Cisco Switching/Routing :: To Manage LAN Users And Database Servers Traffic On Single 2960

Sep 6, 2012

For my Lan, I have created two Vlan; Vlan 10 = for Users   and    Vlan 20 = For Database Servers,There are 15 Lan computer/laptop and 5 SQL database server (Dell Server) connected through same 24 port cisco 2960 switch. Means, 15 + 5 port occupied.
 
I have applied access list on cisco switch to restrict communication between vlan 10 and vlan 20.But My main purpose to create two Vlan is not for any kind of communication or restriction. My main Purpose is that Users traffic do not distrub or choke or affect the Database servers. then what will i need to do for that is VLAN Concept is sufficient for my concern  OR  I will need to buy seperate Cisco Switch to connect 5 database servers   OR  Else ?

Cisco Switching/Routing :: Using Web Console To Manage 2960 Switch

Nov 13, 2011

I have a client whom has asked me to enable web management on some of his 2960 switches. I did not think this was going to be an issue, and so I told the customer I would set this up for him.
 
Much to my dismay, I have been able to get http and https enabled, and then authenticating locally for the HTTP access.  I then come to the screen once authenticated which is shown below:
 
The issue is that when I select "Web Console", it gives me a "Web Page Cannot be found".

Cisco Switching/Routing :: Catalyst 2960 After IP Change Via Web-Surface No Users Work Anymore

Sep 16, 2012

A customer contacted us that he can't connect his devices via web since he changed the IP address. Ok, big laugh "type the correct IP" but no. Even if you use the correct IP, no user can't connect anymore to the device. Also via CLI!The only thing that worked was the password recovery procedure. After that everything worked fine.The customer and me tried it again with another 2960, maybe there went something wrong when he did it last time and it was an accident. Nice thought but no: another device same error, no login possible.

Cisco Switching/Routing :: 2960 - VOIP Traffic Prioritization

Dec 28, 2011

I have a new VOIP implementation using 2960 switches. I want to prioritize voice traffic. After creating VLAN 2 I did the following:

Per Cisco, I did the following on my up-link ports:

switch port trunk allowed vlan 1,2
switch port mode trunk
switch port nonegotiate
priority-queue out
mls qos trust cos
switchport trunk allowed vlan 1,2
switchport mode trunk
switchport nonegotiate
priority-queue out
mls qos trust cos
spanning-tree port fast trunk
spanning-tree bpduguard enable
 
On my ports where a VOIP phone was plugged in, I did the following:
 
switch port trunk allowed v lan 1,2switchport mode trunk switch port no negotiate priority-queue outmls qos trust cos spanning-tree port fast trunk spanning-tree bpduguard enable
  
How can I verify that my voice traffic is being prioritized?

Cisco Switching/Routing :: 2960 / Traffic In Same VLAN Goes Up Trunk?

Feb 11, 2013

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

Cisco Switching/Routing :: 2960 - Test Multicast Traffic

Dec 6, 2012

Attached setup i am planning for testing multicast output from different vendors using  VLC and STB.  This Setup made to test the picture quality between the vendors at the same time on the multi viewer screen. 

1) Only a 2960 Gig port switch with only one L2 v lan with IGMP snooping enabled. 
In this scenario where Source and receivers are in the same L2 v lan ( no L3 interface is involved) hope i would able to test all the multicast sources with out any additional configuration on the Cisco switch.

Cisco Switching/Routing :: L3 - Traffic Between Two Servers Leave Switch And Go Up To Optimizer

May 15, 2013

I have a setup where two servers are on the same network are plugged into a L3 switch.  Off that switch there is a WAN Optimizer device which is inline going to the MPLS cloud.  Also off that switch is an ASA firewall which leads to the Internet for the location.  When the two servers communicate with each other i would think the traffic would only go through the L3 switch between the two servers.  I am seeing traffic between these two servers hitting the WAN optimizer for some reason.  I would think being that these two servers are on the same network the traffic between them would stay at Layer 2.  routing is enabled on the switch because of other vlans on the network. What would cause the traffic between the two servers to leave the switch and go up to the optimizer?  Below is a diagram that shows the basic setup.

Cisco Switching/Routing :: Setup VLan To Allow Video Traffic Between 2960 And 3750?

