This release note describes the features and caveats for Cisco 700 series router software Release 4.4.2 and earlier. For complete software documentation for Cisco 700 series router software, refer to the Cisco 700 Series Router Command Reference.
This document has the following sections:
The new features of this release include: NetBios filtering, show packets command, Tpad Parity mask, comma character support, and PAT enhancements.
Cisco 700 series router software Release 4.4.2 supports the following routers:
| Cisco 760 Series | Cisco 770 Series |
|---|---|
Cisco 761M | Cisco 775M |
Cisco 762M | Cisco 776M |
The default software image for Cisco 761M and 775M model routers is Cisco 700 Internet Ready IP/X.25 (Europe) software for Euro ISDN (NET/3) switch types. The default software image for Cisco 762M and 776M model routers is Cisco 700 Internet Ready IP/X.25 (US) software for U.S. switch types.
Images for software Release 4.0(1) and higher require 1.5 MB of dynamic RAM (DRAM) and 0.5 MB of Flash memory. If you do not have enough DRAM to support the software, the router does not boot. See the "ISDN Support Services" 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.
This section describes how to save the current configuration and update the router software image.
The following example saves the configuration to a file by using Hyperterminal for Windows, a common terminal-emulation software program:
Host> Upload
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 as, 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.
Table 1 list the filename and memory required. The image is for use with both Cisco 760 and Cisco 770 series routers. 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 M-series router. The label on the bottom of the router identifies the device as 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 loads the configuration by using Hyperterminal for Windows, a common terminal-emulation software program:
Step 2 Set flow control to Line at a Time, and set Delay Between Lines from 0.5 to 1 second.
Step 3 Click OK.
Step 4 From the Transfer menu, select Send Text File.
Step 5 Select the file to be loaded, such as the one you saved in Step 2 in the "Saving a Configuration" section.
Step 6 Click OK. The parameters are transferred to your router.
Step 7 If errors occur during the transfer, enter the set default command, increase the delay between lines, and repeat the procedure for loading the configuration, beginning with Step 1.
This section describes the applications supported by the Cisco 700 series router software Release 4.4.2.
The CiscoSecure Authentication Agent application (available for Windows 95 and Windows NT 4.0) simplifies the use of token authentication over ISDN. There are two modes: single authentication and double authentication.
The Cisco 700 series router operates in single authentication mode when Token Authentication Support (TAS) is enabled. The CiscoSecure Authentication Agent application is available on the Cisco Web site. See the "Cisco Connection Online" section in this document for more information.
Cisco 700 series router software Release 4.0(1) and higher supports the Cisco 700 Fast Step software. Cisco 700 Fast Step software simplifies the setup, configuration, and monitoring of Cisco 700 series routers.
Cisco 700 Fast Step software runs on Microsoft Windows 95, Windows 98, and Windows NT 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.
With RVS-COM Lite software version 1.6 and higher, you can use your ISDN router with a PC for general ISDN communications including fax transmission, file transfer, and telephony. The router can be used from several different client-PCs at the same time: for example; one PC sending a fax while a second PC is transferring files.
RVS-COM Lite is a general ISDN-CAPI 2.0 driver for Windows 95/98/NT, which can be used by different ISDN communication programs (such as AVM Fritz, Symantec WinFax, T-Online, or RVS-COM) to access ISDN by using the router. The RVS-COM Lite software support is available only for NET3 images (X.25 and non-X.25) and must be installed on each PC.
 |
Note RVS-COM does not detect when the router is turned on or off. The RVS CommCenter must be restarted by the user to accept incoming calls after router reboot. |
The installation instructions for your RVS-COM software are provided in the readme file on the RVS-COM CD. The following sections provide instructions for using RVS-COM with America Online (AOL), T-Online, and CompuServe in Germany.
Step 2 Select ISDN RVS-CommPort>1.20 Emulation X.75 64000.
Step 3 Enter the COM port for the RVS-CommCenter (COM3 or COM4).
Step 4 Enter the phone number 01914 (Germany).
Step 2 Select modem ELSA MicroLink ISDN/TLpro.
Step 3 Click Erweitert.
Step 4 Enter the COM port for the RVS-CommCenter (COM3 or COM4).
Step 5 Select Datenaustausch über Windows-COM (not INT14).
Step 2 Choose Dial-Up Networking.
Step 3 Select the RVS ISDN X.75 transparent modem from the Phonebook entry to dial list.
The enhancements offered by Cisco 700 series router software Release 4.4.2 are described in this section.
The comma (,) character is supported in the system name and user name. (CSCdp35177)
For example, the following statement is valid:
scr1> set system scr1,scr5
The netbios filter command enables or disables NetBIOS User Datagram Protocol (UDP) and Transaction Control Protocol (TCP) packet filters.
SEt NETbios FIlter ON | OFf Command Mode
Profile mode
Usage Guidelines
This command adds the following IP filters to the filter list:
SET IP FILTER UDP OUT DEST 0.0.0.0/0:137-139 IGNORE SET IP FILTER TCP OUT DEST 0.0.0.0/0:137 IGNORE SET IP FILTER UDP OUT DEST 0.0.0.0/0:53 IGNORE
The command affects only WAN profiles. By default, the command is on for all the WAN profiles, including the Standard profile.
NetBIOS spoofing and NetBIOS filtering are mutually exclusive. Turning on either sets the other to off.
The following example shows the response when NetBIOS spoofing is set to on:
test:Standard> set netbios name spoofing 100 Netbios filtering will be set to off test> test:Standard> set netbios filter on Spoofing will be set to off
The following example uses the show command to display the status of NetBIOS filtering:
test:Standard> show ip filter all IP Type Filter Profile ID Dir Type Action Addresses ---------------------------------------------------------- Standard 1 OUT UDP IGNORE DST 0.0.0.0/0:137-139 Standard 2 OUT TCP IGNORE DST 0.0.0.0/0:137 Standard 3 OUT UDP IGNORE DST 0.0.0.0/0:53
The reset ip filter all command does not remove the filters created by the netbios filter command. If you want to remove individual NetBIOS filters, use the reset ip filter filterid command. If you want to remove all the NetBIOS filters, use the set netbios filter off command. If all the NetBIOS filters are removed by using the reset ip filter filterid command, the netbios filter command is set to off.
The following example uses the show command to display the status of the NetBIOS filters when the filters are set to on:
test:new> show ip filter all IP Type Filter Profile ID Dir Type Action Addresses ---------------------------------------------------------- new 1 OUT UDP IGNORE DST 0.0.0.0/0:137-139 new 2 OUT TCP IGNORE DST 0.0.0.0/0:137 new 3 OUT UDP IGNORE DST 0.0.0.0/0:53 new 4 OUT IP BLOCK DST 192.168.1.0/24:250-270
The following example uses the show command to display the status of the NetBIOS filters after the reset ip filter command is used:
test:new> reset ip filter all test:new> show ip filter all IP Type Filter Profile ID Dir Type Action Addresses ---------------------------------------------------------- new 1 OUT UDP IGNORE DST 0.0.0.0/0:137-139 new 2 OUT TCP IGNORE DST 0.0.0.0/0:137 new 3 OUT UDP IGNORE DST 0.0.0.0/0:53
The following example uses the show command to display the status of the NetBIOS filters after the reset ip filter filterid command is used:
test:new> reset ip filter 3 test:new> show ip filter all IP Type Filter Profile ID Dir Type Action Addresses ---------------------------------------------------------- new 1 OUT UDP IGNORE DST 0.0.0.0/0:137-139 new 2 OUT TCP IGNORE DST 0.0.0.0/0:137
