Kamil,
Looks pretty good but it probably won't run as is. You'll need to change:
my $sysUptime = '1.3.6.1.2.1.1.3;
to
my $sysUptime = '1.3.6.1.2.1.1.3.0';
and it should run fine.

The exact code would depend on whether your ASA is configured for SNMPv2 or SNMPv3. Which SNMP version is configured on this device?
For a PERL script you would need some PERL modules or have the SNMP utilities installed, which you could then call from within the PERL script or simply call the SNMP client from a SHELL script. The exact syntax of the SNMP query depends on the installed SNMP package on the systems issuing the query. You could always read the man page (man snmpget) or run a query with the -h switch (snmpget -h) to find out how to build your query. I would need more info as to how the SNMPv3 agent on the ASA is configured to build a proper example of the SNMPv3 query.
This simple SNMPv2 example is for NetSNMP package version 5.6.2.1 with 'public' being the default read-only community string for SNMP queries:
snmpget -v2c -c public yourhostname .1.3.6.1.2.1.1.3 or snmpget -v2c -c public yourhostname .1.3.6.1.2.1.1.3.0
and should return the ASA's uptime since the last restart.
Inside the PERL script you would write the query to a string and then print the string to the screen:
$uptime = `snmpget -v2c -c public yourhostname .1.3.6.1.2.1.1.3.0`;
print $uptime;
Hope this gets you started.

Hello, We have a series of 3750G access switches running 12.2(52)SE with IP SLA responder enabled. They are polled by a router outside a firewall. All switches reside on a Management VLAN using RFC1918 IPs with their default gateway address in the same Management VLAN. In order to allow router access to the IP SLA responder we provided the ability to route the packet back to the monitor by configuring an SVI. The SVI IP corresponds to the configured Host VLAN on these switches. This worked and still works great on the 3750G switches. When we upgraded some switches to 3750X platforms with IOS 15.0(2) the IP SLA monitor for the responders on the 3750X switches started timing out. As before, we see the router sending the IP SLA control packet to the SVI's IP address -- the response contains the switch's RFC1918 address rather than the SVI IP-address and therefore can't get back to the router. IP SLA functionality works fine on the 3750Xs as long as the queries stay on the Management VLAN. So, it's apparent that the issue seems to be with routing when sending the control packet to the SVI IP. Any ideas if there were changes in 15.0(2) that would induce this behavior? Do we have other options than to create a single-host static route for the router on the 3750Xs? Any help would be much appreciated. Thanks!! = Uwe =

We wanted to see if there were any other solutions because we didn't want to lose the historical data but eventually deleted it and then let auto-discovery re-add it. That seems to have taken care of the problem. Thanks, Joseph!

We just replaced some older routers with 1941's running the K9 of 15.0(1)M3 and "Sync on Device" no longer works in RME 4.2.0 and throws the following error: CM0100 Copy PRIMARY Running Config to PRIMARY Startup Config on device failed Cause: MgmtOperation RUNNING2STARTUP is not supported on automatically supported. However doing this manually on the router works just fine. #copy running-config startup-config Destination filename [startup-config]? Building configuration... [OK] The cause for the "out of sync" is shown below: Startup config: Using 5116 out of 262136 bytes Running config: Building configuration... Current configuration : 5116 bytes The "out of sync" errors persist even after manually doing a 'copy running-config startup-config`. Any help would be appreciated. Also, is there a list of exclude commands? Thanks...!!! = Uwe =

I had the same problem and believe the issue is that you probably have a trap server configured and are using the same snmp-server group for the trap server and your queries. I created another group for SNMPv3 queries and the configuration no longer seems to get overwritten. Here's what I did. Go into config mode and create a group just for the trap server - let's call it TRAPS. I used priv and it looks like that's what you use. Don't worry about defining any MIB views as this group will automatically populate the notifyview once the trap servers below are added to the config. (...and will remove the readview and writeview entries after reboot - that's why a second group is needed). Remove your old trap server entries and set up the new trap server using the new group called TRAPS. snmp-server group TRAPS v3 priv snmp-server host version 3 priv TRAPS Now create another group for queries only - (let's call it QUERIES but you could just use your current group XXX since it's already set up) - I like the v1default MIB view for both reads and writes but you can limit the MIBs with the snmp-server view command. I am using md5 and des56 here - your case may be different - and set up the user (or keep the one you already have configured) snmp-server group QUERIES v3 priv read v1default write v1default access snmp-server user QUERIES v3 auth md5 priv des56 Exit and check the config. The group TRAPS should have the notifyview set. The group QUERIES should have the readview and writeview set to v1default (or whatever view you chose to enter here). The two SNMPv3 groups should look like this: #sh snmp group groupname: TRAPS security model:v3 priv readview : writeview: notifyview: *tv.FFFFFFFF.FFFFFFFF.FFFFFFFF.F row status: active groupname: QUERIES security model:v3 priv readview : v1default writeview: v1default notifyview: row status: active access-list: 4 The old trap server entry using the old group XXX should have been removed already. Verify that the user: entry says TRAPS #sh snmp host Notification host: xxx.xxx.xxx.xxx udp-port: 162 type: trap user: TRAPS security model: v3 priv Finally make sure the user is in the correct group (QUERIES): #sh snmp user User name: Engine ID: xxxxxxxxxxxxxxxxxxxxxxxxxx storage-type: nonvolatile active Authentication Protocol: MD5 Privacy Protocol: DES Group-name: QUERIES If all is well - write the config. You should now be able to perform a coldstart without losing your SNMPv3 config. Please, let me know if this worked for you.

One addition to this. Just noticed that the server having trouble displaying the Events Summary also won't run DFMCTMStartup. When starting it either from CLI with pdexec or from the GUI the process will only run for 1 second before it gets shut down with state: "Administrator has shut down this server".

Hi, we have two stand-alone LMS 3.1 boxes running Solaris 10 which are identically configured. Both recently began to have issues with the DFM. When refreshing the DFM window manually we see the following for the High Severity Alerts: High Severity Alerts An exception occurred. Please check the AAD.log file for further details. This is always followed ~45 seconds later by a normal refresh of the HSA portlet showing the High Severity alerts. When this occurs we also notice this problem: DFM Events Summary Cannot retrieve Device Summary, Please see the DeviceManagement.log file for more information. This behavior is observed on both servers. The issue below, however, is only seen on one of them. The DFM Events Summary portlet shows this when the above error isn't present: DFM Events Summary No Devices are encountered with Critical Events. There are Critical Events in the history for this server and they are shown in the High Severity Alerts portlet. When setting up the DFM Events Summary portlet to use identified critcal events (ie. HighUtilization, OperationallyDown, Flappeing etc) the portlet will always show a count of '0' for any and all selected events. We also noticed that the numbers in the CS Device Allocation Summary and the known hosts in DFM were off by one (555 vs 552, respectively). The identified host was removed from CS and manually re-added. However, the known hosts in DFM after rediscovery still only show 552. Don't know if these two issues are related but I thought I'd mention it since it needs to be fixed, as well Any help would be appreciated. Thanks!!! = Uwe =
