This release note describes the features and caveats for Cisco 700 software Release 4.2(3) and earlier. For complete documentation for Cisco 700 software, refer to the Cisco 700 Series Command Reference.
This document has the following sections:
Cisco 700 series router software Release 4.2(3) supports the following routers:
| Cisco 760 Series | Cisco 770 Series | CPA760 Series |
|---|---|---|
Cisco 761 | Cisco 771 | CPA761 |
Cisco 762 | Cisco 772 | CPA762 |
Cisco 765 | Cisco 775 | CPA765 |
Cisco 766 | Cisco 776 | CPA766 |
The following documentation is provided with your Cisco 700 series router:
This section provides information that was not included in the current documentation and is not available elsewhere. The information will be included in the next revision of the documentation.
The Cisco 700 series router attempts to establish a connection with the remote host whenever interesting traffic is queued to be sent over a WAN connection. When bridging is off, the router attempts to connect to the remote device when IP traffic is queued. When bridging is on (default), the router attempts to connect when IP traffic and all nonrouted traffic is queued.
It is recommended that bridging be set to off in a WAN profile to reduce the amount of interesting traffic, and therefore, the number of attempts made to establish a connection. If the remote connection goes down, the router continuously attempts to bring up the line. In some environments (most commonly Windows NT using only Netbios), this causes the line to dial continuously. Depending on your configuration and how your connection is billed, turning bridging off in the WAN profile might reduce your costs.
For example, in the configuration titled "Routing IP On Demand," which begins on page 3-16 of the Cisco 700 Series Router Installation Guide (DOC-782412=), you should enter the command set bridge off near Step 11. The exact sequence of this command in relation to the other commands is not critical, as long as it is done in the central902 profile.
The set clicallback command was left out of early online versions and the paper copy of the Cisco 700 Series Router Command Reference. The command was replaced in the online version and is available on Cisco Connection Online (CCO), and the August, 1998, and later Documentation CDs.
The Cisco 700 series router software Release 4.2(3) provides the following enhancements:
In the IR image for software Release 4.2(3), the number of users allowed is increased to 30.
When receiving an incoming data call, some Net3 switch types require that the router receiving the data send a Call Alerting Q.931 message back to the ISDN network. Prior to software Release 4.2(3), the Cisco 700 series router sent Call Alerting messages to the network only for incoming voice calls, not for incoming data calls. In software Release 4.2(3), the Cisco 700 series router returns a Call Alerting Q.931 message to the ISDN network when data calls originate from NET3 switch types. For all other switch types, the Cisco 700 series router sends Call Alerting messages only for incoming voice calls.
Cisco IOS software Release 11.3(4)T supports multipoint operation in X25/D communications with a Cisco 700 series router running software Release 4.2(3). This includes support for X25/D Policy Routing, Priority queueing, and AO/DI.
The X.121 address can be added to packets sent over the D channel using the set x25d x121host x121address command. To view the X.121 address set in the router, use the show x25d x121host command.
show X25d X121host
System or profile mode
This command shows the X.121host address, the value of the x121 address entered using the command set x25d x121host command.
The following example displays the x121host address:
700> show x25d x121host
X25D X121HOST 14081763269
set x25d x121host
This section provides the latest information about Cisco 700 series router software Release 4.2(3) limitations. Each item includes the Cisco DDTS tracking number, if applicable.
During the upload of a configuration over ISDN the line, the DEMAND 1 DURATION statement is missed. This has been resolved in software Release 4.2(3). (CSCdj80519)
In the 1tr6 image, if you are connected on a voice call and flash, the message "Warning: Illegal dereference" displays and the router might reboot. This has been resolved in software Release 4.2(3). (CSCdk03329)
The Cisco 700 series router Telnet server does not give up by timeout. The router calls the Telnet client every 2 minutes and does not stop. The condition is created as follows:
This has been resolved in software Release 4.2(3). (CSCdk11798)
AO/DI is available only on one connection. Even if it is enabled on multiple profiles, only one profile at a time can use it. (no number available)
When TAS mode is on, the Cisco 700 series router continuously attempts to authenticate after a failed login. For example, a user launches a Web browser but does not enter a login ID. The connection to the CiscoSecure Authentication Agent times out (as it should); however, the router continues to retry the connection. During the subsequent retries, the router sends its own authentication information, not the authentication information of the user. This results in sessions going up and down continuously. This has been resolved in software Release 4.2(3). (CSCdk24138)
This section provides the latest information about Cisco 700 series router software Release 4.2(3) caveats. Each item includes the Cisco DDTS tracking number, if applicable.
