certain
circumstances, the link module type is displayed incorrectly. If
the link module that resides in the slot is an FDDI card, the
script shows it incorrectly as a Token Ring card
under the circuit type. The script reflects the link module type
correctly if the card is either a Token Ring or an Ethernet.
CR 21893: DLSw.
NetBIOS Name recognized frame is duplicated by DLS in a local
switch configuration with Source Routing Bridge enabled.
CR 19206: DLSw.
A fault can occur in tcp_prep_xbuf.c when establishing DLS
connections.
CR 21944: Source Routing Bridge.
A Source Route frame whose destination address is a Wellfleet
Group MAC Address does not get filtered by Source Routing Bridge
(SRB) traffic filters on a Token Ring interface when the SRB
traffic filters are configured for the real destination address
and not the Wellfleet group MAC address.
CR 21268: SCRIPTS.
If you have configured more than one SNMP Manager and issue the
the SHOW SNMP COMMUNITY command, the output format for the SNMP
Managers display incorrectly on your screen. Insert a carriage
return at the end of the first SNMP Manager to ensure that they
format correctly.
CR None: VINES.
A router may experience memory loss or corruption when numerous
VINES routes are aged simultaneously.
CR 21691: DLSw.
When you configure a DLSw filter with the action "Forward to
Peer", any matching packet is not forwarded. The log indicates
that the filter rule matched successfully, but shows an
invalid IP address.
CR 19711: Scripts.
The SHOW HARDWARE SLOT command generates too many columns on your
screen, causing Link Serial Number of 1346 wraps on an 80 column
display down to the next line. For example:
[1:1]$ show hardware slot
Hardware Information per Slot
-----------------------------
Slot Processor Processor Processor Link Link Link
Module Revision Serial No. Module Revision Serial No- ----------------- --------- ---------- ------------ -------- ------
1 Access Node 129 00000542 module#1045 2147483777 134
6
CR 16330: SCRIPTS.
When you issue the script SHOW STATE ALL command with Frame Relay
or BGP configured, the state.bat script calls the fr.bat script
with invalid parameters. This causes the fr.bat script to display
its help information.
CR 21835: IP.
A router acting as a BOOTp gateway fails to forward BOOTp replies
back to the requester over a Frame Relay interface configured in
Group Mode.
CR 21553: DLSw.
When using SRB Encaps on a Token Ring interface,
wfDlsInterfaceEntry.7 & wfLlcInterfaceEntry.24, the XID is not
getting passed to the Token Ring. The RIF field has the explorer
bit still asserted.
CR 19724: IP.
The route tables for each slot are inconsistent. When a packet
destined for a network that is missing from a particular slot's
route table is forwarded, the packet is sent out the Default
Route. The default router receives the packet, does a lookup for
the destination, and the packet is sent back to the original
router on a different slot/interface. Because this slot
has a correct route table, the packet is forwarded out the correct
interface.
CR 22390: TCP.
TCP connections for an unconfigured peer may fail to reach a full
"ESTABLISHED" state, preventing DLSw connectivity between the
peers. This condition applies only to connections from Write to
Read port.
CR 22: TCP.
When you have approximately 400 TCP connections (state 3) on a
router and you disable and enable the DLS base
s wfDls.2.0 2;commit; s wfDls.2.0 1;commit, and error occurs.
CR 21673: DLSw.
SDLC sends RNRs and never exits in a half duplex mode.
-----------------------------------------------------------------------------
NOTE:
We have created a revised version of the 8.12/7 revision notes to reflect
a minor change in the build. CR 21960 has been removed from 8.12/7 and
incorporated into 8.12/6. The revised version shown below reflects this
change. Ignore the previous version of 8.12/7 that you received.
-----------------------------------------------------------------------------
Revision 8.12/7 corrects the following problems:
==============================================================================
CR 22021: VINES.
VINES ICP metric notifications are sending internal metrics
rather than Sequenced advertised metrics. As a result, significant
delay occurs when resending packets to clients.
CR 21587: VINES.
The Sequenced RTP bit in the compatibility byte should be set if all
neighbors on a segment support sequenced RTP packets.
