    L3 Ether channel in NM-16ESW (Dynamips GNS3)

    Naren

      Hello All,

       

      I'm practicing the INE CCIE routing and Switching Vol 1 using Dynamips.

       

      I use 3725 with NM-16ESW to  simulate the switch.

       

      I understand the limitation in this.

       

      But, could some one please clarify if I can create a L3 etherchannel using NM-16ESW module?

       

      Because the command "channel-group 1 mode on" gets unrecognised if i put it under a rotued port (by using "no switchport")  on NM-16ESW.

       

      In the same time, on the same port, the command goes in well if I configure it as L2 switchport.

       

      Please clarify if it is the limitation of NM-16ESW or dynamips. Can't it support L3 ether channel?

       

      Many thanks in Advance !

          You can't create a L3 Etherchannel with the NM-16ESW.

          Here is a list of what is missing with the 16 port switching module (NM-16ESW) for the 3725 in comparison to the 3550/3460 Catalyst switches in the CCIE lab.
