Cisco 760 series and Cisco 770 series routers require 1.5 MB of DRAM to run Software Release 4.0(1) and higher. The Cisco 750 series routers require 1.0 MB of DRAM to run Software Release 4.0(1) and higher. If it is necessary to upgrade the DRAM in your router, see the Adding Additional Dynamic Random-Access Memory in Cisco 760 Series and CiscoPro CPA760 Series Routers publication for instructions.
The Cisco 770 series routers are shipped with 1.5 MB of DRAM. The Cisco 761, 762, 765, and 766 shipped after September 1996 contain 1.5 MB of DRAM. You do not need to add DRAM to these routers to install Software Release 4.0(1) and higher. The Cisco 765-US, 765-CA, 765-CE, 765-NL, 765-UK, 766-US, and 766-CA shipped before September 1996 contain 1 MB of DRAM. You must add at least 0.5 MB of DRAM to these router models to run Software Release 4.0(1) and higher.
If you are running Cisco 700 series router Software Release 3.2(4) or higher, use the show memstat command to find the total memory installed in your Cisco 700 series router.
The following shows a typical show memstat command output:
Host> show memstat ID 0: Size: 10 Avail: 8 Max: 8 Used: 1 Addr: 0x000DDBA8 ID 1: Size: 30 Avail: 69 Max: 80 Used: 16 Addr: 0x000DDDE2 ID 2: Size: 18 Avail: 35 Max: 35 Used: 0 Addr: 0x000DE5A8 ID 3: Size: 4 Avail: 36 Max: 36 Used: 0 Addr: 0x000DE850 ID 4: Size: 8 Avail: 220 Max: 220 Used: 1 Addr: 0x000DE908 ID 5: Size: 32 Avail: 223 Max: 400 Used: 180 Addr: 0x000E0650 ID 6: Size: 268 Avail: 20 Max: 20 Used: 1 Addr: 0x000E2238 ID 7: Size: 20 Avail: 80 Max: 80 Used: 2 Addr: 0x000E3764 ID 8: Size: 14 Avail: 124 Max: 200 Used: 76 Addr: 0x000E41E0 ID 9: Size: 54 Avail: 38 Max: 50 Used: 17 Addr: 0x000E629A ID 10: Size: 8 Avail: 1 Max: 2 Used: 1 Addr: 0x000EEC40 ID 11: Size: 54 Avail: 6 Max: 6 Used: 0 Addr: 0x000EEC70 ID 12: Size: 462 Avail: 4 Max: 4 Used: 0 Addr: 0x000EF588 ID 13: Size: 134 Avail: 2 Max: 2 Used: 0 Addr: 0x000F00C0 ID 14: Size: 68 Avail: 5 Max: 5 Used: 1 Addr: 0x000F0BB8 ID 15: Size: 96 Avail: 5 Max: 6 Used: 2 Addr: 0x000F0DA0 ID 16: Size: 112 Avail: 2 Max: 2 Used: 0 Addr: 0x000F0FA8 NVStore Used: 1203, Remaining 6989 (Deleted 77 + Unused 6912), Total 8192 RamStore Used: 0, Remaining 10000, Total 10000 RAM Size = 0x180000 Available memory=517088, Allocs=119, Frees=0 MbufAllocs=0x5, MbufFrees=0x5, MbufFail=0x0 IbufAllocs=0x0, IbufFrees=0x0, IbufFails=0x0 MlenMax=0xe0, MlenAvail=0xe0, MlenLow=0xdf, MlenAllocs=0x5, MlenFails=0x0 ZeroMax=0x0, ZeroAvail=0x0, ZeroLow=0x7fff, ZeroAllocs=0x0, ZeroFails=0x0
The RAM Size entry indicates the amount of DRAM installed, reported in hexadecimal. Table 5 lists the RAM size hexadecimal values reported by the show memstat command and the corresponding RAM size in megabytes.
| RAM Size (hex) | Memory |
|---|---|
| 0x100000 | 1 MB |
| 0x180000 | 1.5 MB |
| 0x200000 | 2 MB |
If you have less than 1.5 MB of DRAM in your Cisco 760 or 770 series router, Software Release 4.0(1) and higher will not run. (The Software Release 4.0(1) and higher image for the Cisco 750 series router runs in a 1 MB environment.) You can install another 0.5 MB of DRAM or you can reload Software Release 3.2(5).
To reload Software Release 3.2(5):
Step 1 Power up the router.
Step 2 As soon as the boot banner appears, press the ESC key several times.
Step 3 Read and follow the software load command instructions in the Cisco 700 Series Command Reference publication if you are loading from a floppy disk or the instructions in the CD booklet if you are loading from a CD.
Step 4 Read and follow the set default command instructions in the Cisco 700 Series Command Reference publication.
