Packet Tracer 5.1 Setup Free
Brandi Baylon
Coming from an ASA back ground I am trying to learn more about troubleshooting in the PA. From what I learned so far there is no command in the PA that tests the full path of communication similar to packet-capture in the ASA. When in CLI I see there is a test command that breaks out different components of the communication path. I can test routing & policies which is great. Does anyone have a method they use to test different components of the full communication path? Are there certain things to test in an order? We are going to turn on all next gen features & I want to be prepared for request to troubleshoot why a host cannot access resources outside their own zone & there could be a lot of potential reasons not just layer 3 & 4. Thanks.
The only thing you need is logs. Enter filters for the session in question and look for any blocked events. Either in each log file seperately (traffic, threat, URL..) or in unified logs. Especially with threat logs keep in mind that source/destination of an event doesn't necesarilly match the direction of session.
So will logs show every & any specific reason why a session between 2 hosts cannot be successfully connected? From a firewall perspective of coarse. For instance if someone on the internet can't get to my web server because I don' I have NAT set up at all or it is not set up correctly.
You would see the traffic hit the Public IP address and then see it either 'age-out' or hit the interzone-default rule. Looking at the associated session ID will show you that it didn't complete a NAT process.
There is nothing directly compariable to Packet Tracer on the Palo Alto. You'll kind of have to force that out of your mind and just focus on how to actually troubleshoot Palo Alto equipment. The logs will give you everything you need to know, and the test commands will allow you to test the policies and ensure that it'll actually hit a NAT policy, or a Security policy, or any of the like as you put something into production.
The 'test' commands should just be worked out as part of you deployment process. I have this new website/service and I've completed the NAT and Security rules; does the 'test' statements show that the traffic will match the expected NAT rule, does it show you will match the expected Security rule? There isn't anything as 'full-featured' as packet tracer.
That could just be the subnets you need to make but not necessarily need to add on the simulator. Like @MHM Cisco World said as long as you have 1 or 2 devices per subnet to test reachability it should be fine. (but also clarify with the instructor if you can) If it says you need 30 hosts in this subnet and 12 hosts in another, instead of putting 42 hosts in packet tracer you would just need to create the networks that can support that many devices and the couple of devices you add would just have IPs from that subnet with a default gateway and such.
which version of Packet Tracer are you using ? If you use the scroll bars at the bottom and right, the UI is rather large, and (at least in version 8.1.1) I can fit hundreds of devices. Can you post a screenshot showing the small UI you have ?
to emnoc: people are not locked to cisco approach, just want to use good inventions if its possible. Imagine i have remote site, like datacenter , and no users can help me to generate traffic but i want to test web filters and app filters under policy , i have report that access to box.com and dropbox are passing trough although i see web filter block is applied for file sharing and storage category. How can i test at this situation? Where i'd get "active" traffic in datacenter with no users there?
Actually fortios has added a packet tracer like function to fortios "diag firewall iprope lookup" it can do protocol and port traffic flows and show you want policy is matched. you do not need active traffic per-se

Packet tracer is fairly limited. It is designed to let someone practice for the CCNA exams. It doesn't include all the IOS features, only a subset of commands that are useful for CCNA-level exercises.
I am using a ASA5510 and configured it using ADSM. I have an external internet gateway with is my default route (0.0.0.0) metric 2. And I have an internal subnet with my machines. All these machines use dedicated NAT per machine. Everything works fine.
I need to reach another IP range behind that subnet and I added another static route to this subnet on that interface. It appears to be right as I can see my traffic is now blocked from that interface.
I have added a ACE on that interface to allow any any ip, to test. When I use packet tracer it says the packets are allowed. But when I for example try to ping the next hop (not the bridging subnet) I see in the event log that the packet is denied.
I would like to know if anyone on this forum has found packettracer installation package for Rocky?
I have looked around but cannot find it though snap searches on snap craft but not installing it.
The easiest way to get Packet Tracer (and the official one) would be to register at netacad.com and download packet tracer deb. The easiest way I can think of is a virtual machine with Ubuntu 20 running just for Packet Tracer.
thank you for help. I have another homework with other problem I have three routers and I can not ping the third router however I configured ipv6 static routing. please help me thank you, frank.
by the way how can link or post my packet tracer file?
What are you routing to and from, on each switch? When I did this last (which was more than 12 years ago), it was just a case of configuring the default gateway for the first router, and static routing for the second one, so that specific routes would go down the second one, everything else down the first. Exactly how you configure that will depend on the router and the operating system running on your other devices.
Update 06/04/2024 : A new Cisco Packet Tracer 8.2.2 version has been released for download on Netacad website. This is a bugfix release fixing several bugs on accessibility, usability, and security of Packet Tracer 8.2. Cisco Packet Tracer 8.2 introduced a new command as well as bug fixing regarding incompatible DLLs that caused Packet Tracer crashes.
Cisco Packet Tracer 8.2 is created by Cisco SystemsTM and is provided for free to everyone. Self learners are able to download Cisco Packet Tracer after registering on Cisco Netacad website. This is a major change in Cisco delivery policy for Packet Tracer as previous versions were only available for Netacad students and instructors.
Cisco Packet Tracer 8.2.2 can be downloaded for FREE from official Cisco Netacad website. Log in to Cisco Netacad.com learning website and select Resources > Packet Tracer in the menu to access the download page. The software is provided with several tutorial files allowing academy students to discover the software features.
The NX-OSv 9000 is a virtual appliance designed to simulate the control plane of a Cisco Nexus 9000 switch. The NX-OSv 9000 shares the same software image running on Cisco Nexus 9000 hardware platform. Line card (LC) ASIC provisioning or any interaction from the control plane to rela switch ASICs are emulated by the NX-OSv 9000 software data plane.
Following the the Nexus 7000 Titanium emulator, the NX-OSv 9000 is a moder emulator for datacenter certifications training. It's also great plaform to test network automation prior to production deployment.
NX-OSv 9000 runs on GNS3, KVM, or VMware NSX. Current version of NXOSv is 10.4(1)F. This version adds or enhances VXLAN EVPN First Hop Security (IPv4), radius over DTLS, port-channel load-balance command for MPLS tagged traffic, support to redirect/deny all packets using ePBR policy, VXLAN QoS Outer Header Policy for Layer 2
UCS PE (Platform Emulator) is a powerful Cisco UCS Manager emulator allowing CCNP datacenter students to learn how to configure the UCS environment. The current version emulates the UCS manager 4.2(2aPE1), which includes 62xx/63xx/64xx Fabric Interconnect, C4200 series rack server chassis with C125 rack servers, as well as Cisco UCS M6 and HX220C and HX240C servers support. The S3260 storage server is also emulated in UCS PE. These release can be connected to GNS using VMware.
UCS PE is also featured in a Cisco dCloud programmability demo (cisco login required). The demo includes a comprehensive lab guide including the following content for Cisco UCS PowerTool and the Python SDK:
PT Anywhere is a web application designed to offer a network simulation environment based on Cisco Packet Tracer engine throug a web interface which can be accessed from a web browser. PT Anywhere can as such be integrated inside a website, an online course, a learning systm like moodle... It has been developed by the Open University and Cisco and has been funded by the FORGE project.
