Chapter 1 Introduction
1.1. Scope
These release notes summarize operational requirements and issues for the following
Router 3000 and Router 5000 modules and software release V1.10. Read these release
notes before installing your router.
Table 1 Router Model Numbers
Description 3C Number
3Com Router 3012 3C13612
3Com Router 3013 3C13613
3Com Router 3016 3C13616
3Com Router 5009 3C13700
3Com Router 5231 3C13750
3Com Router 5640 3C13754
3Com Router 5680 3C13758
1.2. Cable Connections
3Com recommends that you power off the router before connecting any cable.
Do not connect and disconnect synchronous or asynchronous serial WAN cables, console
cables, Ethernet cables, ISDN BRI cables, and 4-port serial WAN adapters while power to the
router is on. Connnecting cables while power to the router is on can crash the router or
damage the serial port.
1.3. Online Resources
3Com routers contain a software agent that can be upgraded using the command line
interface. The software agent that is initially provided with the routers does not fully support
GRE, L2TP, IPSec, or SNMPv3.
To download a software agent that adds full support for these features, visit the 3Com support
website at
http://support.3com.com to register your product. Note that this download agent
contains encryption capabilities that are restricted to certain users and countries so approval for
these downloads can take up to 48 hours.
To upgrade to future software agents that contain additional features, you must purchase a
service contract. Details are provided on the Service and Warranty pages of the 3Com support
website
http://support.3com.com .
See the Router 3000 Installation Guide or Router 5000 Installation Guide for software
download instructions.

Chapter 2 Release Notes for
the Router 3000 and Router
5000 Series V1.10
This chapter offers updates on Router 3000 and Router 5000 features in the following areas:
System Access Routing Protocol Dial-Up
System Management Multicast Protocol
Interface Management Security
Link Layer Protocol VPN
Network Protocol QoS
2.1. System Access
Symptom Solution
A user, logging in as an operator, can see
administrator passwords.
Use encrypted passwords instead of simple
passwords.
2.2. System Management
Symptom Solution
If you add or remove a module, the
configuration may be altered.
Save the configuration file and edit it with the
new interface numbers so that the file
corresponds with the new physical
configuration.
The router reboots if an invalid agent software
file is used to upgrade the device.
Insure that the correct agent file has been used
before writing to flash memory.
Use Xmodem or TFTP to upgrade and recover
the device.
RMON MIB tables can be created on an
Ethernet interface on which RMON is disabled,
but no data is collected.
Enable RMON on interfaces being used for
monitoring.
RMON history bucket allocation fails if more
than 50 buckets are requested.
Insure no more than 50 buckets are requested
when creating an RMON history table.
RMON Matrix DS table has src and dst
addresses reversed.
Use the SD table instead.
Routers are not recognized by Network
Management applications, such as 3Com
Network Supervisor, unless SNMP V1 is
enabled.
Enable SNMP V1 on the device, as described
in the Installation Guide, and then discover the
network using Network Supervisor.
RELEASE NOTES FOR THE ROUTER 3000 AND ROUTER 5000 SERIES
V1.10
2.3. Interface Management
Symptom Solution
Interface changes may require a reset of the
interface for changes to take effect.
If you make a configuration change to an
interface, reset the interface.
The error message for deleting a PRI is
incorrect.
Use the undo pri-set command instead.
Dialer interfaces do not support IP
Unnumbered.
Assign an IP address to dialer interfaces.
When initially configuring a virtual template, a
reboot of the router may be necessary.
Save the configuration and reboot the router.
2.4. Link Layer Protocol
Symptom Solution
LMI Encapsulation type has been renamed. If the frame relay peer is set to LMI, set the
Local Interface to Non-Standard.
Router 3000 series routers do not auto-
negotiate with the 3Com SSII Dual Speed Hub
500.
Adjust the speed and duplex manually on both
devices so they match. Disable auto mode.
Routers only support switch type dss1 BRI S/T
(European ISDN).
Routers only support switch type dss1 in this
release.
2.5. Network Protocol
Symptom Solution
IGMP query timer defaults to 60. Set the query timer, manually, to 125.
Naming inconsistency with interface and IPX
static routes.
When configuring a static route for a network
that begins with an alpha character, preface
the network with 0x.
IPX RIP entries are not aged-out at the user-
defined interval.
The IPX RIP table entries are removed from
the table if updates for those entries are not
received within the default interval of 180
seconds. This value is based upon a default
RIP update timer of 60 seconds and a default
multiplier of 3.
IPX SAP services’ timer and multiplier value
configurations are ignored.
IPX SAP updates are received once a minute
regardless of configuration settings.
MTU size cannot be dynamically changed from
the default of 1500.
If making a change to the MTU size, reboot the
router afterwards.
When you configure NAT outbound on an
interface, that interface is not immune to the
NAT translation.
Deny the NAT outbound interface address with
an Access List.
RTP header compression is not fully supported
in this release.
RTP header compression is not fully supported
in this release.
Load balancing does not work through
recursive lookup.
Use MLPPP or OSPF to support load
balancing.
IPX WAN encapsulation is configurable over
HDLC.
IPX WAN encapsulation is configurable over
HDLC.

