Re: Very Urgent!!

DRAM FLASH

4 8 IP

6 12 IP/IPX/FW/PLUS

Depends on your image if you can load this or not on what feature set is in your code you are trying to load up. As you see above from IP to the FW feature set it ranges a good bit.

Compressing the image on your TFTP server will not work. You must meet memory requirements. Some images will load without the minimum but if you have problems you'll likely need to address this first.

Hope this helps you,

Re: Very Urgent!!

Looks like you should be able to do this, except on your 12.0.8 running routers. Those will need to be upgraded. These features are in the following code 12.2(16) 12.0(2a)T1

1-LLQ with priority

2-frame relay traffic-shaping

3-IP rtp header-compression

4-Output service policy in the map-class associated with Dlci

5-FRF.12 to fragment the packets ( 80 Bytes )

Hope this helps you,

Re: Very Urgent!!

Dear Don,

I don't have access to the IOS software download site, but i have managed to have the IOS 12.1 (13) " c1600-sy-l.121-13" but its size is 7,891KB and that's more than the 4 MB flash i have on the router 1601..

First ,is this version ok to manage the Qos ?

Second, what can i do to install this software version of the 4MB flash and 8MB Dram 1601 router?
