How to change the below default values in STP

[chandra_rc16]

How to change the below default values:

Hello Time  2 sec  Max Age 20 sec  Forward Delay 15 sec

             Aging Time  20

I'm not seeing any parameter indicating them in the root bridge.

Switch0(config)#spanning-tree vlan 10 ?

  priority  Set the bridge priority for the spanning tree

  root      Configure switch as root

  <cr>

Thanks in advance

Is this on real equipment? You should have options for forward-time and hello-time after you specify the vlan.... What platform is this?

This is a virtual software and is none another than PT.

Packet Tracer is still quite limited in what it can do. You could look into using the Cisco Learning Labs.

Yes PT have limitation about specific commands:

Here is the commands to change:

spanning-tree [vlan stp-list] max-age seconds

Interval the switch waits between receiving BPDUs from the root switch.

Enter a number from 6 to 200.

spanning-tree [vlan stp-list] hello-time seconds

Interval from 1 to 10 seconds.

spanning-tree [vlan stp-list] forward-time seconds

Forward-delay interval from 4 to 200 seconds.

Hope it helps.

The max-age setting must be greater than the hello-time setting.

So will PT help me to pass CCNA or not ?

Hi chandu,

PT is more then enough for CCNA.
But still if you Cisco devices then u can try with them.

Try some PT simulated question from Internet and try to solve them.
