the first thing that I don't understand is why the SMC switch considers the pair of single mode fibers as one port,one link, but the HP switch sees the two fibers as two ports.
when I wanted to configure the link from the SMC, I use : eth 1/1 for example.from the HP it was eth 1/11 and 1/12.
I have set the interface eth 1/1 duplex mode and speed to Auto and negotiate.
My office recently opened a new branch, to which network connectivity was provided via fiber optic line and a cisco switch. From there onwards vis UTP cable and unmanageable (and admittedly not-so-high-quality) switches.
Everything worked fine for a few days, but recently, during certain time of the day (usually early afternoon and late evening) the connectivity to certain sections drop.
I need some help, I want to monitor the DGS-1024D which is a business grade d-link switch.
I have no current way of knowing if any of these have IP addresses on the switch or if there is away to monitor the switches.
I have 6 Juniper switches (EX - 2200) connected to each other as shown in the network topology below.
I have two PC's that I am using
PC1 - (used for configuring the 6 switches via minicom) PC2 - to monitor the traffic between the switches via the Ports that are marked with arrows in the diagram.
STEP 1:
I create a new vlan On Switch 3 (SW3) that includes Port 12 and Port 22.
I also assign l3-
I'm trying to replace an old Cisco Catalyst 2950 with a new Cisco 3750X. Unfortunately, these SFP's are so expensive, I'm trying to work with what I've got. Please note the diagram to see what connections I have. The core switch is SX, as is the old switch it was running to.
I'm using Pulseaudio. The image is of the Output Devices tab and shows the Port set to Analog Output. This is fine and works great. There's another option called Headphones but if you try and set the Port to Headphones it automatically switches back to Analog Output.
Configuring Cisco switches is much easier to routers. Layer 3 switches are designed to route packets between different LAN segments similarly to dedicated routers. However, Layer 3 switches do not completely replace the need for routers on a network. How to configure a Cisco layer 3 switch?...
In order to migrate to a new rack inside the datacenter I have to replicate the VLAN setup between a Cisco Switch and a Dell PowerConnect Swithch.
On the Dell Switch I have 2 VLANs :
vlan 10 : WAN
vlan 20 : MGMT
On the Cisco Switch i have created the same VLANs and set up different port range
vlan10 : Ports 1-12
vlan20 : Ports 13-24
Like this example:
interface gigabitethernet2
I have three switches I'd like to configure in a loop - a Cisco stack (3750s) and two HP 2900 series. Each is connected to the next with a 10 gig backplane of one form or another.
How do I configure the spanning tree on these systems to make this function correctly?