To upgrade to Software Release 4.0(1) and higher:
Step 1 Use the upload command to save the present configuration settings in the Cisco 700 series router to a file before you install the new software. (See the upload command in the Cisco 700 Series Command Reference publication for instructions.)
Step 2 Use the software load command to load the new software into the Cisco 700 series router. (See the software load command in the Cisco 700 Series Command Reference publication for instructions.)
The following steps provide an example of saving the configuration to a file using Terminal, a popular terminal emulation software program for Windows 3.1 and Windows 95:
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 it:
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.
The following steps provide an example of loading the new software using Terminal for Windows, a popular terminal emulation software program. If you experience errors when attempting to load the new software or your configuration, consider reloading
Step 1 Read and follow the software load command instructions in the Cisco 700 Series Command Reference publication if you are loading from a floppy disk or the instructions in the CD booklet if you are loading from a CD.
After the new software is loaded, you can load the saved configuration to the router.
Step 2 In the terminal emulation program, go to the Setting menu and select Text Transfer. The Text Transfer dialog box appears.
Step 3 Set flow control to Line at a Time and set Delay Between Lines to a value between 0.5 and 1 second.
Step 4 Click OK.
Step 5 From the Transfer menu, select Send Text File.
Step 6 Select the file you saved in Step 3 in the "Saving a Configuration" section.
Step 7 Click OK. The parameters are transferred to your router.
Step 8 If errors occur during the configuration transfer, enter the set default command, increase the delay between lines and repeat the procedure for loading new software and reloading the configuration, beginning with Step 1.
Enhancements of Software Release 4.0(1) for Software Release 4.0(1) and higher are described in this section.
The set ppp address negotiation command forces the dynamically negotiated IP address to be assigned to the user-defined profile. It is recommended that this feature be turned on when the network access server assigns the IP address, specifically, when the LAN profile is set up for IP routing. This command forces the negotiated IP address to be assigned to the standard or user-defined profile instead of the internal profile.
765> set ppp address negotiation local on
When this feature is on, the negotiated IP address is assigned to the user-defined profile. It also tells the software to use the IP address configured for this profile in the IP address negotiation.
When the feature is off, the negotiated IP address is manually assigned to the appropriate (internal or user-defined) profile by the system. The default setting is off.
The following example uses the IP address configured for this ISP profile for IP address negotiation. The new IP address (assigned by the remote router) is assigned to this ISP profile.
765> cd ISP 765:ISP> set ppp address negotiation local on
When a call is made and IP address negotitation has taken place, the router is assigned an IP address by the ISP. To verify the IP address, you can use the show ip config all command.
System level
set ip routing
set dhcp server
set ip pat
For 64K or 128K leased line connections, the previous versions of the 760/770 software required PAP/CHAP authentication when the connection is made. In Software Release 4.0(1) and higher, the authentication sequence is no longer required for leased line connections.
To eliminate the need for authentication, you can create a profile named leasedline (the name is not case-sensitive) or rename an existing profile. To create a new profile use the set user command:
765> set user leasedline
If a profile for a leased line is already defined with a different name, change to the profile and rename the profile to leasedline using the set profile command:
765>cd profilename 765:profilename>set profile user leasedline
If the leasedline profile is not present upon call connect, the router requires authentication to select the correct profile. If the call cannot be authenticated, the router defaults to the standard profile.
Within the leasedline profile, verify that PPP authentication is set to none (the default) using the show security command:
765>show security
The switch types that support this feature are PERM64 and PERM128.
Call Forwarding supplementary service (Cisco 760 and 770 series routers) has been added for this release for Sweden and Finland (NET3). Call Forwarding is implemented differently in the European countries. The version implemented here uses keypad procedures and is only partly ETSI-compliant.
The Call Forwarding types supported are as follows:
In all types of Call Forwarding, the user's ability to originate calls is unaffected by the Call Forwarding supplementary service.
The feature numbers for Call Forwarding are provided here for convenience, but they could be different in your area, depending upon the local telephone service provider.
To activate Call Forwarding:
Step 1 Take the phone off-hook.
Step 2 Dial *feature number* phone number to be forwarded to #.
Step 3 Hang up. You may hear a confirmation signal from the network before you hang up.
To deactivate Call Forwarding:
Step 1 Take the phone off-hook.
Step 2 Dial #feature number#.
If the wrong feature number is entered, you may hear a signal indicating the wrong feature number was entered or the activation or deactivation failed.
Activation: *21*forwarded-to number#
Deactivation: #21#
Activation: *61*forwarded-to number#
Deactivation: #61#
Activation: *67*forwarded-to number#
Deactivation: #67#
The switch type NET3 supports these features where the country group must be set for Sweden and Finland.
There is no equivalent command-line command to activate or deactivate Call Forwarding. The phone number to which calls are redirected is not displayed.
All types of Call Forwarding supplementary services must be provisioned on the ISDN line for the service to be available.
