Cisco :: WLC-5508 Logging To The Syslog?

Dec 4, 2011

It appears that there are two different types of log information generated by the WLC-5508.  The stuff that can be sent directly to syslog seems to be very basic while most of the good log information is sent via snmp trap.  Does this setup to log to a SIEM in a manner that gives a good security view into the wireless controller?

Cisco AAA/Identity/Nac :: ACS Logging To Syslog Server - Time Off 5 Hours

Dec 12, 2011

I am sending TACACS administration logging to a syslog server.  When the messages show up on the syslog server, they are 5 hours ahead of the actual time.  Time on the ACS is correct - local logging shows the correct time.  Time on the syslog server is correct...all other devices/systems sending syslog messages to it are coming through with the correct time.  why the ACS syslog messages would be 5 hours ahead?

Cisco Firewall :: ASA 5585- TCP Syslog / Logging Permit-Host Down

Jul 5, 2012

We have a firewall service environment where logging is handled with UDP at the moment. Recently we have noticed that some messages get lost on the way to the server (Since the server doesn't seem to be under huge stress from syslog traffic). We decided to try sending the syslog via TCP. You can imagine my surprise when I enabled the "logging host <interface name> <server ip> tcp/1470" on an ASA Security context and find out that all the connections through that firewall are now being blocked. Granted, I could have checked the command reference for this specific command but I never even thought of the possibility of a logging command being able to stop all traffic on a firewall.
The TCP syslog connection failing was caused by a mismatched TCP port on the server which got corrected quickly. Even though I could now view log messages from the firewall in question in real time, the only message logged was the blocking of new connections with the following syslog message: "%ASA-3-201008: Disallowing new connections."
Here start my questions:
- New connections are supposed to be blocked when the the TCP Syslog server are not reachable. How is it possible that I am seeing the TCP syslog sent to the server and the ASA Security Context is still blocking the traffic? 
- I configured the "logging permit-host down" after I found the command and it supposedly should prevent the above problem/situation from happening. Yet after issuing this command on the Security Context in question, connections were still being blocked with the same syslog message. Why is this? 
- Eventually I changed the logging back to UDP. This yet again caused no change to the situation. All the customer connections were still being blocked. Why is this? 
- After all the above I removed all possible logging configurations from the Security Context. This had absolutely no effect on the situation either. 
- As a last measure I changed to the system context of the ASA and totally removed the syslog interface from the Security Context. This also had absolutely no effect on the situation. 
At the end I was forced to save the configuration on the ASAs Flash -memory, remove the Security Context, create the SC again, attach the interfaces again and load the configuration from the flash into the Security Context. This in the end corrected the problem. Seems to me this is some sort of bug since the syslog server was receiving the syslog messages from the SC but the ASA was still blocking all new connections. Even the command "logging permit-host down" command didn't wor or changing back to UDP.
It seems the Security Context in question just simply got stuck and continued blocking all connections even though in the end it didn't have ANY logging configurations on. Seems to me that this is quite a risky configuration if you are possibly facing cutting all traffic for hundreds of customers when the syslog connection is lost or the above situation happens and isn't corrected by any of the above measures we took (like the command "logging permit-host down" which is supposed to avoid this situation altogether).

Cisco Security :: Can Add SSM-4GE Module In ASA5540-AIP40-K8 Firewall

Dec 11, 2011

I have requirement received from one of my customer. the part number given as ASA5540-AIP40-K8, same time requesting for addition of another 4Port GE Module (i believe its SSM-4GE Module). Is any option to add this module in to the above specified model (ASA5540-AIP40-K8).
As per my understanding the ASA5540 have the option to add 1 additional module only, so if we AIP-SSM module, we don't have any free slot left with to add another SSM-4GE Module in the firewall.
i am not getting even the option to add SSM-4GE in the ASA5540-AIP40-K8

Cisco Routers :: SA 500 - Ability To Send Syslog Events To Multiple Syslog Servers

Jul 7, 2012

Add the ability to send syslog events to multiple syslog servers in the SA500 Series routers.  I know the functionality is currently in the RV220W because we utilized it.  It would be great if you could configure the syslog servers by event type as well.  For example, being able to send the kernel events to syslog server A, and all other events to syslog server B.

Cisco Firewall :: ASA 5520 - ASDM Logging - Disable Rules Logging

Nov 16, 2011

I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?

Cisco VPN :: Multiple Certificates On ASA5540?

Sep 4, 2012

I have an ASA5540 running 8.4(3) which has CA and identity certificates from installed, identifying the ASA to VPN remote users (the are using the anyconnect client.) There is also a separate certificate server located on the inside LAN that is used for internal purposes.  All client workstations have identity certs from this internal server.
We would like to be able to continue using the existing godaddy CA/identity certs to identify the ASA to the clients, but we'd like to use the internal CA server to identify the clients when they initiate the AnyConnect session to the ASA.
I have seen other postings that state you cannot have more than one vert on an interface, but this is a little different - only one cert needs to be used to identify the ASA.  The other one is only to identify the users.  The ASA did allow me to import the internal CA cert.

Cisco Firewall :: K-value Mismatch With EIGRP On ASA5540

Mar 7, 2011

I have an ASA- 5585X (v.8.2.4) directly connected to an upstream 6509, which is running EIGRP. I configured the ASA for EIGRP with same AS# and network numbers and no auto-summary.   Here are the log messages I got:
Mar  8 15:11:08: %PIM-5-NBRCHG: neighbor UP on interface Vlan150 (vrf default) Mar  8 15:11:08: %PIM-5-DRCHG: DR change from neighbor to on interface Vlan150 (vrf default)
Mar  8 15:11:11: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor (Vlan150) isup: new adjacencyMar  8 16:16:08: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor (Vlan150) isup: new adjacency
Mar  8 16:18:54: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor (Vlan150) is down: K-value mismatch
I lost my SSH connection to the upstream 6509 and couldn't get it back. Luckily I didn't lose my ASDM connection to the ASA, so I disabled EIGRP and went to look at the logs on the 6509.
What causes a K-value mismatch, and how to I rectify the situation?

There is no problem with users who are using 3.5.1 and 5.0(64 bit), but 4.8 and 5.0 (32 bit) vpn clients can not add ARP entry to Windows machines ARP table. If i add ARP entry for x.x.x.255 on VPN interface, they can work.
