Hi, I currently have a cisco 1841 router and i'm trying to upgrade it to ips v5 sigs
however it seem that it won't let me, all it will accept is the .sdf files,
i'm running ios c1841-adventerprisek9-mz.124-18.bin
however it doesn't seem to support the v5, can anyone let me a hand or point me in the right direction where i'm going wrong? Thanks in advance.
I don't have enough memory, an upgrade kit has already been ordered, but I don't know when it will get here. I'll try an remember to test and post.
Try IOS version 12.4(15)T3
