Cisco Firewall :: ASA 5510 7.2.1 High Traffic On Outside Interface Very High Input?

Oct 13, 2011

Today I've received reports of slow internet access/activity and have noticed myself that it seems a bit slow today.  On the dashboard of our asa 5510 the "outside interface" traffic usage is running constantly high. It's at the top of the graph. How can I tell what is causing the spike in utilization. It usually runs at about 1500-2000 Kbps, and now it's up over 10,000.

Cisco Firewall :: Mask DMZ Servers From Private Servers And LAN ASA 5520

Jun 11, 2013

We are planning to split the Private servers from the DMZ Servers and configure an additional Interface and segment for this purpose.
 
Private Servers Segment: 192.168.4.0/24 (there is no DHCP all servers' IPs are statically configured)
DMZ Segment: 192.168.3.0/24 (This is a future deployment)
LAN Segment: 172.17.0.0/16
 
Both, Private Servers and DMZ Servers are in a collocation as well as the ASA5520. There are multiple Branch offices that uses subnets within the 172.17.0.0/16 Network and they are connected to the ASA5520 via Metro-E.
 
I do not know if this is possible but what I want to do is this:
 
In order to avoid the change of internal DNS records I want to mask the DMZ servers with a Private Server IP when a Private server or LAN host wants to access it like this:
 
The FTP server in the DMZ has the IP address: 192.168.3.100. But when a PC from the LAN wants to reach the FTP server it should points to its old IP: 192.168.4.100. This way the PC sends a packet to the ftp.corporate.net (192.168.4.100) the ASA recieves the packet and translate it to the (192.168.3.100) and send it out through the DMZ Interface.
 
Also if the Private Servers wants to reach the same FTP the ASA will act like a proxy-ARP and send the paquet to the DMZ by means of the translation of the IP.

D-Link DIR-825 :: Allow Request / Renewal Through UDP Port / Cannot Reset DIR-655

Nov 3, 2012

I have just bought a DIR-825 rev C1 stock firmware 3.0 (19 Jan 2012,) and I am pleased with its performance so far. However, I need to allow DHCP renewal request to pass through from all IP to UDP port 67 to UDP port 68; or else I will have to reboot DIR-825 every 24 hours (which is not fun ). My U-verse 2wire modem is a 3600HGV.

Cisco Firewall :: 5505 PAT With Single Public IP And Several Servers Behind Firewall

Nov 21, 2012

New to the ASA 5505 8.4 software version, but here is what I'm trying to do:
 
-Single static public IP:  16.2.3.4
-Need to PAT several ports to three separate servers behind firewall
-One server houses email, pptp server, ftp server and web services: 10.1.20.91
-One server houses drac management (port 445): 10.1.20.92
-One server is the IP phone server using a range of ports: 10.1.20.156
 
Basically, need to PAT the ports associated with each server to the respective servers behind the ASA 5505.  Is anything missing from this config? Do I need to include a global policy for PPTP and SMTP? [code]

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 WAN :: 2801 High CPU Load / Low Traffic / High Interrupts

Nov 26, 2012

We installed a solution with 2 Cisco 2801, BGP multihomed failover.
 
1) The router which is currently getting all the traffic gets to 55% to 60% of CPU usage when handling 40 SIP/RTP streams . This equals 10Mbit up/10Mbit down and it showed around 5800 packets TX and around 5800 packets RX, with a majority of them CEF switched. As those figures are way less than the performance figures published by Cisco, we wonder if we made any mistake in setting up our router, or if we can do something to improve the router setup.
  
2) Does it have an impact on router performance if we increase/decrease RTP packet size, thus increasing or decreasing the pps relative to the consumed bandwidth?
  
3) If it is not possible to improve router configuration, we also wonder about possible replacement units for those routers. Would a 2901 do a good job? By how much would it rise the capacity? What other models would you recommend if we plan to rise the number of concurrent calls by a factor of 4 or even 8 times of what we have now (so up to 48000 pps and 80Mbit).
  
Here is what we tried:

- ip route-cache same-interface does not seem to improve anything

- ip flow ingress on or off makes no difference

- disabling the inbound ACL on fa0/0 seems to reduce load by 10%, although I don't understand why - a very high percentage is CPU interrupts, and ACLs are process switched, or not?

- we tried following the Cisco guide for high CPU due to high interrupts, with no success
  
Here are some usage statistics: 
 
The graphs that we plot via SNMP show a propotional growth/increase of CPU and bandwidth (and thus pps) At the highest loads, we had a bit more than 55% CPU utilization with more than 50% interrupt CPU.
 
CPU utilization for five seconds: 36%/30%; one minute: 30%; five minutes: 30%
PID Runtime(ms)     Invoked      uSecs   5Sec   1Min   5Min TTY Process
127       13140         954      13773  2.00%  0.29%  0.07% 194 SSH Process

Cisco Firewall :: 6509 / High Connections On FWSM?

Oct 19, 2011

I am having issues trying to track down what is causing a high number of connection on our FWSM in our core 6509 switch. I recently upgraded my FWSM to 3.1(20) and I'm looking for a tool to be able to find the culprit. When I receive these messages I try to get onto the firewall in time to be able to get information regarding this issue but by the time I do the device recovers. Is there a way to tweat the threshold of the SNMP trap for high connections? Is there any way I can retreive this information via SNMP? Is there are command that will allow me to extract the local IP making the most connections?

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?

Cisco Firewall :: Dispatch Unit High CPU ASA 5550

Jan 29, 2012

I'm trying to do some research on the Dispatch Unit process.  It seems High CPU and this process go hand in hand.  I haven't figured out an effective way of determining what underlying issue is the actual source. How to understand what the Dispatch Unit process is doing?  I have an ASA 5550.  I have seen the cpu hover around 85% +- 5% for sustained long periods, 30 - 60 min +.  I have always been under the impression that around 80% cpu and you're probably dropping packets (that could be an out-dated belief).

Cisco Firewall :: High Memory Utilization On ASA 5510

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 :: ASA 5520 High Availability Licensing

Mar 20, 2011

A customer is currently running a 5520 ASA pair in active/standby HA mode. The devices also have an IPS module, one of them using a temporary (60-day) license.  So, right now, licensing is identical on both ASAs and HA is operational.
 
The question is what exactly will happen after 60 days, once the temporary license expires?  Does HA shutdown completely once it's determined that the licensing isn't a 100% match any longer, or does it just cripple one feature (such as the IPS module)?
 
The customer is balking at purchasing SMARTnet for the 2nd ASA, so I need to explain exactly what is going to happen (if anything) once the license on the 2nd ASA drops off...

When we came in today we noticed the csc module cpu is running at 100% constantly and http traffic is extremely slow. I have not yet received my smartnet contracts from the vendor or I would open a TAC case and I have read on the net that this is a common problem.

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)?
