Release Abstract

This document serves as the Software Release Notice (SRN) for this release of B
-
STDX software. The
following sections describe the switch software revision for this release and the hardware that

it supports. It
also provides a list of current Ascend documentation you may need to reference for complete information.

1.1

Supported Software

Release 4.1 introduced a new version numbering scheme. In addition to the four
-
part version ID (ex. 4.1.3.0)
there

is an additional “Software ID” portion, that consists of a letter code followed by a spin number (ex. R301,
where R represents released software). To view the complete software tag, issue the
show software

command from a switch console to display the leve
l of software currently running on each card. You can also
issue the

show software flash

command to see the software that resides in the CP FLASH area.

This release is bundled as CP version 04.02.05.00, IOPA version 04.02.05.00, IOPB version 04.02.05.00, a
nd
IOPC version 04.02.05.00. The following list describes specific switch software and build IDs contained on the
software installation disk:



cp1.rom

version 04.02.05.00 (Software ID: EC
-
R000009F9) supports the Control Processor cards. This file
is the CP

application code (version 04.02.05.00). This file consists of two parts, the application code
portion (04.02.05.00) and a CP1 boot flash code portion (version 04.02.04.00).



ioptypea.rom

version 04.02.05.00 (Software ID: EC
-
R00000836) supports the UIO/T1/E
1/DSX
-
1 IOP
cards. This file consists of two parts internally: an IOPA application code portion (version 04.02.05.00) and
an IOPA boot flash code portion (version 04.02.00.03).



ioptypeb.rom

version 04.02.05.00 (Software ID: EC
-
R0000058B) supports the HSSI/
ATM DS3/ATM E3
IOP cards. This file consists of two parts internally: an IOPB application code portion (version 04.02.05.00)
and an IOPB boot flash code portion (version 04.02.06.00).



ioptypec.rom

version 04.02.05.00 (Software ID: EC
-
R0000004BC) supports t
he ATM UNI CS IOP and
ATM IWU OC3/STM
-
1 cards. This file consists of two parts internally: an IOP3 application code portion
(version 04.02.05.00) and an IOPC boot flash code portion (04.02.02.01).

Feature

Description

Distributed OSPF

The Open Shortest Path First (OSPF) function is no longer centralized at the CP.
It has been distributed

so that each IOP can now process OSPF functions.
Distributed OSPF enables the IOPs to make routing decisions. With this new
architecture, each IOP has full knowledge of the network topology and is
therefore able to make independent routing decisions.

Dis
tributed OSPF reduces the load on the CP in intermediate nodes because the
IOPs can forward packets without using the CP. This does not increase network
background traffic, as the CP continues to aggregate and propagate the OSPF
Link State Advertisements (
LSAs).

Priority Rerouting

Priority Rerouting allows a PVC configured with a higher priority to select a
more efficient path (one that satisfies its QoS) than those
PVC
s configured with a
lower priority. As it selects this path, the higher priority PVC can

choose to
redirect lower priority traffic to a less efficient path. This guarantees that the
network will always give preference to higher priority PVCs, even during periods
of congestion or link failure. This preference provides a higher percentage of up
-
time, an increase capacity to burst past the guaranteed QoS, and shorter delays.

PRAM Kermit

Enables a customer to kermit a PRAM image directly to the switch via the switch
console. This feature can simplify the initial switch commissioning.

Multilink
PPP

Multilink PPP allows two or more PPP links to be combined into one logical link
to provide greater effective bandwidth on the multilink PPP link than on any of
the individual links. There can be

up to 32 links in each multilink PPP bundle.
Multilink PP
P is a method for splitting, recombining, and sequencing datagrams
across multiple logical data links. See the

Cascade Documentation Set
Addendum

for instructions on configuring a multilink PPP connection.


All IOP Type A cards support the multilink PPP pr
otocol (MLP
-
1490) and
include the following modules: E1
-
PRI (ISDN), T1
-
PRI (ISDN), Unchannelized
T1/E1, Channelized T1/E1, 4

ATM Features

ATM Redundancy

This release supports redundancy on the ATM IWU

OC3/STM
-
1 cards.

Single OSPF Domain

This release provides Cascade OSPF routing between B
-
STDX and CBX 500
switches. A single OSPF routing domain can support a network that contains
both B
-
STDX and CBX 500 switches.


