When i connect two cisco 2960 series switchs via stright trough cable causes delay in transmission sw1 has vlans and having trunk port connected to router all vlans are able to access internet sw2 is connected to vlan5 on switch1 sw2 has factory default configuration computers on sw2 can access internet but I have low bandwith problem on sw2 there is transmission delay problem?
View 1 RepliesI have a Cisco Catalyst 2960 series switch. When I connect another switch or a VMWare Esx server on one of the ports, the port blinks for few seconds and then goes off. When I connect a desktop or laptop or a windows server the ports stay led and I can access resources on the network. However, when connect another switch or a vmware esx server, the port is disabled.
What config in the switch can I check to make sure the ports stay on regardless when I connect a desktop / laptop, switch or vmware server?

View 3 Replies View RelatedI 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 ?

I am planning on deploying a 2960 switch and will need to uplink it to a 4510 switch. There are 2 TenGig Ports available and I was thinking of uplinking one of them to the 1Gb SFP port on the 2960. Would this work?
View 4 Replies View RelatedI 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?
I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
I have two Cisco 48 port Catalyst 2960-S series SI. Instead of buying the pricy stack modules can I only use the SFP+cable to connect them as stack? which type of SFP+cable should I buy? do I need any license to use those SFP ports?

It doesnt like my password, but I have only set 1 password (king) on this switch. I've configured 3 other switches with SSH and had no problem. Been trouble shooting for awhile and It'd be great if I could have a 2nd set of eyes take a peek, Also, my running config is attached.
I am setting up a new 2960-S switch and none of the recommended username and passwords combinations work. I have tried CIsco Cisco, <blank> cisco and various other permutations.

Is it the right way ?Cisco 2960 is a Layer 2 or a Layer 3 Switch ? I noticed that access-lists could be configured which means that it 's a Layer 3 Switch , right?
