STP and Packet Tracer

mark076h

Packet tracer is pretty much worthless for STP commands. Looks like I am going to have to stop being lazy and use my lab lol.

I cannot do

show spanning-tree root

show spanning-tree bridge

debug spanning-tree events

heck i can't do anything!

I come across that aswell, packet tracer is useful for the CCENT exams. Buts nothings better than real equipment.

Yeah, there's only a few options available, it seems:

Switch#show spanning-tree ?
  active             Report on active interfaces only
  detail             Detailed information
  inconsistentports  Show inconsistent ports
  interface          Spanning Tree interface status and configuration
  summary            Summary of port states
  vlan               VLAN Switch Spanning Trees
  <cr>
Switch#

Just remember, Packet Tracer is an emulator, and is inferior to simulators, as well as the real thing. However, in my experience, these kind of things are easy to work around at the CCENT/CCNA level. Most students at that level do just fine with Packet Tracer, and maybe a little bit of work in GNS3 if you really feel compelled to have a full feature set.

But GNS3 doesn't have switching.

I believe you have it the other way around. Packet Tracer is a simulator. GNS3 would be an emulator. Here's a good example. If you play the SNES ROMs, you would have to play it on one of the SNES emulators, right? The emulator gives you nearly complete access to whatever features are available as opposed to a simulator, which only have limited features that the programmers enabled.

But I believe it can emulate layer-3 switching if you use the right router and IOS version, but it can be glitchy.

For example, you can use the switching feature using 3725 router with IOS version 12.4 and using NM-16ESW network module.

Here's the link: Layer 3 switching

Yea,the packet tracer does not support some commands and also it supports some commands that are not right,like in the real world or in the simulations on the test,if you are to configure default gateway on a switch you have to configure it globally but in the packet tracer it will accept configuring it on the int vlan1 mode which will not be accepted in real world or in the actual test.
