I am using an Old 3500XL and I simply created a
interface VLAN 100
Description ***********
ip address 10.0.1.100 255.255.255.248
no ip directed-broadcast
no ip route-cache
shutdown
no matter what I do i cannot get it to come up, the rest of the switch is default config, I know I am just forgetting something, But I don't know what?
I have a POE switch running 12.0(5). I have port 24 connected as a trunk connected to the main switch. I need to add an ip address on vlan 21 which is where the network vlan is. I created it but I can not seem to enable it. I have issued the no shut command several times, but doing "sh ip int brief" it keeps showing up as administively down.

I installed wireless controller with 4 APs and controllers sees all 4 APs. Controller is also DCHP server. When wireless client authenticates it's DCHP requests in not getting to DHCP server (controller). If i connect all equipment in non managed switch everything works.
View 10 Replies View Related I'm having some trouble getting my head round the following but I think it's routing related?
I have a Cisco 3750 switch with the following configured:
interface Vlan1
ip address 192.168.0.223 255.255.254.0
no ip route-cache
[Code].....
The 3750 is connected to a firewall which handles the routing. From the 3750 I can only ping remote networks from the vlan1 interface not from vlan6,8 or 10 i.e ping 10.34.37.101 (remote network) source 192.168.0.223 (vlan1) works but ping 10.34.37.101 source 10.74.10.1 (vlan10) does not? I can ping 10.34.37.101 from computers on the various vlans but not from the 3750 it self.
I looked at setting a default gateway for the various vlan interfaces
I've gotten this out of our storage unit here at work: This was not in use, I've restarted it, I can't get into the flash dir,I've tried to restart the switch via the documents I've gotten on the site.I have the lastest iOS version .bin for this switch, but I can't get this to load: here below is what happens when I try.

View 8 Replies View RelatedI have several Cata 3500XL switches connected to one 1 HP L3 switch which is connected Sonicwall router. Vlan1 has subnet of 10.10.0.0/24 and Microsoft DCHP server lays inside VLAN1.
Now i want to add VLAN11 (192.168.10.0/24) as second data VLAN but DHCP requests should go to microsoft DCHP server.
This is what i did:
Configured VLAN11 IP on each cisco switch
IP default gateway with IP from other subnet (i guess this is bad since maybe it should be IP of VLAN11 on HP L3 switch?)
Trunk ports are configured to pass everything on cisco switches
On VLAN11 i configured IPhelper IP to be MS DHCP server on each Cisco switch
I haven't tested this yet but i have problem in process.I can't ping VLAN11 IPs between switches (i configured VLAN1 and VLAN11 with IP). When client plugs computer to a port that belongs to VLAN11 will i be sure that client will get IP from the 192.168 range or there is possiblity that he gets IP from the management VLAN range?
I am trying to configure a 3500XL switch (and I know its old). I get to the int fa 0/1 line and thats where it all stops working.
switch#(config-if)#switch port mode access
switch#copy run start
or
switch#(config-if)#switch port mode access
switch#sh run int fa 0/1
It will show the configuration for port fa 0/1 as if I hadn't entered the "switch port mode access" command. Or any other command for that matter. Why the switch is not holding configuration and seemingly loses it as soon as you exit out of each interface?
Between our hosting and a customer we have an extended vlan, traveling on a fiber, between two cisco 3560 switches.The thing is, that we want to create one or more vlans inside that extended vlan, in some way if possible?
View 3 Replies View RelatedI have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50

SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
i need to solves this little problem on 2960S lan BASE but i dont know if it is possible.
Uplink port config for gi 1/0/28 is:
switchport mode trunk
switchport trunk alloved vlan 10,11
but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20.
At this time i have solved this issue very primitively
I have set up gi 1/0/2 as int mode acces, acces vlan 20 and i have connected gi 1/0/2 with gi 1/0/3 with eth cable. int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10
I have a 3750G switch in my production network that only has VLAN 1 on it. All ports are in a default state and VLAN 1 is disabled. The switch is passing traffic but shouldn't having the default VLAN shut down cause the ports not to pass traffic? If I start to create VLANs will that cause the switch to stop passing traffic?
View 4 Replies View RelatedI am trying to setup a L2tpv3 VLAN-to-VLAN tunnel.My setup has two Cisco 890 router with Cisco IOS Software version 15.0(1) M4. These routers are connected directly on FastEthernet port 8.
One linux machine is connected on FastEthernet port 0 on each router. The two linux machines are on same vlan. I am trying to establish a vlan-to-vlan tunnel between the routers and send traffic between the linux machines.
I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.
(config)#vlan 200
(config)# interface FastEthernet 0
#shutdown
#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?
We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP

And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.

