May 28, 2011

We have a VPN concentartor which is having few VPN and doing  NAT (Static and PAT) as well. One of our customer has added huge number  of serves so we have to do hundreds of static and PAT rules.we have  really large number of customers which are growing and do so the NAT in  VPN concentartor.
 
I am bit concern and want to know what will be the best way to check that how my VPN concentartor is doing .As we all know its a GUI i try to check few stuff but couldnt get any info.... the model number is 3015.

Cisco Firewall :: ASA 5520 CPU Utilization Is 100 %

Sep 27, 2011

We have configured 20 route in ASA 5520. The CPU usage goes to 100 % at the moment when we add a specific route.route inside 10.254.101.0 255. 255. 255.0 10.254.102.254 1.This is the same case when we add this route at the first cli or as the 10th cli or the 21 cli (errespective of the position of cli) There is an another route out of which 20 routes we have configured is route inside 10.254.103.0 255.255.255.0 10.254.102.254 1.The normal case if we dont add the problamatic route , then the CPU utilization is only 2 %.

Cisco Firewall :: PIX 501 - Memory Utilization?

Jul 6, 2011

I've deployed many Cisco PIX 501 v6.3.3 either as normal firewalling feature and/or with VPN features enabled. I noticed in all my deployments, regardless if it's during peak hours or after office hours, the memory utilization is always consistent 11MB utilized over the total of 16MB(memory default size).

Cisco Firewall :: High CPU Utilization On ASA 5550?

Mar 10, 2013

I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
 
1. The ASA hardware was haivng problem

2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
 
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
  
Downgrading any license (for example, going from 10 contexts to 2 contexts).
 
# Note If  a temporary license expires, and the permanent license is a downgrade,  then you do not need to immediately reload the security appliance; the  next time you reload, the permanent license is restored.
  
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
 
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
 
I am not sure what could be the issue that the servers in the DMZ wen unreachable.

Cisco Firewall :: High CPU Utilization On ASA 5540

May 11, 2008

I have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. How I can find the root cause of the CPU high utilization?

Cisco Firewall :: PIX525 Sudden High CPU Utilization?

Feb 22, 2013

Would like to ask for everyones assistance with regards to the problems we are encountering on our PIX525 firewall. Our encountered problem is as follow."PIX 525 experience sudden high CPU utilization every time a Vulnerability System Scan (third part app) is conducted. Based on the previous experiences, the high CPU utilization where experience when a host on a particular VLAN (214) is being scanned. Whenever we removed the said VLAN (214) in the network the CPU utilization of PIX 525 comes back to normal and all connectivity were resumed."The problem just recently appeared, we are conducting vulnerability system scan before and it goes successfully.

Cisco Firewall :: Very High Memory Utilization In PIX 515e?

Feb 15, 2012

We had two PIXes in our environment and working as a active-failover mode. Its noted in now a days the active PIX memory utilization is 98% and for standby PIX it is 96%. And also in some times we were experiencing packet loss to the ip of active PIX and which reflects in the inside servers access also. During that time the active pix was not accessible via ssh as well as ASDM. We have tried reloading the PIX and changing failover state of the PIX, but it results only a temporary solution. Current memory installed is 128 MB (maximum upgraded), so a upgrade is also not possible. Please see the show command outputs from the PIX. Current Software version is 7.2(4)
 
sh memory output (PIX 1 - active)
 Free memory:         4850944 bytes ( 4%)
Used memory:       129366784 bytes (96%)

[code]....
 
1) How we can pin point the root cause of this high memory utilization?

2) What might be the reason for the high memory utilization for the standby pix (96%), still the PIX is in idle state?

3) Is it a hardware issue or a memory leak issue, then how can we find out?

4) Is a software upgrade to new version resolves the memory issue?

We recently added about 400 users to our network for a total of 1000.  Looking at the ASDM we are holding very tight to 75% utilization and we have 256mbs.  This is also running IOS 8.2(1).  Our firewall recently crashed after a major download was forced through it.  This was after only being booted up for about a week.  We had reloaded it a week prior after having ran it for about a year without issue.  We havent made any changes in the last month other than adding more users to our network.

Cisco Firewall :: PIX515E - Internal Nodes / Bandwidth Utilization?

Jan 13, 2013

The infrastructure has PIX515E as the Firewall and few Web Servers and Database Servers inside. Is it possible to retreieve information regarding the bandwidth available at the outside interface of PIX (Internet link utilization ) utilized by each of the nodes seperately? I could use SNMP to get the overall data transfer at the Outside interface of PIX but isit possible to get utilization details of individual nodes ? Is Netflow an option ?

Cisco Firewall :: ASA5580-20 High Cpu Utilization In System Context

Nov 7, 2011

We have an active-active pair of cisco ASA5580-20 with software version 8.4(1)9. There are 8 contexts on it (including admin and system). 1 context is active on Primary node and other 7 are active on Secondary node. User traffic is going through this 1 context (2 interfaces - inside to users, outside to internet) and there are peaks to 1.16M concurrent connections, max bandwidth is 1.25Gbps. CPU usage for this context in peak hours is 63%, but we noticed that when we run "show cpu usage context all" from system it shows that system context is using 25% of CPU and "Total CPU utilization" (form output of show cpu detailed - on system context) is 88% which is bad. In non peak hours - user context use 33.6% CPU, system use 14.5%, total CPU usage is 50.5% So, is it normal this cpu utilization on system context (system on Primary node)?

