Unable to create more vlans in C3725

Hi,

As per titled, I have encountered errors while trying to create more than 4 vlans in a C3725 IOS using dynamips.

 

The error showed that the NVRAM space is not enough..Squeezing in process.

 

Can anyone advice me what should I do to resolve the above issue?

 

Many thanks.

    I am using this IOS

    Cisco IOS Software, 3700 Software (C3725-ADVENTERPRISEK9-M), Version 12.4(15)T7, RELEASE SOFTWARE (fc3)

    Your error is not bug or standard error faced by everyone. Can you try by chaing the IOS or setting idle-pc value?

     

  • Try erase and squeeze of flash:

    erase flash:

    squeeze flash:

    You will need to enter your VLANs again though.

    You could also try to save the VLAN.dat on NVRAM instead, use the vtp file command from global mode.

  • Hi

    Make sure after going through the above steps, you reboot the dynamips instance.