I have a problem accessing my wireless router through VLAN sub-interface on my Cisco 1841 router. My hardware:
Cisco Catalyst 2960 switch (192.168.100.4 /24)
Cisco Catalyst 3550 switch (192.168.100.6 /24)
Cisco 1841 router (192.168.100.7 /24)
Asus RT N66U wireless router (192.168.100.2 /24)
Here's my network topology:
I have two VLANs - 10 and 20. 2 DHCP pools are configured on 2 1841's interfaces - 192.168.1.0 /25 and 192.168.1.128/26 with default router sitting on 192.168.1.1 and 192.168.1.129 respectively. No issues with obtaining IP address from any of those pools.Laptop connects to L3 3550 switch (switchport access vlan 10), which, in turn, connects to 1841 router through trunk (with VLANs 10 and 20 allowed).3550 is connected to 2960 through trunk with VLANs 10 and 20 allowed.Wireless router is connected to 2960.I can successfully ping my wireless router and outside world from 1841 from fa0/1 interface, but not from fa0/1.10 or fa0/1.20 sub-interfaces - all packets got dropped. My laptop can obtain IP from both pools (depending on port I connect it to), but can't ping my wireless router and anything beyond it.

View 1 Replies View RelatedI am trying to connect a 6509 switch to a 4503-E switch using single mode dark fiber over a distance of less than half a mile. Although a routine task, it does not work..We have a care 6509 switch where we concentrate all of our dark fiber connections for our remote sites. The 6509 switch already has 30 remote sites, most of them with 4503-E switches, connected in this way therefore it is a tested scenario. For the connections we use the GLC-LH-SM SFPs on both switches. Out of these 30 sites we had a similar problem with two of them, which we solved with the use of CWDM SFPs. With the CWDMs the fiber came up right away. However, I cannot keep using this solution because it is way too expensive! I had the losses of the fiber measured end-to-end and they are negligible (>0.5 dB).
In this latest case, like I said, we could not bring the connection up between the core 6509 switch and the 4503-E switch using the GLC-LH-SM SFPs. I then replaced the 4503-E switch with a 3560 and the link came up! Then I tried using a CWDM-SFP in the 4503-E, while keeping the GLC-LH-SM SFP in the 6509 and the link came alive again! Of course we already tried replacing the fiber patch cords with no luck. [code] I find it very weird for the link to work with the 3560 or with a CWDM in the 4503 but NOT with the SFP in the 4503!
I have a Nexus 5548UP that would be managed by two organizations. Is it possible to set IP addresses for mgmt0 and an SVI (or an L3 interface) without using the L3 daughter card? I don't want to route between VLANs, just to separate management traffic.

On two switches so far, we are seeing that clients can not connect, and the switch isnt detecting a link.

I have two switches (sanitized configs attached) and I am trying to bond int gi0/1 and gi0/2 between the two. Then I need int gi0/3 back to the main LAN switches. These are new Vlans created 982 and 983 for these switches. Question #1: do the configurations look correct? I haven't placed any laptops on the interfaces to test interconnectivity yet but I am wondering if it will work with no default routes.
The admin team needs these switches at location A for setup then they will be moved to Location B. The only thing that sucks for me is that the network admin before me created gateway interfaces for all the local Vlans on a main router as sub interfaces. For example, for these two subnets, I need to create subinterfaces below (at location A), which is why a gave the Vlan on the switches, ip addresses.
interface GigabitEthernet0/0.982
encapsulation dot1Q 982
ip address 10.98.2.1 255.255.255.0
ip flow ingress
no cdp enable
service-policy input mark-mplsqos-in
interface GigabitEthernet0/0.983
encapsulation dot1Q 983
ip address 10.98.3.1 255.255.255.0
ip flow ingress
no cdp enable
service-policy input mark-mplsqos-in
When I move the subnet to location B, I will also move the gateway. These two switches will be used mainly for a VMWare and HyperVisor environment so Vlan 982 is for VMA network and Vlan 983 is for management. The admin tells me the software needs to tag the packets, I am not sure if I care as the switches should handle that also.
