Cisco Switching / Routing :: WC2948G - Configure LACP Trunk And Multiple Trunk
Feb 12, 2012
we recently aquired a managed services job and have to do a overhaul of the vlan configs and have a whole dozen WC2948G's trunk between a set of ports as well as trunk out a LAG channel setup to non cisco equipment. the deal is the lacp-channel works properly on both ends but no routing of vlans between ports and between the lag trunk are working.
theres alot of settings in the config and im planning on clearing it and starting from scratch but before i do i want to know where my problem lies.

We have 7 3560's in 7 different locations connected to our providor for wan access. Our provider has given us a copper cable at each point and we have connected it directly to our 3560 switch at each location. Each port is configured the same way at each location. Each switch is running eigrp.All of the switch ports on each switch are configured as a trunk and vlan 299 had the ip address for the eigrp connection: [code] This setup is working as each switch see's all of the other switches as an eigrp neighbor. We have also made sure that the switch at our head office has spanning tree priority for vlan 299.
So the problem is, if there is a change in the topology at one of the locations it usually causes one or more of the other connections to go down for some reason. We just cannot pinpoint what is causing this change. There are no log's or anything other than an eigrp hold time expired message.?

I have just configured up a sg500 with a lacp trunk to an upstream switch.
I am getting native vlan mismatch on the individual ports of the lacp team.

Is there really any reason why you wouldn't use spanning-tree portfast on a trunk port other than a trunk between two switches? We have it enabled on all ports except for the fiber trunk between two non-stacked switches and the trunk ports connected to our Astaro firewall.I'd like to enable it on the ports to the firewall unless that would cause issues.

I have two WAP200's code level version 2.0.4.0 connected to two SFE2000 24port, one switch per building. I have 3 vlans that I want to bridge between those two switches. I know the trunks on the switch are setup correctly because I can connect them directly and test all vlans.
I am able to get the untagged Vlan 1 to work fine with the bridge, but I have issues with the tagged Vlans 2 and 3. I have checked that I have the correct SSID tied to the correct Vlan number. I cause the whole network to lock up when I try to add the other SSID MAC addresses to the AP Mode -> AP Mode -> Wireless Bridge -> "Remote Wireless Bridge's MAC Addresses:" section. The wireless lights and ethernet lights go solid.
Should I be adding the additional MACs there?Does the WAP200 even support multiple VLAN/SSID?

We have purchased 3 no CISCO SF300-48P (Access Switches) with the interest of setting up a new laboratory consisting of 120 desktops. We currently have a CISCO 4507R (Core Switch) and a CISCO 3560 (Distribution Switch) for the campus wide network. Our network is developed with various VLANS to support Internet and Intranet facilities. The new lab need to be incorporated in to the Campus wide network with a new VLAN ID. But problem is while trunking the CISCO 3560 (Distribution switch) to the CISCO SF300-48P (Access Switch) communication does not happen. While, surfing the internet and various doc's say that SF300 uses GVRP instead of dot1q trunking.

I currently have an 867vae router and a 1131ag ap setup with 2 vlans and 2 ssid's. I am in the process of baby proofing the house and would like to use the cisco plsk400 homeplug system to relocate my wap. I use 2 networks to seperate and filter the kids internet traffic from my own. It also allows me to shut the kids vlan when they shouldnt be on the internet.
As far as i can tell the plsk400 homeplug doesnt support 802.1q.... so is there any way i can keep the seperate networks/SSID's and the abilty to filter and turn off one of them at will without a trunked link to the router?

We have setup a pair of Nexus 5596 L3 switches with 2 x 10Gbps LACP links between them to act as the vpc peer link. We also have another 2 x 10Gbps LACP links between the 5596 switches to carry non VPC VLANs, this is required to provide EIGRP routing between the switches and an upstream router.I have read that it is possible to setup the vpc keep-alive link over an SVI instead of the management interfaces. Is it ok to run the keep-alive SVI over the second LACP non VPC VLAN trunk or is it recommened to keep this seperate?