Nov 13, 2011

I am trying to setup a network using Cisco 2960 switches with vlans configured.  One vlan will handle video coming from four cameras that are connected to another 2960.
 
We have four cameras feeeding one port each on a 2960, that 2960 in turn feeds one port on the main 2960 which is the video vlan for that site.  From the site it goes back to a Cisco 3750 to be sent over to a Sonicwall firewall. If we connect to the 2960 that the camera are connected to we can see the video, but not on the main site 2960.

Application And Database Servers

Oct 13, 2011

I have question about the basics of a high performance application and database server connection to each other. I have two servers, one application and one database server. Both of them are Windows 2008 R2 servers. I would like to connect them. What is the best configuration for quicker communication between them. Is it better to connect them through a network switch? Or directly connect them? Do I need to dedicate one of the ethernet ports on each server to separate their traffic to each other, from the internet connection traffic?

Cisco AAA/Identity/Nac :: Using Active Directory Users To Manage ASA 5510?

Dec 28, 2012

I know that our VPN users currently use Active Directory to authenticate their VPN sessions, so now I'm wondering if there is an easy way to configure my company's Cisco ASA 5510 to use either a Windows Server 2008 R2 Active Directory group (preferred method) or specific Active Directory users (less preferred) and authenticate them for management access (privilege level 15) using their Active Directory credentials. I do not want this to change the IP range used for ASDM/HTTPS/Telnet/SSH access (currently all local networks, no VPN), as those are settings that my company does not want changed.

Cisco Wireless :: WCS 5508 Accessing Users From User Site Database

Jan 18, 2013

I work at a campus and use the WCS to control access to my network for staff and only internet access for students.  The Staff are assigned Username/password thru active directory and the student uses another SSID with only WPA --a password for all.  I was tasked with adding more securing for students -- by adding a user/password.  I do not want them connecting to my Active Directory for two reason--security risk and I have too many to input (over 1000).  So, I wanted to use our internal database to validate users.  I create a webpage with "WebAuth" that opens my logon page from my site and validates the login fields against the database.  It works and this allows the user to navigate thru my website but not outside the site. If they try an outside url it redirect them to my logon script.  I now understand why, so I'm looking for code I can add to my logon page that would allow me to redirect me to the controller's (once users are authenticated by my database) to call the WCS controller so I can enter a preset username/password so the policy management file would allow them access.  I presently use "External" and don't know if "Custom" would work. Finding a way in using a database instead of adding one person at a time?

Cisco :: 2950 / 2960 / 3560 / 3750 / 2125 / 1262 - Centrally Manage All Switches

Aug 27, 2012

I have more than 20 Cisco switches in my office which is basically a soap manufacturing factory. The switches include Cisco 2950, 2960, 3560, 3750 etc. We have routers also which include 2821, 2951 etc. We also have Cisco WLC 2125 and LAP 1262 series. Sometimes all these devices management comes very tough to us.
 
We need to log on to different devices for troubleshooting/network management which sometimes becomes very tough to us. So I wonder if there any Cisco applications or tools by which we can centrally manage all these devices.

Cisco Switching/Routing :: 3750 / Manage Multicasting On Another Router?

Feb 28, 2012

Within our small lan we have a core 3750, that handles our intervlan routing and is the core of the network. I recently looked into multicasting and set up a lab test with a 3550 with an EMI image and got the config to multicast to all vlans from one vlan, ready to go, at which point I found that our 3750 is IPBASE and doesn’t support multicasting. Currently upgrading the switch or image is not an option due to funding. My question is would it be possible and advisable to install our lab 3550 as a leg off the core, and in some way route multicasting traffic through that?I just cant get my head around the concept of having a core switch essentially routing all vlans, and then having another switch route the same vlan traffic again for multicasting to all the vlans again.

Cisco Switching/Routing :: 4506 - Cannot Manage One Switch Via Network

Nov 30, 2011

I have three 4506 switches with vlan 4 set as the management vlan. Switch 1 is connected to switch 2 and switch 3.
 
I can access switch 1 and 2 using telnet from the management vlan and both switches reply to pings. But from switch 1 or 2 I cannot ping or telnet switch 3. If I plug into switch 3 and I can ping and telnet switch 3 but not switches 1 or 2.
 
