Upgrading to Version 15.4.2.0
To upgrade BayRS to Version 15.4.2.0, see Upgrading Routers to BayRS Version
15.xx, in your upgrade package. In addition, read the following sections.
Upgrading ATM Configurations
If you are upgrading fr om a BayRS v ersi on earl ier t han 12.20 and you de f in ed log
event traps for asynchron ous transfe r mode (ATM), ATM signaling, or ATM LAN
emulation, you must redefine these traps.
The ATM, ATM signaling, and ATM LAN emulation log event messages changed
in BayRS Version 12.20. The ATM_SIG entity (entity #95) no longer exists as a
separate entity. We have combined the ATM_SIG entity with the ATM entity
(entity #78). Combining and reorganizing these entiti es resulted in changes to the
ATM log event mess age numbers. We added new log e v ents to the ATM_LE entity
(entity #100), result ing in log event message number changes for LAN emulation
as well.
You can view the new and modified ATM log event messages in the event
database on the BayRS Online Library CD, or on the World Wide Web at this
URL:
http://www25.nortelnetworks.com/library/tpubs/events/
Cell Scrambling Default Changes for DS1/E1 and DS3/E3
For pre-15.x ver sions of BayRS, the default f or the cell scra mbling param eter is
set to On for DS1/E1 and DS3/E3 modules. However, the default for this
parameter has been changed to Off for all BayRS 15.x versions. If you are
upgrading from a pre-15.x v ersion (fo r example, 14.2 0) of BayRS you will need to
set this parameter to On to activate cell scrambling.
See Configuring ATM Services for additional information for setting this
parameter using the BCC or Site Manager.
2 308663-15.4.2.0 Rev 00
Upgrading DVMRP Configurations
In BayRS Version 15.1.0.0 and later, the default values for two DVMRP timer
parameters have been changed to conform with the latest RFC for DVMRP
(draft-ietf-admire- dvmrp-v3-10). Table 1
new default values.
Table 1. DVMRP Parameter Defaults Changed
Parameter Name Default Value (in seconds)
Site Manager BCC
Garbage Timeout unconfirmed-route-timeout 340 260
Route Expiration Timeout route-expiration-timeout 200 140
DVMRP timers must be the same throughout the network. Therefore, if your
DVMRP network changes—for example, if you add a DVMRP router running
Version 15.1.0.0 (or later) to the network, or if you create a Version 15.1.0.0 (or
later) configuration file that contains DVMRP— make sure that the values for the
timer parameters match the ones already configured for the network as a whole.

