Cisco Switching/Routing :: InterVlan Routing With 3750 And 2960 Switches?
Nov 21, 2012I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

Mar 12, 2013We have 3 layer LAN architecture, layer 1 of 6500(IP routing), layer 2 of 4500(L2 switch only), layer 3 of 2960(L2 Switch)In a Single (2960 and 4500) Switch Port Avaya IP phone and PC are connected.Now, the requirement is that, Qos need to be configured for Voice traffic and Data traffic should be in default class of service.We plan to use COS value in Switch 4500 and 2960. We made a sample configuration as below
### For 4500 Switch
class-map match-all VOIP-Access-2MB
match cos 3 5
class-map match-all VOIP-Uplink-20MB
match cos 3 5
[code].....
check these configurations are correct as per standard and if there is any other method of configuration?What need to be configured in L3 Switch(6500)??In 2960, it doesn't support ingress QoS, what impact it will make when compare to 4500? do users experiance any difference?

Mar 22, 2012Company I work for just moved into a new location. We have two data closets which are patched as independent entities, with no Ethernet tie connection. These closets are roughly 100 feet apart.
There is a fiber connection that runs between both closets, that the previous tenant used to connect the switches. I have placed a Cisco 2960 switch in each location, and added one mini SFP gbic's to each switch. After attaching both sides, neither light up. I do a sh inter gig1/0/49 on each and shows 'down down' (not admin down).
What is the trick on getting these to communciate, do I need to configure these ports, and are they supposed to light up?
What I am trying to accomplish is to get the one closet that is completely cut off, communicating by logically stacking, or 'daisy chaining' via fiber.
I turned off the lights and popped the fiber out, and I do see a faint red light (I did not look straight into it), so I think the fiber is active.

May 25, 2013I need to connect 4 Floor Building with 4 Cisco 2960 - 48 ports switch each other and it needs to be through a fiber. So all PCs connected to each switch would reach the LAN/WAN from the other switch. (attached is the image here with)
I see that the 2960 has 2 SFP ports each port of each switch should connect each other or how?
My simple question is:
1. What cable / patch code I have to use = Single-mode or Multimode? ( distance for each switch will not more then 25 mts)
2. Do I have to use SFP or SFP+ module?
3. What kind of SFP/SFP+ module I have to use = Single-mode or Multimode?
4. What kind of connector should patch code have = LC / SC or ?
5. How to connect each switch with redundancy like ...each switch should be interconnected with each other or I have to choose Cisco 3750G which has more then 2 SFP ports (option#1 & opetion#2 = attached here with) =

Cisco Switching/Routing :: 2960 - Web Authentication On Switches For 802.1x Incompatible Clients
Apr 2, 2013I am trying to get to work Web-based authentication on Catalyst 2960 and 3560 for clients that don't support dot1x. I followed this guide. Here's the problem: Client (win7) joins the network, opens the web browser and tries to navigate to any http site. The switch forces him the "login" page in which he has to enter credentials. After the client enters credentials, the switch sends http 500 internal server error page and nothing happens. Doesn't matter if the credentials were correct or not. Also i checked radius logs for requests, the switch doesn't even ask radius.
The configuration:
sh ip admission configuration
Authentication Proxy Banner not configured
Consent Banner is not configured

View 7 Replies View RelatedCisco Switching/Routing :: Config Erasing Automatically On C500 And 2960 Switches?
Feb 8, 2012 I have a scenario where 15 c500 switches and 5 2960 8 port switch connected to 4507R core switch. There are 10 dhcp pools created on the 4507.
Eg: ip dhcp pool XXXX
network xxxx.xxxxxxx
default-router x.x.x.x
Now the default router is directed to vlans created on the switch i.e vlan 101, 102, 103 and so on. Now the remaining switches connected are configured to be in the same vlan. So the systems connected to the edge switches will get the DHCP ip automatically, Now my problem is after sometime (may be 2 or 3 hrs) all the edge switches are losing configuration automatically even though it's not restarted, even after saving the config on to nvram, everytime I connect the console and check all the saved config is lost?

Is there some special configration for configuring a mated/redundant pair of switches? or are they both just configured as though they were the same switch, but linked?

May 7, 2013I 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.

Cisco Switching/Routing :: 2960 / ME 3600 - Stack Switches Are Good Solution For Resilience Of Huge Network
May 8, 2012I have a question for Cisco Cat.2960-s Flex Stack switches which are installing on our sties. Two of 2960-s Stack switches as access switch and two of Cisco ME 3600X Series as distribution layer switches are to be installed in our sites. In case of two stack switches, One is will be a Master and the other one will be a member logically, as you know. So, if the master fails, the other one automatically becomes the stack master following a well-documented election process.
Now, it is my question. How long takes to be a stack master from a member switch ? I cant find it on white paper of Cat.2960-s flex stack .
And also, I heard that sometimes a member switches don't election process when the master fails as a result, all stack members become
a panic. Is that really right ? In addition, I heard that the stack switches have many troubleshooting points than stand alone switches.
I really wanna know if the stack switches are good solution for resilience of huge network site. I'm waiting an answer from those who have experience of maintenance or installation.
Cisco Switching/Routing :: 2960 No Internet Access From VLAN

Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 24 WS-C2960-24-S 15.0(1)SE2 C2960-LANLITEK9-M
[/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.
