Nov 18, 2011If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?

Nov 14, 2011If I have two stackable switches were only one stackable switch has two uplinks one uplink goes to one core 6509 switch and the other uplink goes to the other 6509 core switch can a Layer 3 etherchannel be used if each uplink go to a different core switch, by the way hsrp is running between both switches and also can you give an example how data will be routed from the stackable switch through the ethernetchannel to one of the core switch accross the WAN to another core switch?

Nov 14, 2011If I have two stackable switches one that connects to the 6509 core switch and the other switch does not, do I have to uplink the switch to the other switch so that switch has route to the core switch or because the switches are daisy chain there is not need to cable one switch to to the other switch connected to core switch?

May 6, 2013can you stack a 3750 switch over fiber.....the answer is no, but the virtual switching supervisor 720-10G for the 6500 can create one virtual switch using two 6500s...
how can we get cisco to come up with a way for access switches to be stacked over fiber similar to above supervisor? i know of few of my site that would benefit from this...maybe they can come up with a vss appliance, similar to a media converter, to convert stackwise over fiber...then of course, you would need the same appliance on the other end....

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)

Cisco Switching/Routing :: QoS In L2 Switches 2960 And 4500?
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?

View 2 Replies View RelatedCisco Switches :: SG500-28 Stackable Switches And NIC Teaming
Apr 17, 2012Am looking into using stacking and NIC teaming to create redunancy for user access to servers. What I am thinking is getting 2 SG500-28 switchs and configuring them in a stack that appears as one logical switch. Now on the servers I would configure 2 NICs to be a team so they appear as 1 logical interface, perferably in an active/active configuration using LACP. In this NIC team take 1 team member to switch A and the other to switch B, so each team member is on seperate switches.
Givent the scenario:
1) Will that work with the 500 series switchs? Reason for the switches is their price point is perfect for my client.
2) Besides the stack link will there also need to be a LAG between the switches or does the stack link do data traffic also?
Cisco Switching/Routing :: Fiber Connection Between Two 2960 Switches?
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?