OSPF Delay Metric

The OSPF delay metr
ic allows for PVC circuits (
ATM circuits only
) to be routed
based on an end
-
to
-
end delay routing metric.

ATM Direct Cell
Trunk

A Direct Cell Trunk enables a single OSPF routing domain in a network that
includes both B
-
STDX and CBX 500 switches. You can e
stablish
VC
s between
any B
-
STDX and CBX 500 switch, using either B
-
STDX frame
-

or cell
-
based
trunks or CBX 500 cell trunks. Routing decisions allow frame
-
based traffic
coming from the B
-
STDX to transit either frame or cell
-
based trunks. Cell
-
based
traffic
coming from the CBX 500 is restricted to routes, which transit Direct Cell
Trunks.

Multiservice
PVC
s

Multiservice
PVC
s refer to a virtual circuit in a mixed network of both B
-
STDX
and CBX 500 switches that can transit either frame or cell
-
based direct tru
nks in
any combination. The full integration of the B
-
STDX into the CBX 500 network
using a common trunking protocol enables this function. Multiservice PVCs
allow end
-
to
-
end connectivity between any pair of access interfaces which are
either compatible or

support interworking.

CLP Bit

Sets the cell loss priority on FR
-
ATM Service Interworking circuits.

Group Address

Broadcasts group address frames to specific addresses rather than a general
broadcast.

Country Code Prefix

Extends SMDS networks across international borders.

SMDS Address Mask

Enables migration from another vendor’s SMDS network to a Cascade SMDS
network.

Alien Address

Increases network scaleability by increasing the Alien Address capacit
y from

Frame Relay
Features


Frame Relay SVCs

This feature is available to users of the CascadeView/UX NMS Version
02.04.00.00 or later. If you are using Version 02.04.00.00 or later of the NMS,
you can now set and monitor switch
-
wide SVC configuration parameters on each
of your B
-
STDX 8000/9000 switches. See the
Cascade Documentation Set
Addendum

(part number 104
-
00102
-
00) for more information about Frame Relay
SVCs.

Zero CIR Frame
Relay PVC

To provide a best effort data service
, you can now configure PVCs with CIR
values of zero. End users subscribing to zero CIR services can burst to the port
speed if there is network bandwidth available to deliver frames, however the
network does not guarantee to deliver these frames. The disc
ard eligible bit of all
frames entering the network on a zero CIR PVC is set to one (eligible for
discard).

Frame Relay
Asymmetric CIR

Asymmetric CIR allows you to specify different QoS parameters in each
direction of a Frame Relay PVC.

ISDN Features


E1 ISDN I/O Module

This release adds support for the European E1 ISDN interface that supports 30 B
channels and one D channel.

European ISDN
Signaling

The ISDN access card supports European ISDN signaling standards (CTR4) as
well as switch
-
specific exten
sions as required.

Australian ISDN
Signaling

The ISDN access card supports Australian signaling standards (TS014) as well as
switch
-
specific extensions as required.

PAP

Password Authentication Protocol (PAP) provides a simple authentication
method using
a two
-
way handshake. This is done only upon initial link
establishment. With PAP, passwords are sent over the circuit without encryption
and there is no protection from repeated trial and error attacks.

CHAP

Challenge
-
Handshake Authentication Protocol (CH
AP) is used periodically to
verify the identity of a client using a three
-
way handshake. This is done only
upon initial link establishment. With PAP, passwords are sent over the circuit
without encryption and there is no protection from repeated trial and
error
attacks.

RADIUS

Remote Authentication Dial
-
In User Service (RADIUS) provides authentication,
authorization, and configuration information between a Network Access Server
and a shared Authentication Server. RADIUS is used to ensure security when
esta
blishing a Point
-
to
-
Point (PPP) connection to a Cascade B
-
STDX switch over
an ISDN remote access link. RADIUS supports PPP, PAP, and CHAP.

Frame Buffer Exhaustion

A problem was corrected whereby control traffic
could drive the buffer count below

the user
threshold, exhausting frame buffers and potentially
causing the reuse of a previously allocated buffer.

Multicast Over Cell Trunks

Multicast circuits no longer pass traffic to circuit
endpoints which are not members of the Multicast
circuit fol
lowing a cold boot of a switch. This
problem was previously observed when the circuits
were established over cell trunks.

stream
equipment goes down (C97
-
16731)

The problem whereby an Lport/Pport failure
on
C500 did not generate an alarm on PPP circuits in a
B
-
STDX has been corrected.

