Re: Serial interface dont appears in my config

You do not have the correct IOS to support the WIC-1T. What image do you currently have, I can give you the name of the one you need if you give me the version you have and what your needs are.

Here is a link to check which IOS you need for the WIC-1T and the 1721. You just go to option two and select the drop down for WIC-1T.

I've also noticed when you have configured virtual templates (used mainly for async routing) associated with serial int's, you do not see the serial configuration when a 'sh run' cmd is executed ...

As I said before, your IOS. You must download a different version.

Re: Serial interface dont appears in my config

For the 1721, the wic-1t is not supported in mainline 12.2 code but is in 12.2T. As per the HW/SW matrix, these are the minimum supported IOS levels for the wic-1t and 1721.

12.2(4)YA, 12.2(4)YB, 12.2(4)YH, 12.2(8)T, 12.2(8)YJ, 12.2(8)YL, 12.2(8)YM, 12.2(8)YN, 12.2(11)T, 12.2(11)YU, 12.2(11)YV, 12.2(13)T, 12.3(1)

Re: Serial interface dont appears in my config

Hello all,

Thanks for your help, now i use c1700-y-mz.122-4.YA2 IOS, i can see the serials (WIC-1T) but dont supprot IPSEC.

Now, i would use IPSEC 3DES in my router so it has only 32 mB Ram and 16 MB Flash.

Wich Release can i use in this case.

Re: Serial interface dont appears in my config

Unfortunatley you need a minimum of 48Mb of DRAM for all 1721 IPSec images that support the WIC-1T:

12.2T

File name Min. Memory(MB) Min. Flash(MB)

c1700-k9sy7-mz.122-15.T11.bin 48 16

12.2YA

File name Min. Memory(MB) Min. Flash(MB)

c1700-k9sy7-mz.122-4.YA6.bin 48 16

12.3

File name Min. Memory(MB) Min. Flash(MB)

c1700-advsecurityk9-mz.123-5b.bin 48 16