Upgrading FireWall-1 Configurations
Complete the following steps only if you are upgrading FireWall-1* from a
BayRS version earlier than 13.20. If you are running Firewall-1 from BayRS
Version 13.20 or later, you do not have to complete these steps during your
upgrade to BayRS Version 15.4.2.0.
Note: Firewall-1 is not supported on the Passport* 2430 and Passport 5430
platforms.
1. Familiarize yourself with the Bay Command Console (BCC*).
Starting with BayRS Version 13.20, FireWall-1 no longer supports Site
Manager as a configuration tool. You must use the BCC to manage and
configure FireWall-1. For basic information about using the BCC, see Using
the Bay Command Console (BCC).
308663-15.4.2.0 Rev 00 3
Release Notes for BayRS Version 15.4.2.0
2. Make sure that you will not lose acc ess to your router.
When you upgrade to BayRS Version 15.4.2.0, once you boo t your rou ter, the
Version 15.4.2.0 software invokes the default Fi reWall-1 secu ri ty pol i c y. This
default security policy drops all attempts at communication with the router.
If you manage a router at a remot e loca tion, y ou will no longe r be abl e to g ain
access to the router through the WAN connection. Before you upgrade, make
sure that you can gain access to the router by dialing in through the console
port, or that there is someone at the remote location who can configure the
router.
3. Reboot the router with BayRS Version 15.4.2.0, using an existing
configurat ion file.
4. Use the BCC to reenable FireWall-1 on each IP interface.
To reenable FireWall-1 on each IP interface, use the BCC to navigate to the
prompt for the slot/connector on which you have configured the IP interface
(for example,
box; eth 2/2). Then enter:
ip address
ip_address
address_mask
<ip_address>
mask
<address_mask>
is the IP address you have assi gned to the interface.
is the mask associated with the IP address.
The prompt for the IP interface appears.
For example, the following command invokes the prompt for IP interface
2.2.2.2/255.0.0.0 (which h as b een c onfigured on Ethernet slot 2, connector 2) :
ethernet/2/2# ip address 2.2.2.2 mask 255.0.0.0
ip/2.2.2.2/255.0.0.0#
At the promp t for the IP interface, enter the following command to reenable
FireWall-1:
firewall
The firewall prompt appears.
For example, the following command reenables FireWall-1 on the IP interface
2.2.2.2/255.0.0.0:
ip/2.2.2.2/255.0.0.0# firewall
firewall/2.2.2.2#
5. To use FireWall-1 on more than 32 circuits, set the policy index number
for each IP interface.
4 308663-15.4.2.0 Rev 00
Release Notes for BayRS Version 15.4.2.0
The policy index allows multiple circuits to share the same instance of
FireWall-1. You can have up to 32 instances of FireWall-1, with many circuits
making up each FireWall-1 instance. All cir cuits in a grouping must share the
same security policy.
By default, the policy index for a circuit is equal to the circuit number. If you
are using FireWall-1 on fewer than 33 circuits, you do not have to use policy
indexes.
If you are using FireWall-1 on more than 32 circuit s, gr oup ci rc uits that share
the same security policy. Then, set the policy index on each circuit in a group
to the same value.
For examp le, supp ose you w ant to use FireWall-1 on 40 circu its. Th e f irs t f i ve
circuits share one securi ty pol ic y; the ne xt 35 sha re a di f fer ent s ecur ity p olic y.
Using the BCC, assign p olic y i nde x 1 to the first five circu its and p oli c y inde x
2 to the next 35 circuits. You then have a total of 40 firewall circuits on the
router, with two policy index values and two security policies.
Note: If you do not use policy index values and you configure more than 32
circuits on the route r, all IP forwarding is d isabl ed o n circ uits afte r the 32nd. If
you use policy index values, but configure more than 32 policy index
groupings, all circuits assigned policy indexes after the 32nd will have all IP
forwarding disabled. The router logs warning messages that can help you
determine whether you have any circuits on which all IP forwarding is
disabled.
The Check Point log viewer treats circuits that share a policy index as one
circuit.
If you are running FireWall-1 on more than 32 circuits and you therefore nee d
to set the policy index value, use the BCC to navigate to the firewall prompt,
as described in step 4. Then enter:
policy-index
is the index value, from 1 to 1023.
value
<value>
For example, the following command sets the policy index to 1:
firewall/2.2.2.2# policy-index 1
firewall/2.2.2.2#
6. Save the configuration file and reboot the router.
308663-15.4.2.0 Rev 00 5
Release Notes for BayRS Version 15.4.2.0
7. Reinstall the security policy.
Since you previously defined a security policy (using the earlier version of
BaySecure FireWall-1), you do not nee d to def ine it ag ain. Ho we v er , y ou must
reinstall it in on the router. For com plete instructions on how to install the
security policy, see your Check Point FireWall-1 documentation.
If you want to install different security policies for different policy indexes,
use the Check Point FireW all-1 command line interface to enter the following
command:
fw load ../conf/

For example, the following command specifies that the system install the
security polic y in t he configuration file drop_ftp on policy index number 1 on
the router named asn1:
fw load ../conf/drop_ftp pol1@asn1
Upgrading IP Route Filters
If you have configured IP route filters and then disabled those filters (rather than
deleted them), when you upgrade to Version 15.4.2.0 from a version earlier than
14.00, the filters will be re-enabled. You must disable the filters again after the
upgrade is complete. If you do not want to use the filters, you might want to
consider deleting them before you upgrade to Version 15.4.2.0.
Upgrading L2TP Configurations
If you have a BayRS Version 12.10 configuration file that includes L2TP
operating on a router using BayRS Version 15.4.2.0, the router automatically
upgrades the assigned user network addresses to L2TP IP interface addresses.
L2TP IP interface addresse s are internal to the router. When communicating with
the remote user, the router associates the user’s IP address with an L2TP IP
interface address that you configure.

