SOURCE: 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.

SOURCE: I want each vlan member to get different ip address scope.

I believe it is possible to do this, judging from briefly looking at the reference documentation, although I'm not entirely certain.
Here is a link to the documentation.

SOURCE: Hello,

On the linksys switch set the trunk port connecting to the cisco to 'general'. Match the native vlan on the linksys switch port with the cisco. The native vlan on the linksys will be set to 'untagged' with any other vlans that you want passing over the trunk set to 'tagged'.

You probably have a good grasp of how to do trunking on the cisco. The linksys does it, lets say, differently.

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.

Cisco asa 5500 - sh interface - reveals switch ingress policy drops - what are these ? will they slow down traffic ?


The following is an excerpt from cisco.com defining policy drops and their possible causes:

This drop is usually seen when a port is not configured correctly. This drop is incremented when a packet cannot be successfully forwarded within switch ports as a result of the default or user configured switch port settings. The following configurations are the likely reasons for this drop:

blank.gifThe nameif command was not configured on the VLAN interface.

Note blank.gifFor interfaces in the same VLAN, even if the nameif command was not configured, switching within the VLAN is successful, and this counter does not increment.

blank.gifThe VLAN is shut down.

blank.gifAn access port received an 802.1Q-tagged packet.

blank.gifA trunk port received a tag that is not allowed or an untagged packet.

blank.gifThe security appliance is connected to another Cisco device that has Ethernet keepalives. For example, Cisco IOS software uses Ethernet loopback packets to ensure interface health. This packet is not intended to be received by any other device; the health is ensured just by being able to send the packet. These types of packets are dropped at the switch port, and the counter increments.

blank.gifThe VLAN only has one physical interface, but the DEST of the packet does not match the MAC address of the VLAN, and it is not the broadcast address


Throubleshoot these and see if any of them apply to you. Thank you for choosing fixya.com.

I am in a need to block my port 8080 traffic over some ports of my link sys sd 216, how could i access these ports is there any specific software to do so.


According to the documentation, The Cisco SD216 does not have any port blocking capability. It's just a simple unmanaged switch. Ports are usually blocked at a router or firewall.

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!

How can I change the default management vlan (vlan 1) to another vlan # in Cisco Aironet 1242G wireless AP

then ensure that the ethernet port is the same bridge group number as the new vlan (bridge-group 10)
do the same for the wireless port

then shut down vlan 1

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.

Cisco error on switch


%SYS-4-P2_WARN: 1/Tag 0 The switch generates %SYS-4-P2_WARN: 1/Tag 0… messages.
This example shows the syslog output that you see when this error occurs:
%SYS-4-P2_WARN: 1/Tag [dec] on packet from [ether] port [chars],
but port's native vlan is [dec] This message indicates that an 802.1Q-tagged packet was received on a nontrunk port. The VLAN that is derived from the packet tag is different from the port native VLAN. In the error message:
  • The Tag [dec] is the VLAN identifier from the packet.
  • The [ether] is the host MAC address.
  • The port [chars] is the port identifier.
  • The second [dec] is the native VLAN number.
There is a possibility that the local port is incorrectly configured as an access port instead of a trunk port. Alternately, the remote side can have been configured as a trunk port instead of an access port.
Verify that the local port is not incorrectly configured as an access port instead of a trunk port. Also, verify that the remote side is not configured as a trunk port instead of an access port.