I have 2 hosts, 1 plugged in fa 0/21 in VLAN 101 and another in fa 0/22 in VLAN 101 on our L2 Cisco 2960. If I try and transfer files from either host the gig 0/1 trunk port on the 2960 leading tot he 3750 fa 0/1 port hits 100mb (using a real time bandwidth monitor tool), but why? This VLAN is on the same switch, why does it go one way up the trunk to the L3 3750 switch? The L3 3750 is the VTP server and the 2960 is a client. I would of thought the traffic stays local. The 2 hosts don't even have a gateway set.To sum up the typology the 2960 and 3750 are trunked using a single cable. The 3750 hangs of a ASA firewall using SVIs.Here is whatthe traffic looks like when copying a file between hosts (2gb file).
3750 L3 Switch (VTP Server)
interface FastEthernet1/0/4
description Trunk to Cisco 2960 Gig 0/1

I have 2 Cisco 6509 switches linked together via single Fibre as a trunk.I want to change this to a port channel where I will add another 3 fibre ports to the port channel but what order do I do this to minimise any disruption.
1-Configure PortChannel and add the 3 new ports, this will bring up the Port Channel but what effect will this have on traffic currently going over the single Trunk link? Will spanning tree go mad, how will switches react?
2-Convert existing Trunk link to Portchannel then add in new ports to PortChannel, I guess in doing this there will be a small hit on traffic as it changes to a port channel.

I am struggling with a CE520 and its smartports stuff.I have configured the following vlans :
1- data
100 - phones
I need to bring those vlans (both of them) to a Cisco 800 router. The port of the 800 router is already configured as trunk and accepts vlan 1 and 100.The cisco 800 has both vlan 1 and 100 configured with 2 ips on different subnets, and ip routing is enable (to route between two vlans). Also, no access lists are configured.I have configured one port in the switch as role "router" and connected to the router. The other ports are all configured as phone-desktop (phone vlan 100 desktop vlan 1).If I connect a phone and manually configure an ip (the phone gets automatically vlan 100), and try to ping the phone from the router, it doesnt respond. Alse vlan 100 is protocol down.I am guessing what s the right configuration as the link between the switch and the router should be a trunk link for 1 and 100 vlans, but it looks like is transporting only vlan 1.Also changing the port role to "other" when you can specify the native vlan and another vlan, the switch doesnt accept vlan 100 as additional vlan on that link.

I need to set QOS in our new network. We have connected 2 cities together with 700Mbit leased line. On each side we have Catalyst 2960S switches and between them is TRUNK for VLAN 10 and Vlan 20.Vlan 10 is for IPTV (fixed 400 Mb/s for CATV)Vlan 20 is for Internet (rest).Sometimes is happening that Vlan 20 takes more than 400 Mb/s for a few seconds and in this situation we have problems with CATV.Is there any way to make a guaranteed bandwidth 410 Mb/s for CAT - VLAN 10 on this swithces?

I need to create a trunk between a Cisco 3560 and a Juniper EX4200I am perfectly happy with the the Cisco side and want to only allow 1 vlan across the trunk, which I was going to configure on the 3560 side. Any experience on trunking to a Juniper Ex4200.Looking at the Juniper side it looks like I just set the port as a L2 uplink.

I have a couple 3750 switches that I am trying to run VTP Version 3 on.one as primary and the other as "server" which implies secondary from my research. [code]Additionally, running a show VTP devices yields a "No VTP3 devices found" on both devices. Despite ensuring that the domainname and password match.I have a patch cable from Gi1/0/1 on switch one runnning to Gi1/0/1 which from what I read is acceptable on GigE.

A client of ours has installed an SG300-24P switch and would like to setup a LAG between the SG300 and the 3560 switch we manage for them. They would like the LAG to also pass the voice and two data VLANs currently in use; 5, 10, and 100 respectively. I configured the two ports as an Etherchannel with trunking on the logical port, but no luck. I reconfigured as follows:
interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
end
[code]....
I see no output when I do show lacp nei. At this point the client is looking to use for the configurations to use as he does not know how to setup the SG300 and it is a switch I have never dealt with. I have found some configurations that I believe would allow a single VLAN across, but nothing I believe will allow the LAG to pass all the VLAN's.