Windows NT clients fail to browse for a Windows NT server as a result of the following condition:
This has been resolved in software Release 4.2(3). The Cisco 700 series router checks the IPX destination network field in the NetBIOS packet. If the network number field is not zero, the router changes the field to zero and forwards the packet to the LAN. (CSCdk20359)
RIP updates keep the ISDN link up if the idle timeout is greater than the RIP timer value, even if the RIP option is linkup. However, it does not cause the link to come up by itself. To correct the problem, use a filter for RIP traffic with the ignore option in the WAN profile. (no number available)
The system password is echoed over the ISDN connection the first time the connection is established. However, it is not echoed in subsequent connections. (CSCdj81519)
The upload command does not include the set ip route destination 0.0.0 propagate off conv1 command in the configuration if a default route was entered in the user-defined profile before the connection was made. This occurs when the router connects to an Internet service provider and obtains an IP address through IP control protocol (IPCP) negotiation. This has been resolved in software Release 4.2(3). (no number available)
A router repeatedly receives voice calls when both B channels are occupied with data calls intermittently loses one of the B channels. This has been resolved in software Release 4.2(3). (CSCdj68840)
When you ping from the Cisco 700 series router console using X25/D policy routing, under normal circumstances, the source address is the Ethernet interface address. However, if there is an entry in the routing table which matches the address in the policy table, the source address is the WAN profile address. (CSCdk26873)
This section describes the applications supported by the Cisco 700 series router software Release 4.2(3).
The CiscoSecure Authentication Agent (available for Windows 95 and Windows NT 4.0) application simplifies the use of token authentication over ISDN. There are two authentication modes: single authentication and double authentication.
The Cisco 700 series router operates in single authentication mode when Token Authentication Support (TAS) is enabled. CiscoSecure Authentication Agent is available on the World Wide Web (WWW). See the "Cisco Connection Online" section in this document for more information.
Cisco 700 series router software Release 4.0(1) and higher supports Cisco 700 Fast Step. Cisco 700 Fast Step simplifies the setup, configuration, and monitoring of Cisco 700 series routers.
Cisco 700 Fast Step runs on Microsoft Windows 95 and Windows NT 4.0 systems. It is provided with your router on the Cisco Fast Step CD-ROM. The application is also available on Cisco Connection Online. See the "Cisco Connection Online" section in this document for more information.
This section describes the process for saving the current configuration and updating the router software image. The default image for Cisco 761, Cisco 765, Cisco 771, and Cisco 775 routers is NET3, IR. The default image for all other Cisco 700 series routers is US.
Images for software Release 4.0(1) and higher require 1.5 MB of dynamic RAM (DRAM). If you do not have enough DRAM to support the software, the router does not boot. Refer to the "National ISDN Capability Packages" section for instructions on checking the amount of DRAM. Instructions for increasing the amount of DRAM are in the Cisco 700 Series Router Installation Guide.
X.25 images require 1.5 MB of DRAM and 1 MB of Flash memory. If you do not have enough Flash memory to run X.25 images, the router must be replaced with a Cisco 700M series router. The label on the bottom of the router identifies an M-series router. You can display the amount of Flash memory by using the version command. Refer to the Cisco 700 Series Router Command Reference for information about this command.
The following example saves the configuration to a file by using Terminal for Windows, a common terminal emulation software program:
Step 1 When the terminal emulation program is running, enter the upload command at the command-line prompt, but do not press Return after you enter the command:
Step 2 From the Transfer menu, select Receive Text File.
Step 3 In the Receive Text dialog box, specify a filename to save the configuration in, and select the directory where you want to save the file.
Step 4 Click OK.
Step 5 Return to the terminal emulation program, and press Return to execute the command. The configuration is saved to the file specified in Step 3.
Step 6 Click Stop when the configuration has finished uploading. You are ready to download the software.
Select the image (filename) for your router. Table 1, Table 2, and Table 3 list the filename and memory required for each image. Images named C760 are for use with both Cisco 760 and Cisco 770 series routers.