The user networ k address es assig ned to Versi on 12.10 app ly to th e enti re rout er. In
Version 15.4.2.0, each slot has a unique L2TP IP address. Consequently, if the
number of configured L2TP slots is greater than the number of configured
assigned user network addresses, the router will not be able to upgrade every slot
from a Version 12.10 configuration to a Version 15.4.2.0 configuration. For slots
that exceed the number of assigned user network addresses, you must manually
configure L2TP IP interface addresses. To do this, delete L2TP from the slot, and
then configure a new L2TP interface. Each slot must have L2TP IP interface
addresses.
If the number of configured L2TP slots is less than or equal to the number of
configured assigned user network addresses, the router automatically converts all
assigned user network addresses to L2TP IP addresses.
Upgrading OSPF Configurations
When you upgrade BayRS from releases earlier than Version 12.20, there must
not be an open shortest path first maximum transmission unit (OSPF MTU)
interface mismatch. If a mismatch exists, adjacencies will not form between
upgraded routers. All the OSPF routers forming adjacencies on a segment
(broadcast, point-to-point [PPP], Point-to-Multipoint, or nonbroadcast
multi-access [NBMA]) should have the same OSPF MTU size. You configure the
OSPF MTU size through the MTU Siz e paramete r in the OSPF Interf aces windo w
in Site Manager.
Release Notes for BayRS Version 15.4.2.0
BayRS Versions 14.00 and later comply wit h RFC 2328, which r equires the OSPF
MTU size feature.
Upgrading Static Forwarding Policy Filters
Internet Group Management Protocol (IGMP) static forwarding policy filters that
you created in versions earlier than Site Manager Version 7.20 will not work
correctly using Site Manager Version 7.20 or later. To use these IGMP static
forwarding poli cy f ilte rs, you must re-cr eate th em. F or inf ormati on about creati ng
IGMP static forwarding policy filters, see Configuring IP Multicasting and
Multimedia Services.

SNMP CERT Advisory
BayRS Version 15.3 a nd later inclu de fixes for SNMP CERT* Adviso ry
CA-2002-03 for all suppo rt ed BayRS router platforms. BayRS is not impacted by
the trap attacks identified in the CERT Advisory but is impacted due to SNMP v1
request att acks. Site Ma nager Versi on 15.3 and later also include fixes for SNMP
CERT Advisory CA-2002-03. Site Manager provisioning is not impacted as a
result of the CER T Adv isory. Site Manager Tr ap Monitor is impac ted and the f ixes
are provided in the Site Manager Version 15.3 and later.
Known Anomaly
The following anomaly exists for BayRS 15.4.2.0. Nortel Networks aims to
resolve these anomalies in the near future.
NAT
Anomaly: Bidirectional NAT is not functional if you use a Passport 2430 as the
NAT router.
ID: Q00064004-04
Description: The Passport 2430 router is not supported as a NAT router for
bidirectional NAT.
Workaround: For BayRS Version 14.20 or later, do not use the Passport 2430
router as a NAT router with bidirectional NAT configured.
BCC Guidelines
The BCC is a command-line interface for configuring Nortel Networks devices.
Before using the BCC, see the following guidelines for using the software and the
platforms, protocols, interfaces, and hardware modules that the BCC supports.

BCC and BayRS Compatibility
Starting with BayRS Version 14.00, the BCC software version number matches
that of BayRS. For e x ampl e, t he version for both the BCC and BayRS is 15.4.2.0.
We have made this change to help y ou al ign versions of the BCC with versions of
BayRS.
Setting the Impedance Value for the Passport 2430
The Passport 2430 c an acco mmodate ei ther BNC (req uires 75 ohm i mpedan ce) or
RJ45 (requires 120 ohm impedance) connectors. You can use the BCC to set the
impedance-value attribute to either 75 ohms or 120 ohms.
To set the impedance value on the FE1 interface, go to the FE1 prompt (for
example,
box; fe1) and enter:
impedance-value
value
is one of the following:
rj45-120-ohms (default)
bnc-75-ohms
<value>
For example, the following command sets the impedance value to 75 ohms for
this interfa ce on the router:
fe1/1/1# impedance-value bnc-75-ohms
fe1/1/1#
Creating FTP from the BCC
From the BCC, if you create FTP on the router, then delete it and re-create it, the
BCC faults. In this case, you must restart the BCC and create FTP on the router
again.
Deleting Interfaces with the BCC
Before using the BCC to dele te an interface, make sure that you did not use Site
Manager to configure the interface with a protocol that the BCC does not
recognize. If you did, use Site Manager to delete the interface.

Memory Requirements
To use the BCC, each slot on the router must have:
• 16 MB of dynamic RAM (DRAM)
• 2 MB of free memory available when you start the BCC
If you try to start the BCC with insufficient DRAM or free memory on a slot, the
BCC returns the following message. In this case, you must use Site Manager
instead of the BCC to configure the router.
**Error** Unable to load bcc command from file system.
Loadable Module: bcc.exe
Platforms Supported
The BCC runs on AN*, ANH, ARN, ASN, Pass port 2430, Passport 5430, System
