Cisco :: Catalyst 2960 Two Macs On One Port Need Two Vlans?

Aug 7, 2011

I have a device that does ip audio on one mac address and managagement is on another mac address. Both of these mac addresses come from one NIC on the device. We need to split these two traffic paths into two different vlans.How can I program this switch to sperate the different traffic into two vlan's based on mac address on one interface?

Cisco Switching/Routing :: Integrating Catalyst 2960 With Juniper Core And VLans

Mar 7, 2012

I've just started a new job after a couple of years not touching cisco gear and been pitched in... My new employer has a network that's Juniper based. We've inherited a load of Cisco switches as part of the deal for hosting matches during the Rugby world cup (plus a load of Aruba wireless gear that promises to be my very own special millstone, but that's bye the bye.)
 
My task is to hang these catalyst 2960's onto our existing infrastructure via fibre connections.
 
On the Juniper switch, there are four vlans being pushed to the port the cisco's hooked into: Code...

Cisco WAN :: Cat 3560-E / 2960-G - Configuring Two VLANs On Same Switch Port

Mar 29, 2012

As per my attached diagram, I have three switches (Cat 3560-E and couple of Cat 2960-G)

Each PC is on different vlan
PC -1 on vlan 100
PC-2 on vlan 200

I need to connect PC-1 and PC-2 to the server. Server has no fixed vlan and can be changed.

Restrictions:

1) can’t change PCs vlan assignment.
2) can’t add 2nd NIC in the server.
  
I’ve tried private vlan but it requires separate physical ports for host and/or community vlan and somehow it did not work. I could be wrong Trunking using dot1q enabled on port 2 on all switches and connection works fine (server to PC-1 or server to PC-2) by enabling switchport access vlan 100 or switchport access vlan 200. However I need port 5 on switch-1 to respond to vlan 100 and 200.

Cisco Switching/Routing :: 2960 - Multiple VLANS On 1 Switchport

Apr 30, 2012

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.

Cisco WAN :: 2960 / Block Traffic Under Two VLANs - Unidirectional Or Bidirectional

Aug 22, 2012

I have a Ciso L3 switch with 4 VLANs and all host computer connected to rest of 8 cisco 2960 switch's:
 
VLAN 1  : 192.168.1.0/24
VLAN 10: 192.168.10.0/24
VLAN 20: 192.168.20.0/24
VLAN 50: 192.168.30.0/24
  
There are list of my some Questions about Extended ACL serialwise :
 
1. For Restrict traffic from VLAN 10 to VLAN 20, I am using  only one ACL is : Access-list 100 deny ip 192.168.10.0 0.0.0.255 192.168.20.0 0.0.0.255.\  What will happen in this scenerio if we talk about traffic from VLAN 20 to VLAN 10. Will it communicate or not ???
 
2.   How to Block the traffic from VLAN 10  to  VLAN 20 but allow the traffic from VLAN 20  to  VLAN 10 ?

Cisco Switching/Routing :: Multiple Vlans On Catalyst 2950?

Sep 13, 2012

I have a above said switch at my remote office (600KM) which is connected with L2 Point to Point leased line. Both the ends I have Cisco 3950 catalyst switches with Vlans configured at both the ends. Now, for obvious reasons I should remove the other end 3950 switch and replace with Cisco 2950 switch. The other end 3950 is having 4 Vlans configured on 4 ports. Now my requirement is, I should configure 3 Vlans (one for P2P, one for 10 Desktops and one for to bring traffic from other network).

Cisco Switching/Routing :: Catalyst 2970 Switch For 2 Vlans

Oct 14, 2012

I am using a catalyst 2970 switch for 2 vlans. Corporate data and a separate VLAN for backups. What I want to do is create an LACP etherchannel to the switch and also trunk these ports so the server is part of both VLANS.Due to fact that some of these servers are on totally separated networks, they really shouldn't be able to talk to the backup server. Creating the VLAN for backups works to achieve this. I plan to create inbound ACLs on each port to allow only the ports and IPs for the backup network and allow everything we need for corporate data.I read somewhere that you can't have ACLs on an etherchannel and I just want to get it all straightened out. I notice I can't add an access group to the port-channel itself but I can on the port- channel member ports. Is this all I need to do or does this not work?

Cisco Switching/Routing :: Private Vlans Across 2960 / 2950 Switches?

Nov 12, 2012

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?

Cisco Switching/Routing :: 2960 - Connecting Two Vlans To 1 ISP Router Interface

Dec 19, 2012

I have two Catalyst 2960 Series (48 port) switches with the newest Cisco IOS installed. There is also a Cisco 2600 Series Router which I can't manage because it's ISP managed.
 
Now the problem is as follows. I'd like to create two VLANs, one in the IP range 192.168.0.xxx and the other in the 192.168.1.xxx. Now the router has a gateway IP address 192.168.1.1 .
 
