Revision Notes for Router Software 8.12 rev 2
============================================================================
SITE MANAGER COMPATIBILITY
=============================================================================
Router Version is managed by Site Manager version
v8.12 V2.12, V3.00, 3.00 Rev 1
8.12 fix 2
------------------------------------------------------------------------------
Revision fix 8.12/2 corrects the following problems:
=============================================================================
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
non-fully meshed environment.
CR 18910: Switched Services.
A Dial-on-Demand connection that is brought up and down
repeatedly while operating with a specific modem type can cause
intermittent tag violations on a BLN router or cause an AN router to
hang.
CR 16861: Translation Bridge.
Translation Bridge (XB) will cause a hogs bufs condition when
caching 1000 RIFS.
CR 19664: Source Routing Bridge.
A race condition exists between circuits running XB on the same
slot. As a result, XB produces a bus error while flushing messages
after the router is booted.
CR None: X.25.
Site Manager would not build due to missing comments in X25.mdl
file.
CR 17873: Switched Services.
When you configure the primary line on the COM1 port with external
clocking on an ASN router, the COM1 port fails to initialize
successfully. This condition occurs because the primary line is
initialized before the ISDN/BRI, thereby causing the ISDN to
overwrite the pins for the external clock when it comes up.
CR 19745: DLSw.
In an environment where numerous DLS connections (40 plus) are
being established and TCP and LLC are in a congested state, a bus
error can occur, causing DLS to be reinitialized.
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 13373: DLSw.
When running DLSw in a heavily looped Source Routing Bridge
environment, DLSw may panic when creating a MIB instance.
CR 19998: LLC.
The T1 timer associated with LLC2 sessions is timing out
prematurely, causing frame rejects to be transmitted
incorrectly. This condition occurs in situations in which there
is heavy traffic and many PU's and LU's.
CR 19721: LB.
When attempting to connect to a NetWare server, the source and
destination MAC addresses in the IPX GNS response packet gets
corrupted through Ethernet-ATM-FDDI-Ethernet bridging.
CR 19997: LLC.
An LLC2 session that receives a TESTf after it has already been
established will cause the session to disconnect. This should
happen only for a TESTp frame, not for a TESTf frame.
CR 17792: Source Routing Bridge.
SRB traffic filters configured on the destination address in a
Source Route Frame are not working correctly. The actual
destination address is moved to the end of the frame, and
a group address is inserted in its place. As a result, the
actual destination address does not match the specified
destination address in the filter rules.
CR 18861: OSPF.
An Area Border Router(ABR) may fail to generate a new Router Links
Advertisement for the Backbone router if it loses connectivity to
an attached area.
CR 20343: MCT1.
It is possible for logical lines to go "deaf" on an MCT1 port
configured with multiple logical lines. In its attempt to recover,
logical lines will not see incoming frames.
CR 15954: Source Routing Bridge.
Frames configured to be dropped by Source Routing Bridge filter
instead are translated and forwarded by XB to the transparent
bridge side of the network. This condition occurs for both AREšs
and for SRFšs.
CR 19947: IP.
A configuration parameter is required that will enable users to
select whether IP Broadcast messages are sent out as STEšs or
AREšs when end station support is enabled.
CR 18684: IPX.
IPX traffic may stop being received intermittently over an ATM
link, causing a potential loss of connectivity.
CR 20054: VINES.
In a redundant VINES network when one of the routes becomes
unavailable, VINES fails to reconverge. This causes the existing
route to age out, preventing alternate routes from being learned.
CR 18859: OSPF.
In the OSPF MIB, the variable
wfOspfGeneralGroup.wfOspfAreaBdrRtrStatus does not accurately
reflect the true status of the router. The variable appears to
indicate that only a second AREA is configured and enabled, which
doesnšt necessarily mean the router is actually an AREA Border
router at the time.
CR 19428: IP.
In an IP host-only and spanning tree environment, changes in the
spanning tree topology may cause some routers to lose IP
connectivity with other devices.
CR 19429: SPAN.
The router can change a Spanning Tree port state from blocking to
forwarding under specific circumstances, and yet not send a
topology change notification as required.
CR 20338: AT.
In a redundant topology under certain circumstances, AARP's are
not generated when NBP Forwarded Requests need to be sent to the
next hop router.
CR 20413: EGP.
If a router is configured for EGP on an interface and receives a
fragmented frame, the router produces an error.
CR 20056: OSPF.
Virtual adjacencies frequently get stuck is the exchange start
state when the backup soloist is enabled on an OSPF router. In
addition, when OSPF restarts, an orphaned buffer occurs during the
attempted formation of the virtual adjacency.
CR 19762: DLSw.
When upgrading to 8.11 or above on a router running DLSw on an
Ethernet Interface, A Tag Violation/Slot Reset may occur on the
Ethernet Slot if a pre-8.10/8.11 configuration file is used. A
typical example would be upgrading from 8.01 to 8.11
RELX and using the original 8.01 configuration file.
CR None: GAME.
Enhancement request to the gate tracing (gidtrc) option of Debug.
This enhancement allows users to specify a maximum threshold value
for saving to a trace buffer two events that are useful in
performance analysis: the time between idles and the length of
time a gate runs.
CR 13524: AN.
When you attempt to set the date for December 1999 on an AN
router, the system sets an incorrect date. For example:
> date 11/30/99 23:59:45
Nov 30, 1999 23:59:45 [GMT]
>
> date
Jan 131, 19100 0:00:11 [GMT]
CR 20697: IPX.
When you boot a BN router when IPX is initializing, a bus error
occurs.
CR 20637: Switched Services.
In a dial back up configuration with MCT-1 as the primary
interface, the router will log transmitter time out messages
continuously after the primary interface is bounced.
CR 20724: IP.
Request to enhance the table structures in the fast forwarding
table to reduce the processing time required by IP to update the
table.
CR 20761: DLSw.
DLs remains connected to the router after SNA client is
disconnected from the router.
------------------------------------------------------------------------------
Revision fix 8.12/1 corrects the following problems:
=============================================================================
CR 19846: AppleTalk.
A bus fault occurs when a slot receives a certain RTMP
packet on an interface configured with AppleTalk.
CR 18876: LLC.
When a Token Ring interface configured for LLC2 bounces, a bus
error and/or a watchdog timer expired fault occurs.
CR 19668: LLC.
When a slot receives a certain LLC packet on a Token Ring
interface configured for LNM, the slot experiences a bus error.