I have client who has two distant offices with 3750 L3 as core (do all vlan routing for local office) and multiple L2 access switches with multiple VLAN’s connected to it. First 3750 is hub also connected to internet, second 3750 is spoke and acting as a router on stick. We have eigrp configured on both side ISP provided client 100Mbps link as a trunk with two vlan; vlan10 for voice and vlan20 for data. We assigned two small subnets to these vlans 10.15.17.0/29 and 10.15.17.9/29. Hub addresses are 10.15.17.1 and 10.15.17.9 respectively. How to force voice over VLAN10 and data via vlan20, but still do some load balancing? How to setup default route on second (router on stick) switch?

I have a Cisco 2970 port 24 configured as a trunk port to handle all 11 vlans. This switch is also plugged into a couple other Cisco switches all is good on that side.
Here comes the ODD ball of the bunch. Since our wondeful execs wont let us buy anymore Cisco switches till our numbers get better they gave me this pos Netgear GSM7224. I know this isnt a Cisco product but someone out these has been thru this before.

if i have this config:
switch port mode trunk
trunk aloved vlan 50
will travel over this trunk untagged packets? For eg the V LAN 1 is by default native V LAN without tag. If i have created a bog ring with catalyst 3560x switches with no spanning tree on V LAN 1 can be the case of this config a loop ???
I am using upper config on interfaces that are connected the switches together in ring.
Other interfaces on switch have this config:
int range 0/1-4
switchport mode acc
switchport acc vlan1
int range 0/5-24
switchport mode acc
switchport acc vlan50
I am using vlan1 just for local switching without connection to internet! I am asking just because i have this king of messages in logs:
%CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on GigabitEthernet1/0/27 (1), with SW3560x_BR8874 GigabitEthernet1/0/19 (50).
GI 1/0/27 and GI 1/0/19 have this config:
switchport mode trunk
trunk aloved vlan 50

I have a test switch (Cisco 3550) that I want to set up with 6 Vlans and 2 trunk ports. I want to be able to access a virtual server conected to the trunk ports from the switch ports. Ports Fa0/1 to 8 are in a vlan port fa0/9 to 16 another vlan etc. Ports Fa0/47 and 48 are the trunk ports. This is a lab environment so the the switch is the only device being used.

I'm trying to configure a 2940 switch to trunk. I just can't get it to work.On the interface I have added: switchport mode trunk The default is encap for this switch is dot1q, so there is no need, or ability to add/change the encap mode. Also all vlans are being allowed by default. I still can't get any port to trunk. Need to get G0/1 to trunk, have also tried to trunk f0/6 to the switch in my office. Also can't find the command to change the management VLAN. I do not use vlan 1 for management. Can I change the Mang VLAN on this switch?

I have a 2960 switch connected to another. The I need to verify that vlan0010 on one switch is forwarding tagged traffic between the other switch it is hooked up to through the Gi0/1 port. How do I verify this? I have a server that's multihomed (Broadcom) on the other side an it is supposed to be on this vlan with one of it's network interfaces. We had a pwer outage and now it cannot communicate on this vlan. However, everything else on the vlan can reach all the other nodes accept this server in the front of my building. All the devices in the same room are linked to the same switch which has one port (fa0/17) on vlan0010 and can ping eachother just fine. The server is hooked to port 24 on my server room switch and Gigabit port one goes to a fiber converter all the way to the back. It then gets converted from fiber to cat5e again and links into the switch (2960) in the backroom.

Need to limit the amount of bandwidth a specific VLAN can use on a 802.1q trunk port. Situation is that we have a pair of Catalyst 4506 switches which have 802.1q trunk ports into a Checkpoint Firewall, this in turn is connected to a managed WAN router (to which I can't apply a QoS policy).If the 4506 was routing the traffic it would be easy to setup a class-map to match the IP traffic and then QoS the traffic, but the VLAN in question is trunked directly into the firewall (no L3/IP presence on the 4506 next hop for all clients on this VLAN is the firewall).What I need to do is restrict any traffic from this specific VLAN to 10Mbps on the uplink to the Checkpoint Firewall so it cannot impact the onward WAN.

I understand that jumbo frames need to be enabled end-to-end. I have two ESX hosts connected at each site. I want to enable jumbo frames for those ports, but what if not all host on the ESX are using jumbo frames, will I have drops and connection failures? So if i have two sites, each with a 6509 connected via a trunk and need to enable jumbo frames for a vlan between the sites how do I accomplish this?If I enable jumbo frames on the trunk link how does that impact other traffic between the sites?