How Much CPU Utilization Is Too Much

Sep 7, 2011

I haven't covered this bit in my CCDA studies (yet) but I was thinking, what do people consider too much CPU utilization for:-

A) A switch during normal working hours? (Layer 2 Switch)

B) A Router during normal working hours?

I was thinking a normal level for a switch would be at max 10% and I would get worried at 50-60% if this lasted for several minutes at a time.For a Router I would expect higher utilization in general so I would think up to about 25% during normal usage and at worst case a prolonged period the same as the switch.This isn't something I see discussed very often, except maybe by me when a router goes mental and maxes out at 100%.

Cisco :: LMS 4.2 - CPU Utilization Reports

Jun 7, 2012

We have CPU reports set to run daily for some of our higher priority switches, and we've noticed that some of the data isn't meshing with what we see on the switch. We have one heavily utilized switch that reports near 100% CPU utilization sometimes. I can do a "show proc cpu history" on that switch and see that at least once an hour over 72 hours, we'll see a near 100% CPU utilization.
 
The problem is that these spikes never appeare on any of our reports. We'd like to see this info because even if the switch spikes for just a few seconds or a minute, it could still indicate that we may have issues. Without that in the report, we may never realize there could be a problem.
 
Is there a way for this info to show in the report? I'm under the impression that if LMS polls the switch and doesn't see a high utilization average, then maybe it doesnt' enter that in the report. I guess I'd just like to know how often it pulls this data, and how it decides wath the Min, Max, and Averages are.

AAA/Identity/Nac :: ACS 5.4 CPU Utilization

Mar 28, 2013

We are currently running ACS 5.4.0.46.0a in a VMWare environement. We have 1 Primary and 1 Secondary running on our ESXi 5.0 cluster at our HQ and 1 secondary running on a standalone ESXi 5.0 at our DR site. All three instances were created at the same time and configure identical. The only difference being the physical box they are running from and that the secondary running on the ESXi cluster is the log collector. We are in the process of migrating from ACS 4.2 and only have 3 systems that authenticate to the new ACS 5.4 servers. Those systems are hardly ever used so there may be only 1 or 2 authenticates a day.
 
My concern is that the primary is running at around 30% cpu utilization constantly, and the secondaries are running at around 1%. Why the primary would be running the cpu that high when it should be pretty much idle most of the time? Or, how can I find out what process is running the cpu that high ?

Cisco WAN :: 2811 High Cpu Utilization

Apr 29, 2013

I have a 2811 that is really hitting the CPU hard.  Nothing shows on CPU processes.  It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN.  The HQ has 2-3 IPsec tunnels to other remote sites.  The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%.  The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps.  I read somewhere that its possible that fragmentation could be causing this.  My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites?  Siince they use the same outside interface to my HQ, is that correct?

Cisco WAN :: CPU Utilization Hitting 100% On 2621XM?

Dec 26, 2011

I am not sure if the issue I have is due to router's performance of my configuration. Currently I have 2621XM connected in my internal network where Fa0/1 is considered untrusted zone and Fa0/0 is considered trusted. It appears that traffic is limited to about 3.17MBps (Mega Bytes) between Fa0/0 and Fa0/1. There are ACLs on the Fa0/1 inbound and Fa0/0 inbound. I am also using ip inspect rules for the Fa0/1 outbound traffic. When I remove ip inspect policy from the Fa0/1 interface, the traffic speed bumps up to about 4.8MBps (which is about 38Mbps - Mega bits).
 
Each time the CPU utilization is: CPU utilization for five seconds: 99%/99%; one minute: 19%; five minutes: 4% PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process
 
Access to the router during that time is veerrrryyyyyy slow! Does this mean I am hitting the maximum limit this router can handle?

Cisco :: 5508 WLC - Getting MIB / OIDs For CPU Utilization?

Jun 24, 2012

We are finally installing 5508 controllers at multiple sites.  (Yaaaay) We have an existing SNMP mangement system (Zenoss) that will work fine with these 5508's if I can figure out which OIDs report things like CPU utilization, free mem, temp, number of clients etc.  We already have modeler plugins that list the number of APs managed and will also show the wired interface  stats.  Attached are two files with the resutls of snmpwalk. One has the raw OIDs, the other has the OIDs with the symbolic prefixes.
 
Most of that I'm looking for seems to be missing. For example, in other Cisco forum posts, it was mentioned that CPU utilization was available via this OID:

agentCurrentCPUUtilization ......OID: 1.3.6.1.4.1.14179.1.1.5.1

[URL]

and, Free Mem was available here:

agentFreeMemory      free RAM of in Kbytes ....OID: 1.3.6.1.4.1.14179.1.1.5.3
 
Problem is, none of those OIDs are returned when I walk the 5508. For example:

[ZenStatus]$ snmpwalk -Ofn -v2c -c M31eRt4 10.254.248.3 | grep -F "1.3.6.1.4.1.14179"
[ZenStatus]$

(nothing even close to the agentCurrentCPUUtilization OID is  found)We are currently running  7.0.235.0 .
