Faq (CISCO881-K9)

Does CISCO881-K9 support Ethernet broadband?


I inherited an 881W and want to update to the latest IOS. The AP has the buggy 12.4 IOS. Should I upgrade the router or the AP first?

It doesn't matter, they are each independent of each other.

Is the router memory upgradable?

An appropriate amount of router flash memory has been integrated for the different Cisco 880 Series hardware models, and it is not upgradable. DRAM is upgradable on the Cisco 880 Series only. Refer to the Cisco 880 Series data sheets for default memory configurations and upgrade options.

Does Cisco Security Manager support the CISCO881-K9?

Cisco Security Manager Version 3.2.1 supports the Cisco 881 and 888 platforms.

What is the Cisco IOS Software Activation feature?

Software activation authorizes and enables use of a Cisco software feature or feature sets. A special file contained in the device, called a license file, is examined by Cisco software when the device is powered on. Based on the license file installed, Cisco software enables the appropriate feature sets.

Is hardware-based encryption available on the CISCO881-K9?

Yes. Hardware-assisted IP Security (IPsec) Triple Data Encryption Standard (3DES) and Advanced Encryption Standard (AES) encryption is available on the Cisco 880 Series; 128-, 192-, and 256-bit keys are supported for AES.

Which Cisco IOS Software releases does the CISCO881-K9 support?

The Cisco 880 Series routers support Cisco IOS Software Release 12.4(20)T and later.

What kind of 3G modem is integrated with the Cisco 880 Series routers?

When ordered with the 3G part number, the Cisco 880 Series is bundled with a modem branded by Cisco and supplied by Sierra Wireless: AC597E 3G modem for the Code Division Multiple Access (CDMA) network or AC880E 3G modem for the Global System for Mobile Communications (GSM) network.

Can I boot a Cisco IOS Software image and Cisco IOS Software configuration file from the USB flash memory installed on the CISCO881-K9?

During the router reload process, the Cisco 880 Series automatically searches for a bootable Cisco IOS Software image on the USB flash memory if no bootable image is available on the onboard flash memory. A Cisco IOS Software configuration file can be booted from the USB flash memory only if the Cisco IOS Software command boot config usbflash0: is part of the router startup configuration stored in NVRAM.

Are there any hardware upgrade options for CISCO881-K9?

No. The Cisco 880 Series routers are fixed-configuration integrated services routers that do not have hardware upgrade options (except for memory). You must decide the hardware configuration of the router by selecting the desirable product number when you order.
