Line Protocol down usually indicates the circuit coming into the router is down. You can try going into admin mode and do a shut - no shut on the interface. If it doesn't show UP-UP after that, I would call your circuit provider as it's prob something they need to address.

When I enable the vlan option in an EAP9550 I lose wireless access


Bruce,

Is the goal to use a different VLAN for each access point (AP)? If so then you will need to configure each NetGear port to use the same VLAN as the AP that is connected to it. You will then need either a switched virtual interface (SVI) for each VLAN on the NetGear or a trunk port (802.1q) from the NetGear to the Cisco. I'm not sure the NetGear will support SVIs but it will support trunks. An SVI basically creates a gateway for each VLAN's subnet. For example, let's say AP1 uses VLAN 10 and the subnet is 10.0.10.0/24 while AP2 uses VLAN 20 with a 10.0.20.0/24 subnet. The NetGear will need 2 SVIs, one for each VLAN/subnet. The first SVI for VLAN 10 can be configured with IP address 10.0.10.1/24 while the second SVI can be configured with 10.0.20.1/24 for VLAN 20. These IP addresses will be the gateway for each VLAN. Finally, the NetGear would need to act as a router and route each VLAN's subnet to the Cisco device. Once again I don't believe the FS726TP supports this.

The other solution would be to create a VLAN trunk port between the NetGear and the Cisco device but I believe the Cisco RV042 does not support trunking. If it does the trunk would be configured to carry all of the VLANs to the Cisco device which would then have SVIs created on it.

If neither of the above is possible you would need to use the same VLAN for each AP and each of the interfaces on the NetGear and Cisco devices which negates the need for the VLANs.

I hope this helps.

Hello, I have a Linksys SRW2016 and 2048 switches with one cisco 1800 series router. I have successfully created two vlans on one switch and when i try to connect a trunk port to cisco router it...


Make sure that the frame encapsulation is set on the router to 802.1q on each of the sub-interfaces. You could also try fixing the speed and duplex on both the router and the switch in case there is a problem negotiating the speed and duplex.

Hope that helps!

I have the Dlink 1700 series router i need to add in 2vlan.its possible


Usually you can create VLANs on routers. On cisco 1700 (based on ur image) you can create multiple VLANs.
If you can give me the exact model number on dlink i can help you to fix the problem.

ZyXEL IES-1000 with AAM1212 ADSL 12 port module step-by-step guid


Going through the GUI would take too long, so use CLI to add the commands below. After that, check the GUI and see how those changes appear.

VLANs:
On all equipment use 802.1q tagging. The example below puts adsl ports 1 to 10 in vlan10 and ports 11-12 in vlan2. These vlans are 802.1q tagged on the ethernet ports.

switch vlan set 1 1~12:X enet1~enet2:FT DEFAULT
switch vlan set 2 1~10:X 11~12:FU enet1~enet2:FT VLAN2
switch vlan set 10 1~10:FU 11~12:X enet1~enet2:FT VLAN10
switch vlan set 17 1~12:X enet1~enet2:FT VLAN17
switch vlan pvid 1~10 10
switch vlan pvid 11~12 2
switch vlan pvid enet1~enet2 1
switch vlan priority * 0
switch vlan gvrp * disable
switch vlan frametype * all
switch vlan cpu set 1

ATM circuit:
Each port requires one or more VPI/VCI circuit. You could map different circuits to corresponding vlans. The config below creates a primary circuit 1/35 on each port. On ports 5 and 9 is another circuit 1/32 mapped to vlan10

adsl pvc set * 1 35 super DEFVAL
adsl pvc set 5,9 1 32 10 0 DEFVAL

Remember a dslam is just a switch, bridging packets from a VC onto a VLAN or straight onto ethernet.

Sending DHCP request across diffrent vlans


Hmm... on your DHCP server, try setting the "default router" IP for each pool to be the VLAN ID on the switch.

scope 172.16.0.0 /24
router 172.16.0.1

scope 10.20.8.0 /22
router 10.20.8.1

I think the DHCP replies aren't going back where they should. I've never done this without a router doing all the DHCP, but it does work and i've done it many times. Your config looks spot on for the switch.
