Revision 11.02/2 corrects the following problems:
=============================================================================
CR 32039: DLSw.
A problem exists in 11.00/6 where a router may fail to identify
the RFC version of its remote peer, thereby preventing it from
forwarding any ICANREACH packets and preventing DLS connections
from establishing.
CR 31629: ARN.
The internal modem on an ARN router does not completely transfer
(xmodem/ymodem) files with its default settings. The modem allows
only about 20-29 percent of the file to be transferred.
CR 30535: DECnet.
DECnet unicast traffic using PDN/X.25 does not get forwarded out
the synchronous interface on AN and ASN routers.
CR 31980: IPX.
In router running software version 11.01 and later, a slot will
start aging all IPX routes in its tables, even if it doesn't own
the route. When the route age gets to three times the update
interval of the interface on that slot, the route becomes
unreachable and is removed from this slot's table and the route
tables of the other slots.
CR 32354: IPEX.
An interoperability issue exists between 11.01 (remote) and
11.02 (central) routers. This condition occurs only when the
central (BCN) router is booted with an 11.02 image and the remote
(AN) router is booted with a 11.01 image.
CR 32498: OSI.
The router experienced a fault when attempting to boot with
OSI and IPX.
CR 30327: DLSw.
When you terminate DLSw on a ARE slot (ATM LANE), router
performance degrades after the host's MAC address is aged out from
the cache. After the MAC address is aged out, performance
degradation begins shortly thereafter.
CR 30919: OSI.
AN OSI adjacency will not always come up between two routers that
are connected via PPP. This problem is evident about 80% of
the time. Bouncing the interface may resolve this problem, but not
in all cases.
CR 31075: DLSw.
A problem exists in software version 11.00 in which the router may
fault when aging out the DLS test table after DLS connections have
been established. This causes the router to fault with tag
violation errors or bus errors.
CR 31297: DLSw.
The connections in the DLS LLC1 connection table are incorrect at
router1 when there is more than 1 connection to the same
destination. The error displays at router1 when both end stations
have a "connected" LLC session to the host.
CR 31449: IP.
When running a router in ISP mode, configuring a log and/or accept
traffic filter causes a bus error to occur.
CR 31510: QLLC.
When you set wfX25QllcAddrMapOptions with option 2, the AN router
locks up, requiring you to reboot to restore router operations.
The lock-up occurs after a X.25 call is placed to a AS/400 for a
downstream PU 1.0 device.
CR 31590: DLSw.
A router may fail to forward ICANREACH SSP messages to a remote
peer if that router receives XID polls before fully establishing
TCP connections.
CR 31718: ATM.
In an ATM Classical IP environment, an MCP error occurs on an
ATM slot when the AtmArpServerRegInterval timer expires. The
default for this timer is 15 minutes for an ATM client, and you
cannot change this parameter in the MIB, even though Site Manager
states otherwise.
CR 31804: GAME.
A problem exist in the ARN Ethernet motherboard that prevents you
from configuring the buffer size. This could cause a problem in
an OSPF network where a Links Advertisement exceeds 1824 bytes.
For a large link state database, the Router Links Advertisement
will fragment but will not be able to reassemble if the packet
exceeds 1824 bytes.
You can set the buffer sizes to either 1824 or 4800 bytes on
non-token ARN routers. The default is 1824. This setting will be
saved in NOVRAM and will be read in at boot time.
Buffers can be carved from the Technician Interface as follows:
set wfKernCfgParamEntry.wfKernCfgParamDelete.1 1
commit
set wfKernCfgParamEntry.wfKernCfgParamBufSize.1 4800 (or 1824)
commit
set wfKernCfgParamEntry.wfKernCfgParamDelete.1 2
commit
reset 1
CR 31859: IPX.
When bouncing a ISDN BRI interface for a DOD circuit, the router
experiences a bus error when the DOD circuit is the next hop
address for an IPX static route. A bus error does not occur if
there is not an IPX static route configured for that circuit.
CR 32524: PPP.
After upgrading to router software version 11.02, PPP connectivity
problems occur because of the new defaults for the MRU size.
There are two new MIB parameters that you can set to comply with
the suggested MRU of 1500 in RFC 1661:
wfPppLineEntry.WfPppRfc1661complianc
wfSwservOptsRfc1661compliance
CR 26853: DLSw.
After disconnecting and reconnecting the SDLC lines to the PU
or to the host on an SDLC-to-SDLC connection, a recovery problem
occurred.
CR 26870: SNMP.
An enhancement request to allow you to set a threshold on the
router for the maximum amount of buffers that SNMP can allocate.
CR 27393: LB.
If you configure LB in dynamic mode and you disable LB globally,
the router experiences a bus error.
CR 28318: APPN.
Configuring HPR over a SDLC link that connects two routers
prevents DLUR/DLUS sessions from establishing.
CR 29853: BGP.
Setting up Black Hole Routing to respond with the message "ICMP
Unreachable" does not work. Instead, it responds with
the message, "Does Not Respond".
CR 29858: IP.
