We got a layer3 switched network, with one vlan for every switch, routed by a cat4006. [code] So can we put some ports on different switches in, let`s say vlan 50, with different ips? For example, Port 0/3 on Switch 1 and 0/8 on Switch 2, but keeping the ip of the "old" vlan? Or is it necessary to configure a specified vlan interface with ip-adress for every vlan if i want to route it?
View 4 RepliesI need to create several VLans on my switch.After reading the admin guide pdf, i still don't understand how to create any simple VLan.some tutorial or steps (with IE or Mozilla browser) how to create and use VLan, and to connect one VLan to another.For example,i need to create 3 VLans.
First Vlan consist of 5 ports (Vlan Name = Red)
Second Vlan consist of 15 ports (Vlan Name = Green)
Last Vlan consist of the rest of the ports (VLan Name = White)
I have an older 4006 with a Supervisor II+. We now need OSPF support, which the Sup II+ does not provide. I have access to a Supervisor III (WS-X4014), which will provide OSPF support. Question is, are there any gotchas to shutting down the switch, replacing Supervisor Engines and then powering up? What about the flash card? On my current system, it appears that I am only using bootflash: , which is where the IOS resides (see below). Since my startup config is in nvram and my IOS is in bootflash, what's the purpose of the flash card in slot0: ? and where does NVRAM and bootflash actually live on a 4006 ( on the Supervisor Engine?)
sh bootvar
BOOT variable = bootflash:cat4500-ipbase-mz.122-31.SGA11.bin,1;,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist

we got a problem with our cat4006 coreswitch. The led on the supervisorengine is red, and several errors are appearing in the message log. [code]

View 2 Replies View RelatedI am trying to set up a network that has 1 internet connection, requires a local LAN for the business, and another LAN for public wireless access. Here is what I have and details on what we want to do.
1- Cisco ISA570 Router no WIFI
1- SG500-52P switch
6 - WAP321 Access Points
We have the main LAN set up and all is working well, internet access, 6 WAP's connecting and all is working like a charm. Internal IP range is 192. 168. 0.0/24.We have all 6 WAPs on the internal network, with 2 SSID's on each WAP and each SSID is assigned to a VLAN. One SSID is internal for staff, the other is for guest access for members. The internal staff wireless access is working fine.
We want the guests to be able to access the internet, but not the internal network, but we need to access them for administration from the internal network.
We created a second VLAN on the switch and added the 6 WAP ports to it as tagged for VLAN2. These 6 ports are also on VLAN1 (default). We have a second VLAN on the router, have it handing out DHCP addresses for the 192.168.25.0/24 range with DNS servers.
Where we are having trouble is with getting the guests wireless access to work. Guests can see the wireless, log onto the access point but that's it. They don't appear to get a 192.168.25.0/24 IP, or any IP actually, and thus cannot do anything.
I need to convert configuration from CatOS on 4006 to IOS on 4510. I am unable to find the conversion tool.

View 1 Replies View RelatedI have a really weired thing happening on 6509 device with one of my customers.The device has a SUP 2 (MSFC2) with version 12.2.18SXF17B.
any VLAN interface once administratively down or simply down shows on "show interface status" output as VLAN.While it supposed to show "Routed". However once the port is up it is shows "routed" like it should.
I understand the vlans on the catalyst side of the house on 2900 to 6500 Catalyst switches.
This 7010 running nx-os 5.1(3) I did not setup, but have to manage it. Hasn't really been a proble till now.
My nexus 7010 has a Layer 2 only vlan 11. It is "Active" but the interface is "shutdown". Yet, it is passing traffic across the directly connected ports on the nexus 7010 and to other switches in my network. Vlan 11 is being set out via VTP to all my switches and things are running fine.
I need to create another L2 only Vlan. I can't seem to find any docs that indicate that a Layer2 vlan Interface on nx-os should be in "shutdown" mode as part of the setup. I do see in the docs where it has to be set "Active" as part of the process.
Is this the correct way to seutp a L2 only vlan on nex-os? Leave the interface in "shutdown" but make it "Active"?
Mystery Vlan 4 and 6
The mystery deepens. I have other L2 vlans ,Vlan4&6 that are NOT defined as "Interface Vlan4" in the nexus config, yet it is applied to GigE ports on the nexus and these Vlans 4/6is also being sent out VTP to all switches. Even weirder is that these vlans have names associated with the numbers. These are valid Vlans that were configured on the old 6509 before the Nexus was installed.
I have checked all switches, NONE are running in Server mode for VTP, all are in CLIENT. The nexus 7010 is the only device running in VTP Server mode.
i'm going mad on following problem. I'm trying to get 2 networks seeing each other while one of the network is a non VLAN network and the other one is a VLAN network.They should use the same interface so i added VLAN e0/0.122 to the interface e0/0.Send a ping from my asa to both gw-IP's made me happy at first. In second in figured out that i cannot reach any client in the other network. For testing purpose i created an permit acl to any/any for both networks, but the packets still get dropped by the default implicit rule. (deny any/anyMaybe i'm to stupid for this

View 6 Replies View RelatedI have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

To add a little complexity the main comms area is located in the basement of the building, this houses the 2 DSL routers and 2 Servers, one for each company. I am proposing putting the SG 300 10 port switch in here and then use the 3 uplinks I have been given to connect back to the SG 300 52 which is in a patch cabinent 2 floors up. I want to use 2 uplinks (in a LAG) for Company A and 1 uplink for Company B. FYI. DHCP is being served out by each respective router.

View 4 Replies View RelatedI have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?
View 2 Replies View RelatedI have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).

View 12 Replies View RelatedI have a DC topology based on 2 layers, access and aggregation, based on 2 pairs of N5548Ps, both without L3 Daugher Cards. My intent is to use the aggregation N5K pair as L3 inter VLAN layer, so I configured all the VLAN default GWs there. The 2 layers are interconnected via vPC, in a double-sided vPC topology for some N2Ks and some vSwitches. The point is that, despite connecitivity is working fairly ok, for some applications, like file transfer via either FTP or HTTP, between hosts in different VLANs, the performance is too poor. The file transfer starts ok, but after a while it becomes lower and lower. ICMP is working, but I can see some strange random behaviour, like having some packets taking more that 20 ms (sometimes 40 or more), whilst average is 2 ms.
I read through some articles saying that until you don´t have the L3 license (the one coming with L3 Daughter Cards) you can expect some weird behaviour on L3 level. Is that true?. What can I do apart of purchasing L3 Daughter Cards?. Can I enable L3 Basic license at the moment (I don´t need dynamic routing for now).
Here some excerpts of what I´m saying:

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]
We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]
