Cisco Switching/Routing :: 2960 Support Multiple Vlan Per Port?
May 21, 2012
We're going to be switching some of our gear from Foundry to Cisco, and were looking at the WS-C2960S-48TS-L. We currently have 3 different VLAN's, and I wanted to have 1 uplink back to our firewall (ASA 5550) and then let the firewall do the routing between the subnets. I realize that 1 link will carry the traffic twice then, but is that possibly with those switches to have all three vlans assigned to one port and then just let the firewall do the routing between the vlans or would I need to have 3 uplink ports back to the 5550?

Using Cisco 2960 series switches (Have 8 . 2 stacks of 4) to replace 6 old switches. 4 old switches had IP ranges of 192.168.6.*** and all new switches have 10.1.*.* addresses. Core switch has 10.1. as well as 192.168 ip addresses but i need to configure one vlan (5?) to route to 192.168 address. PC's on 10. address taking a long time to access 192 range.

I have a Cisco 2960 48-port switch. I enter "sh vlan" and it lists all the VLAN's. One of the VLAN's listed is "10" with the name "EPIC". What is the quickest way to find out what ports, if any, are assigned to this VLAN?

I'm new to networking and was looking for some assistance. First off im using packet tracer to diagram my senario as I will be receiving my equipment next week to deploy.
Hardware to be used:
1. 2 catalyst 3560 switches
2. all connect to a sonic wall router
I have two companies that work in the same office space. I need to keep these companies seperate on their own vlan. They will however need to share the phone system.(Packet tracer file uploaded to give those who have the time to see what I put together.) [code]

I have a a hardware server running a VM hosting virtual servers which are all on different VLANs. My challenge now is to configure the switchport that the server is connected to, to see all the VLANs needed by this VM. The VM has an IP that is used for managing the server VMs which is on a different VLAN also.
My switch is a 2960 switch and it is presently trunked from the core switch.

I have a customer with Cisco 7940 and 7960 IP phones that they do not plan to replace. They do want a new LAN and are looking at the Catalyst WS-C2960S-48FPD-L and WS-C2960S-24PD-L as access layer devices.
these switches support the Cisco pre-standard PoE required by the 7940 and 7960 IP phones.

In our network environment, we have a 2960 switch sitting behind our router. Off of this we have a lot of external connections, like our external DNS, firewall, and VPN concentrators. I've configured a VLAN other than the default, moved everything into it and then shut VLAN 1. In this hardening guide it says that your native VLAN should be something other than the user VLAN, but if I am not using any trunk links, wouldn't I not really have a native VLAN? I attempted to make the link to our firewall a trunk link and then set the native VLAN to something else.

I am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?
what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature

Coincidentally when i tried to configure router 877 as an adsl router i found that a vlan configuration is included. my question is what is the benefit of using vlans in router ??? i studied that we use it in switches for the purpose of network enhancment from broadcasts and netwrok segmentation. why we use vlans in routers ?

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
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate

I have two questions for a Cisco 2960 (WS-C2960-24TC-L)
1. I am working to setup a few Cisco 2960 switches for HP iLO access to our servers. We are going to segregate the iLO network (VLAN 40) from the data network (VLAN 10) by using a different VLAN. All of the HP servers will be configured with static addresses. My question is, how do I set all the ports to VLAN 40 so that untagged devices will automatically go onto VLAN 40? I don't want to have to configure the VLAN on each iLO port on the server. I tried to set the port to: "switchport trunk native vlan 40", but that didn't work.
2. Also, how do you access the web GUI for these switches? I get a login box, but putting in the enable password doesn't work. I have the following commands in the config: [code]

we have inserted into a network with VTP a Cisco Switch 2960-S, not knowing that had installed IOS LAN lite.Now I discovered that it can handle up to 64 vlan. In the network there are currently configured 62 VLAN: what happens when we exceeded the max number (64) of VLAN for that switch?

I have a 2960-S running the lastest software for testing on my bench:
[code]

I have set up VLAN 2 on 192.168.2.0/24 with the switch as the DHCP server. The switch is connected to an RV082 router which is at 192.168.1.65/27. Once I figure out what I doing I'll eventually shift that to 192.168.1.0/24 or something similar. So I have my switch acting as the DHCP server for VLAN 2 but I can't figure out how to get it to access the internet.
I found this example to set up the DHCP server:
[code]
###################################
this works to get vlan 2 to serve ips
conf t
[Code].....
The RV082 doesn't support trunks AFIK and I'm pretty much a newb at this stuff. TIA. I guess I should get a real router and I most likely will but I'd like to get this working if possible before taking the next plunge.

I have a 10nos of cisco 2960 switches and 1no of cisco 3725 gigabit switch. all 2960 switches are parallaly connected to 3725 switch though fiber.
all the switches are having same vlan and public ips for management.
Now I want to upgrade IOS for all 2960 switches at a time, how to up grade IOS same time for all switches.

I have a problem with DHCP. I have two 2960 connected with a port channel on ports 47 and 48 as trunk with native vlan 10. I only have this one vlan. In port 1 of sw 1, I have a C800 as DHCP server.
I have an AP autonomous with single ssid on vlan 10. When I connect the AP to sw1, I receive dhcp with no problems.When I connect the AP to sw 2, I’m not getting IP by DHCP.I have DHCP snooping working on vlan 10 on both devices.
The ports where I connect the AP are access ports on vlan 10 config as trusted.The trunk ports are also configured as trusted.The port 1 of ws 1 that goes to the C800 is also configured as trusted.
figure out why I’m not getting IP by DHCP when I connect the AP to the SW 2.The only I notice is that when I connect the AP to sw 2, I get on SW 1 the message of packet drop by option 82, but even after configuring ip dhcp snooping information option allow-untrusted on both switches, the problem persists.

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.

Setup is like this: Poly com IP phones -> Cisco 2960 switches -> Cisco 2621XM router running 12.28(r). A Windows 2003 server running on HP Proliant DL380 G4 with the correct DHCP scope is configured for the IP phones, also sitting on a Cisco 2960 switch.
A typical port config on the 2960 is:
interface FastEthernet0/1
switchport mode access
switchport voice vlan 60
mls qos trust cos
auto qos voip trust
spanning-tree portfast
spanning-tree bpduguard enable
Relevant section of the config on the 2621XM router:
interface FastEthernet0/0
no ip address
no ip redirects
no ip proxy-arp
ip pim sparse-dense-mode
[Code] .......
This used to work on a Windows 2000 server which sat on different piece of hardware, but stopped immediately after the migration to Windows 2003 server was done. There was no change on the router or switches prior to or after the server migration. I see DHCP server log on the 2003 server giving DHCP NACK because the phones are apparently asking for IP's in the data VLAN.

I 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?

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]