RELEASE NOTES FOR THE ROUTER 3000 AND ROUTER 5000 SERIES
V1.10
2.6. Routing Protocol
Symptom Solution
Any route policy that uses ACLs defaults to
permit all.
Add an explicit deny all or permit all rule at
the end of all ACL statements.
The OSPF command, abr-summary not
advertise is not working correctly.
The abr-summary not advertise command
does not filter the initial route in a summary
update. For example, 128.213.64.0/19 filters
the routes 128.213.65.0 to 128.213.95.0 but
does not filter 128.213.64.0.
If necessary, configure an ACL to filter the
route.
Changing the OSPF Area on an interface will
delete the OSPF configuration on that
interface.
Save the OSPF configuration file before the
change.
Changes to an access list are not applied until
the route policy is reapplied.
Reapply the route policy immediately after
making changes to the access list.
The display bgp route command only shows
one route even if multiple (backup) routes are
available.
The display only shows detail information for
the best route.
RIP MD5 Authentication types are ambiguous. For RIP MD5 Authentication, use the default
non-standard value. This is the most common.
Routing does not function correctly, in a virtual
template with multilink PPP and OSPF
configuration.
When using MP with OSPF, you must
configure OSPF peer ipaddress.
When using a serial DTE interface, the OSPF
cost may not be set correctly.
Set the OSPF cost for the DTE manually.
BGP places all internal peers into one peer
group by default,
To configure different policies for one peer,
place that peer in a separate peer group and
define policies for that peer group.
The router supports only 15,000 entries.
Receiving over 15,000 BGP routes may cause
the router to hang.
Arrange with the local ISP to filter routes before
updates can reach the router.
With Routing Policies, matching next-hop
based on IP prefix list does not actually match
the next BGP hop.
Use ACL instead of prefix-list.
Toggling route-reflection with a connection
established causes the router to reboot.
Shut down the interface before toggling route-
reflection.
A route policy specified in a peer group does
not take effect after a reboot,
Reenter the route-policy after the router has
returned to service.
Poison Reverse is not supported in this
release.
Poison Reverse is not supported in this
release.
2.7. Multicast Protocol
Symptom Solution
The router does not support IP multicast
forwarding without the multicast routing
protocol.
Keep PIM-SM or PIM-DM enabled on the
interface to insure multicast runs correctly.
Enabling ip unnumbered on a PIM-SM
interface disables PIM-SM routing.
Do not configure ip unnumbered on a PIM-SM
interface.

RELEASE NOTES FOR THE ROUTER 3000 AND ROUTER 5000 SERIES
V1.10
2.8. Security
Symptom Solution
ACL match counts are not logged. ACL match counting is only supported with the
firewall feature.
If you are using automatic matching order with
ACLs, a rule that is similar to an existing rule,
even if they have different qualifiers, is not
added as a separate rule.
Remove the existing rule before applying the
new rule.
IPSec in transport mode will transmit transit
traffic with no security headers. IPSec in
transport mode is designed for direct
communications between two peers running
IPSec.
Use Tunnel mode if you are configuring the
router to be an IPSec gateway.
IPSec nesting is not supported in this release. IPSec nesting is not supported in this release.
The Encryption card status message,
Byte
Order: Not consistent with host
,
can be misleading.
Disregard this status message.
Only one security association is used for each
ACL-incompatible with per-rule implementation.
Create one separate ACL for each permit
statement in the third-party access list.
2.9. VPN
Symptom Solution
The basic version of this release does not
support GRE or L2TP.
Use the extended version of this release for
GRE and L2TP tunneling support.
2.10. QoS
Symptom Solution
NBX Layer 2 traffic cannot be classified for
QoS.
Use Layer 3 prioritization.
2.11. Dial-Up
Symptom Solution
The ppp chap user command is not supported
in dialer interfaces.
When using Resource DCC and using chap
authentication, ppp chap user should be
configured only on the router that is dialing out.
