The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

CISCO 871 - Problem to configure VLAN

Asked by rafaeldemartin in Network Routers

Tags: vlan, cisco, 871

I have a router CISCO 871 (4 fe ports and 1 wan port) and I want to configure new VLANs. I have this configuration in my router:
...
!
interface FastEthernet0
!
interface FastEthernet1
!
interface FastEthernet2
!
interface FastEthernet3
!
interface FastEthernet4
 description $FW_OUTSIDE$$ES_WAN$$ETH-WAN$
 no ip address
 no ip redirects
 no ip proxy-arp
 ip route-cache flow
 duplex auto
 speed auto
 pppoe enable
 pppoe-client dial-pool-number 1
!
interface Vlan1
 description $ETH-SW-LAUNCH$$INTF-INFO-HWIC 4ESW$$ES_LAN$$FW_INSIDE$
 ip address 192.168.0.1 255.255.255.0
 ip access-group 100 in
 no ip redirects
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly
 ip route-cache flow
 ip tcp adjust-mss 1452
!
interface Vlan2
 ip address 192.168.100.1 255.255.255.0
 no ip redirects
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly
 ip route-cache flow
 ip tcp adjust-mss 1452
!

...

When I try to configure VLAN2 to fe2 I receive the following error:

router(config)#interface fastEthernet 2
router(config-if)#switchport access vlan 2
%Access VLAN 2 does not exist. Please add it to vlan database


When I try to add the vlan to database I receive the following error:

router#vlan database
router(vlan)#vlan 2 state active
Vlan can not be added. Maximum number of 1 vlan(s) in the database.

or

router(vlan)#vlan 2 media ethernet name VLAN02
Vlan can not be added. Maximum number of 1 vlan(s) in the database.

The router CISCO 871 supports 4 VLANs and I don't know where I'm making the mistake!

This is another configuration I have in my router in vlan:


router(vlan)#sh
  VLAN ISL Id: 1

    Translational Bridged VLAN: 1002

  VLAN ISL Id: 1004
    Name: fddinet-default
    Media Type: FDDI Net
    VLAN 802.10 Id: 101004
    State: Operational
    MTU: 1500
    Bridge Type: SRB
    Bridge Number: 1
    STP Type: IBM

  VLAN ISL Id: 1005
    Name: trnet-default
    Media Type: Token Ring Net
    VLAN 802.10 Id: 101005
    State: Operational
    MTU: 1500
