What are two options to consider when configuring a trunk between two switches?
When configuring a trunk between two switches, two key options to consider are the trunking protocol and the encapsulation type. The most common trunking protocols are IEEE 802.1Q and Cisco's proprietary ISL (Inter-Switch Link), with 802.1Q being the widely accepted standard. Additionally, it's important to ensure that both switches are configured to allow the same VLANs across the trunk, which can involve specifying allowed VLANs or setting the trunk to carry all VLANs by default.
What do switches do?
A switch is a device that segments networks into different subnets. Segmenting the network into different subnets keeps one network from overloading with traffic. Therefore, a switch forwards all data in the data layer and sometimes the network layer as it filters the data. A switch allows a connection to be established and it terminates a connection when there is no longer a session to support. Prior to switches there were hubs. Hubs also connected multiple independent (connected) modules in a network, but they were not as efficient as switches. Since most switches work in Layer 2, and not in Layer 1 like a hub, they are better at filtering data. A switch looks for Ethernet MAC addresses, keeps a table (the bridge forwarding table) of these addresses, and navigates the switch between ports. The switch prevents collisions and gives full bandwidth to each connection at the switch port. Switches save bandwidth by only sending traffic to destinations that have traffic. When a switch switches Ethernet frames, they monitor the traffic for the response from that frame and see what device, on what port, responds to that flooded frame. There are different types of switches that range from "dumb" switches that lack manageability and can monitor only 4-8 ports to "managed" switches that can get statistics on switch traffic, monitor connections, and hard-code up to 96 port speeds and duplex. Then again, there are "chassis-based" switches with blades or cards that perform not just switching, but routing and intrusion detection too! If you are interested in this, look into Cisco's Catalyst 6500 Series. Another type of switch preferred by large enterprises is the "Layer 3 Switch," because it has the functionality of a router .
Why does a Cisco 2960g-24tc take some time to function properly?
The Cisco Catalyst 2960 must go through a few processes when it is first powered on. Like POST and loading the O/S and any configuration file that could be saved. After that is completed, depending on how it is configured, each active port will run through STP (Spanning Tree Protocol) to make sure there are no switching loops. Depending on which version is configured and how it could take up to 50 seconds for that port to go from a blocking state (no packet flow) to a forwarding state ( packet flow).
What command displays the configuration stored in NVRAM?
wr or copy running-config startup config
Where can one learn about CCIE lab equipment?
Someone can learn about CCIE lab equipment from a number of colleges and schools such as Humber College. Humber College offers a number of Cisco equipment courses on most of its campuses.
Where one can buy Cisco Catalyst switches?
If someone is looking to buy Cisco Catalyst switches, they may start by looking at Cisco's online catalog on their website. If Cisco doesn't have the selection the person is looking for, they may also check out Office Depot's website.
Do Cisco 2690 Catalyst Switches support 100-Base-T Speeds?
Yes, they do.
What cisco ios version is needed for mpls on a catalyst 3550?
Unfortunately MPLS is not supported on the C3550 switches.
What is the default value of bridge priority on cisco switches?
The default bridge priority on Cisco switches is 32768. This value is used in the Spanning Tree Protocol (STP) to determine the root bridge in a network. Lower bridge priority values are preferred, so if multiple switches have the same priority, the switch with the lowest MAC address becomes the root bridge.
Where can one find used Cisco switches?
The company Cisco sells their switches directly. The Cisco website has links to where one can purchase Cisco switches. Alternatively, Cisco switches can be purchased second-hand from online retailers such as Ebay.
Where is the ip address on a cisco switch for telnet?
The Cisco switches I have seen don't have an IP address by default. You have to connect to the switch with a console cable - one that connects to the console port on the switch, and to the serial port on the computer - and do some initial configuration, including the IP address.The Cisco switches I have seen don't have an IP address by default.

What is the default password to the Cisco 2611?
The factory default login and password on the Cisco 1721 router is Cisco. This is usually written in the manual of the router or somewhere in the packaging of the device.
What is the use of console port in cisco switches?
Like Cisco routers, most Cisco switches run IOS, and can be configured in a similar way. Older non-IOS switches still use the console port to configure them, just like the routers.
Why types of hardware products does CISCO manufacture?
CISCO is widely known for its networking hardware products such as routers, modems, and switches. Some of CISCO's other hardware products are blade server switches, data center switches, and optical networking hardware.
Where can one purchase Cisco 6500 switches?
One can purchase Cisco 6500 switches when one goes to the official website of Cisco. One can also purchase from other sites like Vista, Amazon, and eBay, etc.
Is cisco discovery protocol enabled by default on Cisco Aironet Bridges and Access Points?
Yes
Why does the cisco catalyst 2960 not well known?
On the contrary, the Cisco Catalyst 2960 is a very well-known product. This switch is widely used in many small businesses. There are few which are unhappy with this switch.
