Cisco 881 IOS Update Problem

[giedrius.noreikis]

Hi,

after an update of CISCO881W-GN-E-K9 IOS image from:

c880data-universalk9-mz.124-20.T3 (which came with the router)

to:

c880data-universalk9-mz.124-24.T5

all the IGMP/PIM-related commands seem to be gone. Immediately after the reload I got some errors:

ip pim sparse-dense-mode
     ^
% Invalid input detected at '^' marker.

<skip>

ip igmp access-group 60
     ^
% Invalid input detected at '^' marker.

control-plane
    ^
% Invalid input detected at '^' marker.

At the command prompt "show ip igmp ..." produces the same "Invalid input detected ..." error.

After downgrading to the good old c880data-universalk9-mz.124-20.T3 the commands start working again.

I am unable to find an explanation for this. Feature Navigator shows all the related features available in the new image as well. Maybe someone will be able to point out what could be wrong.

Thanks in advance!

Hi,

It maybe a bug in that version.

Does this happen if you load a later version (IOS 15)?

Dear Reza,

I've tried some more versions, so to conclude:

c880data-universalk9-mz.124-20.T3 - works ok (native image)

c880data-universalk9-mz.124-24.T - works ok

c880data-universalk9-mz.124-24.T5 - commands not recognized

c880data-universalk9-mz.150-1.M - commands not recognized

c880data-universalk9-mz.151-3.T1 - commands not recognized

c880data-universalk9-mz.151-4.M - commands not recognized

Now I start thinking it's a licensing issue - it could hardly be a bug in so many versions.

Thanks for a hint,

Giedrius

Hi,

It might not have booted with the correct license. I checked on a 887 router and when reloading with 12.4(24)T2, it loaded the advanced security license which did not have the multicast related commands. After enabling advanced ip services (license boot module c880 level advipservices), the commands got recognized.

You can check the license level via the commands: show version or show license.

If the commands are still not recognized with the correct license, indeed might be a bug and it would be worth checking out 15.0 (if the DRAM and flash allows it)

Warm Regards,

Dear Rose,

I performed all the updates by copying a new image and deleting the old one (i.e. no "license boot" or "boot system" commands). The 12.4(24)T works ok, but the others not. I wonder how, depending on what, the licenses are being loaded.

When running the original 12.4(20)T3 image, "show license" output is:

Index 1 Feature: advipservices

        Period left: 8  weeks 4  days

        License Type: Evaluation

        License State: Active, Not in Use, EULA not accepted

        License Priority: None

Index 2 Feature: advsecurity

        Period left: Life time

        License Type: Permanent

        License State: Active, In Use

        License Priority: Medium

And "show version" gives the following license-related info:

License Information for 'c880-data'

    License Level: advsecurity   Type: Permanent

    Next reboot license Level: advsecurity

Since all the multicast related commands are working, does this mean I am still using the "advipservices" license which is marked as "Not in Use" in the output? I obviously do not understand the licensing

I will try to play with the router more on next weekend.

Thank you for helping,

Giedrius

Hello Giedrius,

I am sorry, I did not get a notification when you sent the reply

I have not checked the older image but the "not in Use" indeed means that it is not actually activated. It seems quite strange because all of my research says that we would need advipservices for multicast.

When reloading with the newer release, it would boot the advanced security by default and it does not seem to be enough anymore.

You can boot the advipservices license:

license boot mod c880 level advipservices

It would need a reload after that for the license to take effect (you might have already found this though).

Warm Regards,

Rose