It is as if the management vlan 4 is not being passed to/from switch 1 and 3. The configs for the uplinks from switch 1 to 2 and 3 are the same. And the configs for switches 2 and 3 look the same apart from the port settings.
 
I have over 40 vlans running all that work fine between all the switches.

Cisco Switching/Routing :: 2950 VLAN Database VTP Management

Jul 4, 2012

spam up the boards with the same basic CCNA level stuff, but I have a couple of questions about ios differences, limitations, and references. I have the following three switches. One appears to be considerably dated in regard to software version. My confusion/ignorance stems from managing VTP settings.
 
2924XL     12.0 5 WC8
2950          12.1 22 EA6
2950          12.1 22 EA6
 
When I set either 2950 switch as the VTP server, and the other as a client, the client inherits the server settings as expected. However the 2924 requires that I go into the vlan database from priv exec and manually set vtp client. That's pretty similar to setting any switch to client mode. The problem I am observing is that after setting the 2924 to client, it still doesn't inherit vtp version settings or pruning settings. I still have to manually configure those. Additionally, if I copy run start the 2924 after making these manual settings, and then reload the switch, all the settings are lost and it defaults back to server mode with all features disabled. From my searches, it looks like vlan information is stored in vlan.dat, but all the documentation I've found is on 12.1 ios which doesn't appear to use vlan database for vtp setup, meaning it might still be an issue, but not one I'm focused on at the moment.
 
Is the vlan database dumped at reload? I've read vlan.dat is stored in nvram and should be saved after a copy run start, but that is not the case for me.I have since set the 2924 as the server, manually configured the server from vlan database, executed copy run start, and reloaded the switch. Oddly, my manual settings saved from the reload, meaning I only lose settings when the switch is in client mode.Am I missing additional necessary client commands to save the config, or is this just a limitation of either the 2924XL or the 12.0 ios?On a related but completed out of scope topic, without a cisco service contract, how am I supposed to make heads or tails of all the different versions of ios, along with the letter-based features and what-not? I can't even find my 2924 in the list of platforms when searching for ios upgrades.

Cisco Switching/Routing :: 3750 Manage And Configure An External Switch And Router

Apr 3, 2013

1. How I can manage those devices, the Switch and the router? What is the BEST SOLUTION to manage this devices?
 
2. I want to monitor the traffic on this environment, how I can do it? How I can monitor the traffic from customer A, Customer B, and my own LAN traffic, in terms of bandwidth that has passed throught my devices? Is it possible to monitor on MY LAN, or I have to monitor from the EXTERNAL switch?
 
3. How I can limit the bandwidth? I was trying to configure it using access list, with policy-map, etc....and limit this on each interface. [code]

The interface does not support the specified policy configuration and/or parameter values.Assigning a policy map to the output side of an interface not supported.With I few reading, I could see that the SWITCH 3750 doesnt support this configs.My INTERNET LINK is 30 Mbps, the ports on the Switch (WS-C3750X-48P-L) are Gigabit Ethernet.How I can limit the bandwidth here? For example, How I can limit a interface to 3Mbps..I was thinking about this:

- Limit the interface to 10Mbps: speed 10

- and limit the interface with 30% of this speed:  srr-queue bandwidth limit 30
 
Does this work for both UPLOAD and DOWNLOAD?When the packets passes that 3Mbps limitation, will they be droped?

Cisco Switching/Routing :: WS-C3560G-24PS Configuring Ip Dhcp Snooping Database With Scp

Feb 10, 2011

Just spoke to the TAC and didn't get the information needed.  When configuring ip dhcp snooping database I am adding this to my configuration:ip dhcp snooping database scp://dhcpsec@192.168.1.50/home/dhcpsec/switch1.dhcp.database.txt..I assumed that to do this I would either specify the password on the command line, similar to the way its done when using ftp/http, or that I would need to create a public/private key.I have enabled scp and can manually copy a file from the switch to the linux server. So I believe I have all the aaa commands correct. Cisco WS-C3560G-24PS System image file is "flash:/c3560-ipservicesk9-mz.122-55.SE.bin".
