Memory Requirements

This section describes the memory requirements for the Cisco IOS feature sets supported by Cisco IOS Release 12.1(1)XB on the Cisco 827 and Cisco 827-4V Routers.

Table 1 Memory Requirements for the Cisco 827 and Cisco 827-4V Routers

Platforms	Image Name	Image	Recommended Flash Memory1	Recommended DRAM Memory	Runs From
Cisco 827	IP	c827-y6-mz	12 MB	16 MB	RAM

Cisco 827-4V	IP/IPX Voice Plus	c827v-nsy6-mz	12 MB	24 MB	RAM

1 Cisco 827 routers use 4 MB of Flash memory for storing internal information such as the ROM monitor. Only the remainder of the Flash memory is available for storing Cisco IOS images and is displayed by using the command show flash.

Hardware Supported

Cisco IOS Release 12.1(1)XB supports the following Cisco 800 series routers:

•Cisco 827

•Cisco 827-4V

For detailed descriptions of new hardware features, see New and Changed Information.

Cisco 827-4V	One 10BaseT (RJ-45)	RJ-45	Four (RJ-11)	RJ-45

Cisco 827 and Cisco 827-4V Routers

The Cisco 827 and Cisco 827-4V Routers provide the following key hardware features:

•The routers provide connection to an ADSL network or telephones and fax machines through an ADSL port.

•Flash memory: Default is 12 MB and is expandable to 20 MB. If 12 MB is Flash is installed, 4 MB hosts the ROMMON and NVRAM and 8 MB is used for the Cisco IOS images.

•Cisco 827 Router Dynamic RAM: Default is 16 MB of DRAM and is expandable to 32 MB.

•Cisco 827-4V Router Dynamic RAM: Default is 24 MB and is expandable to 32 MB. The Cisco 827-4V Router also contains an 8-MB DIMM card.

•The central processing unit is a 50 MHz MPC 855T RISC processor.

•Color-coded ports and cable reduce the chance of cabling errors.

•Routers can be stacked or mounted on a wall.

•The routers provide locking power connectors and a Kensington-compatible locking slot.

Determining Your Software Release

To determine the version of Cisco IOS software currently running on your Cisco 800 series router, log in to the router and enter the show version EXEC command. The following sample output from the show version command indicates the version number on the second output line:

router> show version

Cisco Internetwork Operating System Software 

IOS (tm) 800 Software (c827-y6-mz), Version 12.1(1)XB, RELEASE SOFTWARE

Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.

New Hardware and Software Features in Release 12.1(1)XB

The following sections list the new hardware and software features supported by the Cisco Cisco 827 and Cisco 827-4V Routers for Release 12.1(1)XB.

Cisco 827 and Cisco 827-4V Routers

The Cisco 827 and Cisco 827-4V asymmetric digital subscriber line (ADSL) routers use Cisco IOS software to provide business-class functionality for small- and medium-sized business offices and corporate telecommuting workers. The routers support up to 20 users in a small office or telecommuting environment with differentiated classes of service, integrated toll-quality voice and data, business-class security, and manageability.

Important Notes

The following sections contain important notes about Cisco IOS Release 12.1 that can apply to the Cisco 827 and Cisco 827-4V Routers. (Also, see the "Caveats" section.)

ADSL Cable Requirements

The ADSL cable that you connect to the Cisco 827 router must be 10BaseT Category 5, unshielded twisted-pair (UTP) cable. Using regular telephone cable can introduce line errors.

DHCP Client Support

Perform the following steps to configure the router for DHCP client support:

---

Step 1 Configure the BVI interface by entering the command ip address dhcp client-id Ethernet 0.

Specifying the value client-id ethernet0 causes that the MAC address of the Ethernet interface to be used as the client ID when the DHCP request is sent. Otherwise, the MAC address of the BVI interface is used as the client ID.

Step 2 Configure NAT.

a. Configure the BVI interface by entering the nat outside command.

b. Configure the Ethernet interface by entering the nat inside command.

c. Create an access list under NAT by entering the access-list 1 permit ip address command to match all Ethernet IP addresses.

d. Configure the source list under NAT by entering the command ip nat inside source list 1 interface BVI 1 overload.

Step 3 This step is optional. Configure the Cisco 827 router to act as a DHCP server.

a. At the config-if router prompt, enter the server name command ip dhcp pool.

b. Enter the command import all to have the Cisco 827 router retrieve the Microsoft Windows nameserver (WINS) and domain name system (DNS) server addresses for name resolution.

Downloading Images

Delete files in the router Flash memory before attempting to download new images.

---

Caution Use the delete command, not erase, to free up space. Entering erase removes all files, including the configuration.

---

Flash Memory

Cisco 827 routers use 4 MB of Flash memory for storing internal information such as the ROM monitor. Only the remainder of the Flash memory is available for storing Cisco IOS images and is displayed by using the command show flash. For example, if the router reports 8 MB of Flash, the actual amount of onboard Flash memory is 12 MB, even though only 8 MB are displayed and available for Cisco IOS image storage.

Multilink PPP and Interleaving

Multilink PPP fragments large data packets to allow small voice packets to be interleaved between them. However, apart from first-in-first-out (FIFO) queuing, no other kind of output queuing mechanisms are currently supported with PPP over ATM. Consequently, when multilink PPP is configured on the Cisco 827 routers, large packets are fragmented, but small voice packets are not interleaved between them.

NAT Support for H.323 Signaling

NAT does not support alerting H.225 messages, therefore, NAT communication cannot be established between router end points. NAT support for H.323 signaling is limited to the application Netmeeting.

Phone Mate Answering Machine Model 9200

Phone Mate model 9200 answering machines fail to recognize the ringing signal sent by AMD R79 ringing SLIC. Tests were performed with the Phone Mate models 3750 and 9300.

PPP over AAL5SNAP Encapsulation Support

PPP over AAL5SNAP encapsulation is currently not supported, although the context sensitive help mentions that it can be configured.

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.

All caveats in Release 12.1 T are also in Release 12.1(1)XB. For information on caveats in Cisco IOS Release 12.1 T, refer to the Caveats for Cisco IOS Release 12.1 T document. For information on caveats in Cisco IOS Release 12.1, refer to the Caveats for Cisco IOS  Release 12.1 document. These publications list severity 1 and 2 caveats, and are located on CCO and the Documentation CD-ROM.