CR 21590: VINES.
The Sequenced RTP bit in the RTP Machine type byte should be set
if the router supports sequenced RTP.
CR 19747: NVFS.
When you attempt to hot-swap a Flash card on an AN router, the
Technician Interface generates a message indicating that
the Flash card is corrupted. This is an invalid message. The Flash
card is not corrupted.
CR 21174: IP.
A Frame Relay interface whose address resolution type is set to
"INARP" experiences permanent buffer loss if you attempt to
establish a connection within the IP network of the
Frame Relay cloud and the end station does not have an entry in
the ARP table.
-----------------------------------------------------------------------------
Revision 8.12/6 corrects the following problems:
==============================================================================
CR 21960: IPX.
Hogsbufs may occur in ipx_rip_sap_request_act when receiving IPX
RIP requests.
CR 19338: PCAP.
Packet Capture displays Tx and Rx packets out of sequence on a
MCT1 circuit. Tx packet (A) displays after the Rx packet (B) in
the capture file, even though packet (A) is sent before
packet (B) is received.
CR 18964: IP.
A router configured on a Token Ring interface with end station
support enabled will flood the log with mapping messages at a rate
of 10 to 12 mapping messages per second, causing the log to wrap.
CR 19548: MCT1.
Excessive traffic across multiple logical lines on Port 1 of an
MCT1 link causes delayed response to LMI on Port 2 of the same
MCT1 link.
CR 15703: OSI.
OSI area address aliases are not being advertised in IS hello
messages; only the main NSAP is being advertised. As a result,
adjacencies cannot be established between the end-system and
the Bay Networks router.
CR 19249: Switch Services
An auto-terminated DoD circuit configured on an ISDN-B channel
will not be created if the B-channel is in use when the
auto-termination reset timer expires.
CR 19606: DVMRP.
When you delete the DVMRP protocol from a slot or multiple slots on
a router, the DVMRP.exe file continues to reside in the
routerıs memory address space. This can lead to inefficient
use of available memory addresses for other protocols attempting
to use that space.
CR 18928: FTP.
Issuing multiple commands during an FTP session and then
changing directories to a different slot can cause a slot to fault.
CR 18246: NVFS.
A file that contains an illegal filename cannot be deleted from
a Flash card.
CR 17553: DLSw.
If you remove the cable between the router and the controller,
the DLS/SDLC and SYNC do not display a message notifying you
that the cable has been removed.
CR 20165: GAME.
The wall clock timer that runs on FRE-060 boards is slower than the
timer running on the FRE-040 boards. As a result, log events get
printed out of sequence.
CR 18771/
CR 20101: BNX Switch.
When you set the date and time on a router by specifying the
"date" command (using the Technician Interface) with invalid
alphanumeric characters, the clock may reset hours/minutes to
00.00.
CR 18735: Technician Interface.
When you enter the "Diag" and "Reset" commands from the Technician
Interface without specifying a slot, the router performs
diagnostics on all slots and then reboots each slot. An
enhancement request has been issued to provide a confirmation
message that asks the user to decide whether or not to perform
diagnostics on each slot or reset all slots.
CR 19909: NVFS.
While attempting to hot-swap a Flash card, a file on the Flash
got corrupted when the first character in the filename changed
to an exclamation point ("!"). Attempts at deleting the file
failed, thus leaving no other option but to reformat the Flash
card.
CR 20410: FTP.
If you attempt to change to a non-existent directory/file system
on a router using FTP, a watchdog panic error occurs when you
attempt to change directories subsequently.
CR 18534: IP.
In most configurations, the MIB variable
wfIpBase.wfIpBaseHosts.0 does not accurately represent the total
number of hosts that the router knows about. While the total
number of hosts should match the number of instances in
wfIpNetToMediaEntry, the actual number seems to be larger.
CR 19486: Hardware-Diagnostics
When you hot-swap a link module from a BLN or a BCN router, the
FAIL LED remains on. Customer enhancement request to turn LED off.
To turn off the FAIL LED, enter the following command:
diag -1