PPP circuits can’t come back after switch
reboot (OAM disabled) (C97
-
16845)

PPP circuits now come back after rebooting a B
-
STDX switch with ATM ports (OAM disabled).

Pram
sync causes circuits to go down on a
Ch DS3 (C97
-
17237)

Performing a PRAM Sync no longer causes circuits
to go down on a channelized DS3 card.

Translate OAM alarms to PPP alarms (C97
-
17585)

The system now generates a trap stating the circuit is
down due t
o OAM.

Crash address not cleared (C97
-
13576)

Crash addresses associated with Fatal Error
messages are now cleared when subsequent Fatal
events are encountered that contain a crash address
of zero.

After coldbooting B
-
STDX with Ch DS3
cards, circuits do n
ot come up (C97
-
17257)

Ch DS3 circuits now correctly come up after you
coldboot the switch.

IfType and IfNum descriptions are
inaccurate (C97
-

The system now displays the correct interface
descriptions.

No alarm when OAM F4 is Received (C97
-
16847)

The alarm is now displayed in the event window
when a Cisco 7500 and C500 is down and the C500
sends an OAM F4 alarm to the B
-
STDX.

Issue console prompt (C97
-
16796)

On a switch that is booted with no PRAM on the
CP, the console prompt is now displayed as
“>>”
(instead of “>”).

T1/E1 Transmit Driver

A problem with the transmit driver of the 10
-
port
DSX
-
1, 4
-
port T1, and 4
-
port E1 IOP cards has been
corrected. This problem previously caused transmit
buffer overruns, which in turn resulted in a garbled
fra
me. This problem occurred very infrequently and
only with very large frame sizes.

QoS

The problem whereby the QoS circuit parameters for
lost frames and octets intermittently would report
extremely large and unrealistic numbers following
circuit reroute
s has been corrected.

Bulk Statistics

Bulk statistics now calculates the correct QoS lost
frames and octets. A peak value is now maintained
for QoS statistics.

Multicast Traffic over ATM Cards

Issue

Resolution

IPX Traffic over ATM Cards (C97
-
16748)

The problem wher
eby IPX traffic received on an
Ascend PPP Lport and routed over an ATM UNI CS
or ATM IWU OC3/STM
-
1 card acting as a trunk
card, caused the trunk card to crash, has been
corrected. IPX traffic now correctly passes over the
trunk card, if the trunk is defi
ned as a direct cell or
OPTimum cell trunk. If the trunk is defined as an
OPTimum trunk, the IPX data is discarded, but the
trunk card will not crash.

PPP

The PPP link now recovers when a PPP link on a
channelized DS3 card connected to a router is
phys
ically disconnected and then reconnected.

(C97
-
15910, C97
-
16430, and C97
-
16552)

The problem whereby a 9000 with PPP Lports were
rebooted causing the PPP links not to come back
after the switch had recovered has now been
corrected. PPP links have now been

changed to
recover in this case. (Cases C97
-
16484 and

C97
-
16651)

When a new PPP connection is added to the switch,
the Lport now correctly reports its operational
status.

If a PPP link on a HSSI IOP goes down and up, the
card no longer needs to be reboo
ted to recover.

Missing Transmit Cells from PVC Statistics
(C97
-
16091)

If a virtual circuit is set up between two ATM UNI
CS cards in the same switch, the lower
-
numbered
slot now correctly reports cells transmitted on the
PVC statistics screen.

PVC O
perational Status

The code has been corrected to resolve a condition
where the PVC operational status would be incorrect
after modifying the PVC’s parameters or
administrative status. (Case C97
-
16387)

Intermittently PVCs would fail to come up after
being
added to a channelized DS3 card. This
problem has been resolved. (C97
-
16414)

If a channelized DS3 or HSSI card were latched
down and up again, the PVCs terminating on that
card would not recover. This problem has been
corrected.

4.2.1

General

Issue

Resolution

FR
-
ATM ARP Packets not compatible with
routers. (C97
-
13300)

The code now correctly sets address fields in the Frame
Relay packets to work with routers that have ARP or
Inverse ARP enabled when FR
-
ATM Service
Interwork
ing is selected on the B
-
STDX switch.

If a B
-
STDX switch was rebooted with a new
4.2 version of code, some IOP type A cards
would fail to come up.

The software was modified to correct this problem.