A VBM error occurs on the ARE when processing UDP checksum.
CR 30033: DLSw.
DLSw/SM should support MAXPDU > 2057 on SDLC links, but it does
not.
CR 30070: IP.
Nexthops to destination networks remain in route table even after
disabling circuits.
CR 30610: ARE.
Running the script "show process cpu" on an ARE while running
traffic causes watchdog panics.
CR 30853: ARE.
DLSw experiences a problem when an XID poll sequence reconnects
an APPN session.
CR 30885: BGP.
You are unable to change the local_pref of routes that have an
origin of incomplete on a BGP Accept Policy.
CR 31054: AT_Dial.
When a USR modem is attached to a quad or octal sync module, no
data gets passed. The modems call/ans and connect but do not get
passed the LCP configuration. The "Sending LCP Configuration
Request" packets are being seen, but there are no LCP
config/requests received at either router.
CR 31062: IPEX.
X25/IPEX does not pass called/calling address.
CR 31262: DLSw.
A BLN router configured with SDLC and Token Ring produces a fault,
triggering service termination and a system restart.
CR 31315: SS/BACP.
Traffic reduced but BAP secondaries remain operational. Late
BAP messages are ignored.
CR 31517: ATM LANE.
Routers running router software 11.00 or later will fault on an
ARE interface upon receipt of an IP multicast packet.
CR 31546: DLSw.
V20 to V20 unconfigured peer connections do not establish.
CR 31644: QLLC.
A PC3270 client cannot reestablish a session after rebooting.
CR 31830: DVMRP.
Configuring DVMRP on a 100BASE-T appears to fault on FRE2s,
thereby disabling AREs running DVMRP. The AREs MCP and the FRE2
faults in dvmrp_cache.c line 800 (looks like RPC failure).
CR 31856: SMDS.
Unable to forward IP datagrams to destinations via an SMDS link
when the datagram size (beginning with IP header and including
payload) is exactly 54 or 55 bytes less than the configured MTU
on the SMDS interface of each of the routers.
CR 31926: Translation Bridge.
Translation Bridge (XB) stops caching RIFs for no apparent reason.
Connectivity is not affected because the router still sends out
AREs.
CR 31957: AT.
A VBM CPU read midpage error can occur on a ARE routing AppleTalk.
CR 32016: NBIP.
A bus error occurs in the NetBIOS over IP code on the router after
a slot resets or after a boot.
CR 32111: OSPF.
When LSU's are multicasted out, the router does not fill one
packet fully before sending out another packet. The same holds true
for sending out ACKS. As a result, for an update event (LSU's plus
ACK's) that can be completed with the exchange of 23 packets, the
router exchanges approximately 350 packets.
CR 30925: ATM.
Routers running router software 11.00 or later will fail in
address registration if you specify an ATM prefix of 45.
CR 31028: DVMRP.
A problem exists in router software 11.01 in which IP multicast
traffic may not be forwarded out of an interface on a
slot for up to 5 minutes after the slot is reset.
CR 31182: BGP.
When BGP goes down, BGP routes authored by remote slots are not
deleted.
CR 32088: ATM LANE.
An ARE configured with Token Ring LANE and IP Token Ring End
is LE-ARPing for a MAC instead of for a RIF.
CR 26324: IPX.
Version 8 IPX MIB information still present in configuration
after upgrading to version 10. This produces a configuration file
that takes up additional flash space, and produces Version 8 IPX
MIB objects that are no longer valid within the config file.
CR 30410: Source Route Bridge.
The router experiences bus errors when adding a Source Route
bridging circuit when Source Route Bridging has been globally
disabled.
CR 31710: IP.
A problem exists in router software version 8.12 through 11.01/1
in which a gate that exists is being killed by other slots after
having already been killed by the original slot.
CR 32046: Source Route Bridge.
If you disable the Source Route Bridge (SRB) base when booting the
router, a bus error may occur.
CR 20225: Switched Services.
Log messages for Switched Services-- including Dial backup, BOD,
Dial on Demand-- lack sufficient information to clearly describe
the operation taking place.
CR 28170: Router Redundancy.
Enhancement request to add a new attribute (wfRRedundWarmBoot) to
the wfRRedundGroup object. This new object allows you to
dynamically change the role switch mode of the routers between
"warm boot" (method used in software version 11.00 and earlier)
and "hot swap" (method used in software version 11.01 and later)."
Please note that the "warm boot" and "hot swap" versions are
incompatible, therefore, all routers running Router Redundancy must
be running the same version.
-----------------------------------------------------------------------------
Revision 11.02/1 corrects the following problems:
=============================================================================
CR 30791: ATM.
Routers running router software 11.00 or later will fail to
acknowledge LE_ARP responses from the C100, causing intermittent
connectivity problems between the router and the switch.
CR 31464: Translation Bridge.
A NetBIOS session fails to establish itself after the
translation bridge base is bounced. This occurs because the
translation bridge drops the NetBIOS datagram packet sent by the
server after bouncing the translation bridge base. As a result,
the NetBIOS datagram packet never reaches the Enet (LB).
