road to ccie with dynamips

Filed under: dynamips — ocsic @ 13:48

I came along some topics that do not work with dynamips and that have to be covered with other devices for training. The only problem is with 3560 specific features that are not availble on the NM-16ESW:

  • some optional available STP features, like bpduguard, bpdufilter
  • MSTP
  • layer 3 port-channel
  • different etherchannel protocols, a channel-group can only be turned on, no lacp/pgacp
  • private-vlans
  • sdm modes
  • udld
  • port security
  • port protected
  • qos specific configuration of hardware queues like srr-queue
  • port configurations like dynamic, desirable
  • some configurations are similar but do not look the same like on the 3560, for example vlan config, on the NM-16ESW there is only the old vlan database mode available
  • vtp transparent mode with vlan numbers from 1006 – 4094. Dynamips only knows about 1005 vlan numbers also in transparent mode, some workbooks might ask for vlan numbers greater than 1005, what then indicates that you have to use vtp transparent mode

Other features that are not only switching dependent

  • clocking feature for serial lines (no need to set up „clock 64000“)

There are probably other features to add here. I will keep up completing this list.