IOP cards crash after deleting circuits from the
card. R
unning BulkStats on the card
exacerbates the crash frequency.

(C97
-
16574)

The problem was fixed as follows:

-

A pointer to a BulkStats data structure now clears
the data after the structure is freed.

-

Deleting a PVC now causes the “back” pointer in a
doubly
linked list to be properly handled.

Internal diagnostics on channelized and
unchannelized E1 cards would occasionally
fail.

(C97
-
12200)

A software delay was introduced in the diagnostic
initialization routines to allow additional time for the
E1 framer to

transition into a framed state. The delay
guarantees that the framer will be in frame if all
hardware components are functioning correctly.

If the “any path” option is used in a defined
path circuit and a trunk on the path goes down,
the IOP which conta
ins the caller endpoint of
the circuit will crash. (C97
-
16539)

A local pointer variable which was uninitialized at the
start of the routine that calculates a defined path route
is now initialized correctly.

Displaying trunk statistics for an OPTimum
trun
k on an ATM CS or IWU card displays
question marks for the available bandwidth.
(SQA
-
2299)

OSPF and traffic delivery problems no longer exist on
ATM frame optimum trunks that are configured on
ATM CS/IWU cards. Circuits on a negative bandwidth
trunk load b
alance off of the trunk and new circuits
will not be routed over this trunk.

Bulk statistics were incorrect after a circuit
reroute. (C97
-
13386)

The software was modified to correct this problem.

Circuit Receive counters may be incorrect after
a PVC is r
erouted. (C97
-
12150)

The software was modified and the counters were
corrected.

PPP

Issue

Resolution

If intervening equipment between the switch
and the CPE experience an outage which
neither switch nor CPE detect at the physical
level, PPP will not c
ome up if the outage
exceeds the Config Request retry count.
(C97
-
16007)

The Link Control Protocol (LCP) now sends configure
requests continuously, instead of stopping after 10 retries.
The CPE device can now recover through a restart after
service is rest
ored.

NCP would initiate negotiations of Bridging
at link up. This may be a problem for certain
CPE’s. (C97
-
16007)

NCP will no longer attempt to initiate negotiations for
Bridging. However, the switch will negotiate if initiated
by CPE.

CHAP Challenge wo

The problem whereby inverse ARP failed on PPP
-
1490 translation FRAD
circuits which traversed a trunk which existed on the same card as the
ingress PPP
-
1490 Lport has been corrected.

OSPF Calculates Wrong
Value (C97
-
13015)

On an E3 trunk, OSPF now calculates the correct value for the
oversubscription factor.

SMDS Upgrades

The problem whereby upgrading the last switch in your network to versi
on
4.2.3 from a release version lower than 4.2.0 results in SMDS paths to all
switches being lost, has been corrected.

Low Memory on IOP

(C97
-

The problem whereby low memory on IOPs caused the trunk state in OSPF
to trash limits for adding new PVC
s has been corrected.

LMI Asynch Delay

Problems with LMI asynch delay and full status updates on NNI ports
causing circuits to delay in coming up has been resolved.

OPTimum Trunk on

You can now configure and OPTim
um Trunk on an unchannelized E1 NNI
port.

Changing CP Capability

(C97

Changing the CP capability no longer causes both CPs to go down at the
same time.

ISDN Channel Alignment

There are no longer any problems with ISDN channel alignment

above
TS16 (Australian ISDN).

The problem with redundant CP 30/40/50 cards has been fixed.

Previously, in a redundant configuration (CP 30/40/50 with CP 30/40/50),
the IOP cards would reboot when you inserted the second CP 30/40/50

A trap now appears to indicate a successful boot up of a standby CP card.

Redundant CP cards

The following redundant CP card problems were resolved:



The problem of CP Basic and CP+ redundant pair combinations

resulting in CP crashes or switchovers has been corrected.



The standby CP has been modified to ignore information directed to it
by the console UART. Previously the standby CP would attempt to
process data coming in on the console UART, resulting in sympt
oms
such as the standby CP reporting 100% CPU utilization, or being shot
by the active CP.



Warmbooting a redundant CP no longer causes the CPs to switchover.

CP problems during trunk
initialization

In previous releases, trunk initialization on a switch wo
uld result in
intermittent memory corruption on the CP. This corruption could cause CP
crashes, background diagnostic errors, or loss of CP PRAM. This problem
