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 :: Using SNMP To Monitor Bandwidth Utilization History ASA 5510

Dec 22, 2008

I matched the traffic statistics on one of my Cisco ASA site-site tunnels with the OID:1.3.6.1.4.1.9.9.171.1.4.3.1.1.25.4142 (cipSecTunHistInOctets).  I was real proud of myself for a few days until I checked the history and found the OID wasnt working.After some troubleshooting I found that the last four digits (4142 in this case) change whenever the tunnel drops and re-establishes itself. Any way to collect tunnel utilization history on an ASA with SNMP?  Is there a different OID I can use thats based on the endpoint IP?

Cisco Switching/Routing :: 3750Gs / MRTG Bandwidth Utilization Not Same As Sh Interface

Dec 19, 2011

The other day  3rd party supplier ran some stats on our Gigabit link between 2  Cisco catalyst 3750Gs.now the graphs produced showed only a Maximum output of about 100Mbps ( 5 minute intervals) yet when I do a show interface it shows a lot more always 150Mbps and more. So I did my own Perl script  doing an "sh interface" every minute and then graphed it, and the results were a lot different to the MRTG results.Questions: I know MRTG uses SNMP  to get the traffic  is there a bug in the SNMP, what OID does it use?does the "sh  interface" give the correct results?

Cisco WAN :: Aironet 1240AG - Setup Guest Network That Is Secure And Limited In Bandwidth Utilization?

Jan 27, 2013

I have a Cisco Aironet 1240AG Access Point and I am trying to setup a guest network that is secure and limited in bandwidth utilization. I see an option under security > SSID Manager on the web interface to select an interface of Radio0-802.11G, Radio1-802.11A or both. Can I put the guest network on the Radio1-802.11A and make it more secure/bandwidth limited or does this option not matter?

Protocols / Routing :: Measure Network Occupation Per VLANs

Jan 7, 2013

The question is apparently simple. A network is given, consisting of

- 1 network core switch: HP 5500-EI (Layer3)

- 4 access switches: HP 5120-EI (Layer2)

They are connected in the shape of a star (the core switch in the center)The task is to measure the occupation rate of this network on a per-VLAN basis.

For example : To be able to generate statistics like: During the last week - Monday to Sunday - the netowork occupation with VLAN 10 traffic was 30% and VLAN 60 traffic was 70%.

Cisco Switching/Routing :: 3750G / How To Measure Respond Time

Jan 29, 2012

How can I measure a respond time from a switchport to another? What I intend to do is to measure packets transmission from a server. I have a Cisco 3750G in stack, and the server is connecting to it with a 1GE NIC. How do I measure from Cisco prospective? Any tools available from Cisco to measure such respond time? I have a PRTG on bandwidth management on this particular server switchport and it is around 45-70Mbps, which is less than 10% of 1GE interface.

Linksys Wireless Router :: E4200 Best Way To Measure Actual Connection Speed

May 2, 2011

Soon my town will be getting fiber to the home, so I've already upgraded my home network to handle this. One of the changes is that I'll no longer use my powerline adapters to stream video, but to transfer the IPTV data. For streaming I wanted to switch to Wifi, so I bought the E4200 and compatible adapters and bridges (see subject).The powerline adapters have a bandwidth of 200Mbps, of which I get an actual 120. This works fine except for full 1080p, that stutters. The E4200 has a maximum of 450Mbps, but the adapters and bridge only do 300, but that should be sufficient. So after replugging my network, I tested it last night by playing a 350MB 45 minute episode of a TV series... And it stuttered!
 
Doing the math, that would mean the connection was less that 1Mbps! The WUSB600N and E3200 were (direct line) about 4 meters apart, separated by a concrete floor. What is the best way to measure the actual connection speed?And more important; since the E3200 does both 2.4GHz and 5GHz, how can I tell which band the adapter is using? I want to use the 5Ghz band, since that is fairly empty compared to the 2.4Ghz. However, I've configured both with the same ID, as the E4200 manual instructs, but I think it may be better to separate them?

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%.

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 :: 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.

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 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?
