Description
Advanced Networking Capabilities
The Cisco Catalyst 3850 Series 24-Ports UPoE Layer 3 Switch (WS-C3850-24U-E) offers advanced networking capabilities that enable efficient and reliable communication within the network.
One of its key features is its support for IPv4 and IPv6 routing protocols, such as Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP). This allows for dynamic routing and efficient use of network resources, and enables communication between different network protocols.
The switch also supports advanced features such as Link Aggregation Control Protocol (LACP) and Quality of Service (QoS) which allows for load balancing across multiple links and prioritization of different types of network traffic, respectively.
It also supports Cisco StackWise-480 technology which enables the switch to be stacked with other Cisco Catalyst 3850 switches to create a single, virtual switch, providing increased scalability, resiliency, and ease of management.
In addition, the switch supports Cisco Application Visibility and Control (AVC) which allows for granular visibility and control of applications running on the network, and Cisco TrustSec which enables secure access to the network.
Power Options and Redundancy
The Cisco Catalyst 3850 Series 24-Ports UPoE Layer 3 Switch (WS-C3850-24U-E) offers advanced power options and redundancy features that ensure the switch can continue to operate in case of power failure or other issues.
One of its key features is its support for Power over Ethernet (PoE) and uplink Power over Ethernet (UPoE), which allows the switch to power connected devices, such as wireless access points and IP phones, eliminating the need for additional power sources.
The switch also supports Cisco StackPower, which allows multiple switches to share power supplies and provide power redundancy in case one of the power supplies fails. Additionally, it supports Cisco StackWise-480 technology, which enables the switch to be stacked with other Cisco Catalyst 3850 switches to create a single, virtual switch, providing increased scalability, resiliency and ease of management.
The switch also supports redundant power supply options, which allows the switch to continue to operate even if one of the power supplies fails. This can help to ensure that the network remains up and running even in the event of a power failure.
Access Control Lists (ACLs) for Security
Access Control Lists (ACLs) are a security feature that can be used to control network access on a Cisco Catalyst 3850 Series switch, such as the WS-C3850-24U-E model. These switches support both standard and extended ACLs, which can be applied to both inbound and outbound traffic.
Standard ACLs use only the source IP addresses to filter traffic and are typically used to allow or deny access to a specific network or host. They are identified by a number between 1 and 99 or 1300 and 1999. For example, an ACL named “10” would be used to allow all traffic from the 10.0.0.0/8 network.
Extended ACLs, on the other hand, use a combination of source and destination IP addresses, as well as other criteria such as protocol and port number, and are more flexible in filtering traffic. They are identified by a number between 100 and 199 or 2000 and 2699. For example, an ACL named “100” would be used to allow all HTTP traffic from the 10.0.0.0/8 network to the 192.168.0.0/16 network.
To configure an ACL on a Cisco Catalyst 3850 Series switch, you will need to use the command-line interface (CLI) and follow these basic steps:
- Create an ACL: create a named list of permit or deny statements
- Apply the ACL to an interface: specify the direction of traffic and the interface where the ACL will be applied
- Verify the ACL configuration: check if the ACL is working as expected
