Question

Problem with cisco 871 wireless on SMC 2554 AP's

Asked by: ibtaya

On my cisco 841w I am offering 2 ssids.  Vlan1 is my Open ssid and dhcp is terminated on the cisco device.  Staff is Vlan10 and dhcp is offered from my internal network.  I have all my SMC 2552 and SMC 2554's plugged into the same switch in the network room and going into port Fa2 on the cisco 871.  Where the SMC's are located they are plugged into little 5 port switches that local computers are also using to get to the network.  My assumption is that since they are both needing vlan 10 this should work but in fact the local computers are not able to get to the network whereas the wireless users on the staff ssid are able to get to the network.

You need to make thsi change:

interface FastEthernet2
 switchport access vlan 10
 switchport mode access

This change will allow your FA2 port to be on VLAN 10

 

by: ibtayaPosted on 2009-08-31 at 07:06:55ID: 25222877

but if the port is in access mode as apposed to trunk mode will it not block vlan1?

 

by: CanalInsPosted on 2009-08-31 at 07:09:39ID: 25222898

Help me make sure I understand what you are trying to pull off.

You have access points that need to access 2 VLANs 1 & 10

The access points are plugged into 5 port switches along with PCs. Your PCs need to be on VLAN 10

Are the 5 port switches managed switches?

 

by: ibtayaPosted on 2009-08-31 at 07:11:10ID: 25222909

the 5 port switches are not managed.  yes the ap's need access to vlan 1 and vlan 10.

 

by: CanalInsPosted on 2009-08-31 at 07:17:10ID: 25222967

Ok. If your 5 port switches are not managed they will not be able to participate in both VLANs. If your APs are allowing users on both VLANs successfully I would say that this is a good sign that the unmanaged switches are at least forwarding your 802.1q VLAN tagging.

The rest of the ports on the 5 port switch will only access a single VLAN.

You will need the uplink port on your Cisco router to be in trunk mode for your APs to work on both VLANs

You will need to select an unmanaged switch for each VLAN and uplink it to a port on your Cisco that is in

switchport mode access
switchport access vlan x

If you cannot upgrade your 5 port switches to managed switches I think you will need 3 ports on your Cisco router.

1 - VLAN 10
1 - VLAN 1
1 - Trunked for APs
