Create VLAN on a router

J_Maia
Level 1
Level 1

So I'm studying for CCNA exam, I was watching a instructional video that wants me to create a VLAN on a Cisco router, with the vlan <number> command in global configuration mode.

 

I'm using Cisco router 1921 (with a HWIC-4ESW module installed, that proves 4 ethernet ports) on Packet Tracer. Clearly I'm doing something wrong, but don't know what is it?

those guys take old way of vlan commands; when in doubt, always use ?

Router#vlan ?

database Configure VLAN database

Router#vlan 10

^

% Invalid input detected at '^' marker.

 

Router#vlan database

% Warning: It is recommended to configure VLAN from config mode,

as VLAN database mode is being deprecated. Please consult user

documentation for configuring VTP/VLAN in config mode.

Router(vlan)#

Router(vlan)#exit

APPLY completed.

Exiting....

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#vlan ?

% Unrecognized command

Router(config)#vlan

here is the guide for WIC switch module config :

 

https://www.cisco.com/c/en/us/td/docs/routers/access/interfaces/software/feature/guide/geshwic_cfg.html#pgfId-1107195

 

In general config :

 

ROUTER
========
!
interface gig0/0
no shut
!
interface gig0/0.10 <-- sub interface tagging to VLAN
Description Vlan 10
encapsulation dot1q 10
ip address 10.10.10.10 255.255.255.0 <<- example IP change as per requirement)


SWITCH SIDE Trunking
===============

confis t
!
vlan 10
!
interface Gi0/0 or FA 0/0 - change the interface as per requiremetn
switchport mode trunk <- this will allow all VLAN 1-4096)
!
! Tagging port to acces switch VLAN 10
!
interface Gi 0/1 -- where end device connected
switchport accesss
switchport access vlan 10

Than VLAN database seems to work, I can now create VLANS.

 

Maybe it's because the instructor of the video was using a 1921 switch? Can't select this model on packet tracer. He created the VLANS in Global config mode

 

my PT doesn't have 1921, only 1941,  I think 1921 was in older PT version.   as PT goes thru upgrades/updates of versions, new devices are added and some old are removed. Some commands work and some don't;  PT is just a simulator -not real thing.  overall, it does not matter as long you figure out what works or takes.

 btw. new PT 8 version is released !

I am now begining to think I should had started a video course where they only use packet tracer. Commands that he uses don't seem to work on my pc.

 

For example, I'm now trying to configure a trunk on a interface port, but the command "switchport mode trunk vlan" is not recognized.

 

EDIT: forget it, I'm a moron, I was selecting the wrong interface port

Many thanks for the help
