Cisco Packet Tracer 1.1.7

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
The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.
There is a known issue between packet tracer 7.1 and Ubuntu 16.04 which blocks packet tracer from starting. Packet tracer needs a library libicui18n.so.52 which has been updated with libicui18n.so.55 in Ubuntu 16.04. To solve this issue, we have to download and install the older version of this library. Older version of this library is available in a Debian package at :-
Open terminal type packettracer, make sure you use two t's, packettracer not packetracer, not case sensitive, do not need to change directory, I am running version 7.1.1 on ubuntu 14.04, no need to type packettracer7 or packettracer7.1.1 just packettracer.
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.
The PTBridge java utilitary has been validated working with Cisco Packet Tracer 7.0 . This tool provides real network connectivity to Cisco Packet Tracer, and thus the ability to connect to other lab environments. Download it from Github and connect your Packet Tracer labs to your real Cisco devices !.

One of the more useful features in troubleshooting on the PIX/ASA (which we used until recently) is the packet tracer, which allows us to enter source/destination IP/port, etc and check to see if a given connection is allowed or blocked, and by which rule. Is there an equivalent feature in the PA units?
The Cisco ASA packet tracer allows you to propose a hypothetical flow and runs it through the engine as if it were real. Evaluating the NAT and route dicisions which would likely apply in addition to the policy/ACL allow/deny logic.
so for argument sake, say user on 10.10.20.111 is trying to connect to say 172.16.50.9 on port 443, but claims the firewall is blocking them. You can emulate that traffic. This is a vital tool for rule querying.
this is up to layer 4 of the OSI, which gives good details on: known route/path, NAT and whether there is a supporting rule. If the packet gets dropped, there is good information which points out where and why it was dropped. Which gives guidance on what needs to be added to resolve it.
