SMB appliances regular updates and policy pulls

Jump to solution

The big difference when comparing centrally managed SMB to a standard CP Gateway is that we have no policy install, but rather a policy pull from the device - very appropriate for DAIP configurations ! The SMB GW asks the Management every 5 minutes if the policy has changed - see the corresponding entries in /var/log/log/sfwd.elg:

[sfwd 4538 2000560128]@zwelfhundertr[19 Mar 10:06:59] Fetching Security Policy from '172.27.39.198'
[sfwd 4538 2000560128]@zwelfhundertr[19 Mar 10:06:59] Local Security Policy is Up-To-Date.
[sfwd 4538 2000560128]@zwelfhundertr[19 Mar 10:06:59] The Security Policy was not installed because it is the same as the Policy already on the Module.

Firmware upgrade check can also be found in sfwd.elg - it is logged additionally also in

/var/log/log/check_available_firmware.elg:

[check_available_firmware 5451 1996578816]@zwelfhundertr[14 Mar 13:35:53] check_available_firmware: Thu Mar 14 13:35:53 2019

Licenses are synced with UserCenter every hour - see /var/log/log/uc_activation.elg:

TED wants all 12 hours his License refreshment, see /var/log/log/ted.elg:

[ 12673 2002706432][16 Mar 2:13:54] [TE_TRACE]: Starting licenses refreshment

So we can see that there is really a lot of work to do even for the small ones 😉

What i also know is the clish variant: # fetch policy mgmt-ipv4-address x.x.x.x#

But i fear that also here only the compiled policy from SMS is checked and local policy not discarded ! But of course we have a method to achive what you want:

- switch Security Management to local mode
- switch back to central mamagement
- re-establish SIC with the SMS
- Security policy is loded from SMS and installed

Gunther,
Do you know if the fw fetch on SMB can be forced? We recently had a 1100 gateway that just did not want to update it's policy and finally after a reboot and push on a fixed IP, I was able to replace the policy, it just did not update before that.

Yes, see sk117473: Manual policy fetch on SMB device

# fw -d fetch

Nope, that is a debug, but still uses the local policy, does not force a fetch from management.

Yes, it is debug for much more fun 😉

[Expert@zwelfhundertr]# fw fetch
Fetching Security Policy from '172.27.39.198'

Local Security Policy is Up-To-Date.

Installing Security Policy...

Installing Security Policy Succeeded.
Done.
[Expert@zwelfhundertr]#

Also possible to use as fw fetch <ip address of mgmt>. According to sk119332, Security policy changes must be pushed to the Security Gateway before they will be implemented by an "fw fetch" command. The "fw fetch" compares the compiled policy on the Security Management server with the latest policy on the Security Gateway.

Gunther,

I am aware of how it should work, but in some cases you did make changes and the gateway (in our case) just kept saying the local was up to date and the GUI showed a policy installed at 10:30 while we made changes at 10:45 and pushed policy, log was flowing, but at 11:00 it was still showing that the 10:30 policy was loaded.
Doing the fw fetch also said local security policy is up to date.
Hence I wanted to see if there is a way to Force the fetch and discard the local copy.

Here you should involve TAC - policy install is done to make the GW use the new rules, so such a behaviour is a bug !