Would it be possible to somehow connect these two VLANs with the router so that these 2 VLANs can't see each other but they can ofcourse both contact the router and exit on the internet?

Cisco Switching/Routing :: Maximum VLANs In Transparent Mode 2960

Nov 22, 2011

On a low-end switch like a 2960 the maximum VLANs is 255, as shown in the output of VTP status:
 
Maximum VLANs supported locally : 255
Number of existing VLANs : 245
 
When the VTP mode is changed to transparent, VLANs from the extended range can be added without increasing the number of existing VLANs - e.g. if I create VLANs 3000 - 4000 the number of existing VLANs is still listed as 245.
 
If MST is used to cut down on the number of spanning-tree instances - and assuming propagation of VLAN configuration via VTP is not required - is there any downside to using transparent-mode VTP to increase the number of available VLANs? It does feel like I'm cheating the maximum listed in the datasheet.

Cisco :: LMS 4.0 IOS Upgrade For Catalyst 2960?

Feb 16, 2011

I tried to update Cisco Catalyst 2960 Switches through LMS 4.0
 
But LMS won't update the 2960 because there is not enough Flash Space on the device. The 2960 shoud have 32MB but a dir flash shows this
 
27998208 bytes total (15343104 bytes free)
 
A manual update on the switch is working perfect. Is this a bug or if there is a workaround to make LMS 4.0 working?

Cisco WAN :: Configuring NAT On Catalyst 2960

Jan 4, 2011

I've just made a purchase for a Cisco 2960 8 port switch ( Exact model: WS-C2960PD-8TT-L ), I reckon this is what I need to set up my network, so far I've gone through the Express Set-up and configured it through there with no problems. I've set up the hardware in the following manner:
 
 -Internet Modem
>Port 8 on Switch
->Port 1 on Switch goes to 1252 Cisco AP
->Port 2 on Switch goes to Linksys VOIP home Router
 
I let it start up and can connect to the internet through the AP, and through the router. (I'm posting through the AP-Switch set-up right now.) However, once I connect to the AP with a second client. It refuses to let the second client connect/not give an internet connection, as it would a direct connection to the modem.I'm going to assume this is due to NAT not being configured through the command line on the switch yet.

Cisco Firewall :: Configure ASA To Send All Traffic From (3) VLans To Interfaces That Connects To 2960?

Apr 18, 2013

I have a an ASA 5520 connected to a Layer 3 (3750) switch (Inside) and a connection to a 2960 switch (Outside) to get to the internet. . I have created vlan interfaces on the 3750 switch and enabled ip routing on the switch to enable the vlans to communicate with each other.
 
Vlan Interfaces on the switch:
Vlan 100 172.17.1
Vlan 200 172.18.1
Vlan 300 192.168.3.1 
 
I want the devices connected to the 3 vlans to be able to pass through the firewall and get out to the internet.I have connected the ASA to the 3750 by routed interfaces (10.10.10.1) --------- (10.10.10.2) and they are able to ping each other.I have also put a default route on the 3750 sending all traffic from the switch to the ASA inside interface (10.10.10.1)The issue that i am having is that the ASA also connects to a 2960 which has a connection to the Internet, and they are handing off an ethernet connection from the 2960 that sits in VLAN 55 (Vlan 55 is the Internet accessible vlan).How do I configure my ASA to send all traffic from my (3) vlans to the interfaces that connects to the 2960 switch?

Cisco :: Bandwidth Monitoring On A Catalyst 2960

Oct 23, 2007

I'm working with two Catalyst 2960 switches and I would like to know if there is a way to monitor bandwidth on individual ports. Ideally I would like to have one graph showing a bandwidth usage reading on each port. I tried using the Network Assistant to accomplish this, but I was only able to view one port at a time. I also tried using  a traffic graphing program from Paessler, but a MIB file is needed to allow the program to connect to the switch. When I ran a search  on the network management page the 2960 was not on the list for MIB supported products. Is this type of graph possible to do?

Cisco WAN :: Radius Authentication On Catalyst 2960?

Apparently there are no requests made to the radius-server, since I dont see any requests coming in. Port 0/7 is voice port with laptop behind , /port 0/8 access-port with laptop directly connected.

Cisco :: Network Assistant MAC Search In Catalyst 2960

Since I updated a Catalyst 2960 switch to IOS version 12.2(55)SE1 I can't do searchs by MAC address, when I do "Monitor->Search" the following error appears:"The software version of the selected switch does not support some of the CLI commands in read-only mode for this window. You must have read-write access to this switch to display complete information in this window" If packets are captured you can see that the issued command by the CNA host is "GET /exec/show/mac-address-table/", the answer from the switch is:"show mac-address-table ^% Invalid input detected at '^' marker.
 
If I do "Configure->Switching->MAC Address" instead I get the mac address-table correctly. In this case the issued command is "GET /exec/show/mac/address-table/dynamic" and no error is displayed, the answer from the switch is the list of mac-address table.
