in CCNP
hello guys,
i am using gns3 for ccnp labs. i am using router as a switch.
i have added NM-16ESW in slot 1 of Router 3700. it has got 16 fastethernet interfaces.

it shows other configurations of switch. but when i try to create a vlan in it, it doesnt support this command ? does anyone know how to create vlans here ?

    yeah creating and managing vlans is slightly different, so keep that in mind. to configure vlans you have to be in normal enable mode.

    Router#vlan database
    Router(vlan)#vlan 10 name test_vlan
    VLAN 10 added:
    Name: test_vlan
    Router(vlan)#exit
    APPLY completed.
    Exiting....
    Router#sh vlan-switch

    VLAN Name Status Ports
    ----
    1 default active Fa0/0, Fa0/1, Fa0/2, Fa0/3
    Fa0/4, Fa0/5, Fa0/6, Fa0/7
    Fa0/8, Fa0/9, Fa0/10, Fa0/11
    Fa0/12, Fa0/13, Fa0/14, Fa0/15
    10 test_vlan active
    1002 fddi-default active
    1003 token-ring-default active
    1004 fddinet-default active
    1005 trnet-default active

    Keep in mind that vlan database mode is deprecated and will be going away at some point, so don't get too comfortable with it

    actually i am studying IP multicast and here some configuration of switch is required, so thats why i am using router as a switch in gns3 ?


    can we use this router as a switch in bcmsn ?
    i will be starting it soon, so would like to know that can we do all configuration required here ? or a seperate switch is required ?

    BCMSN tests on layer 3 switching, and GNS3 doesn't emulate switching all that well. You're better off getting your hands on a 3550 and practicing with that.

    Yeah I use the vlan command in global config.
