WS-C3850-48T-S Cisco Catalyst 3850 48 Ports L3 Managed New

Security Features

The WS-C3850-48T-S Cisco Catalyst 3850 48 Ports L3 Managed Switch offers several advanced security features to protect your network against various security threats. Some of the security features of the switch are:

• IEEE 802.1X: The WS-C3850-48T-S switch supports IEEE 802.1X, which provides port-based access control. It authenticates devices that try to connect to the network and allows only authorized devices to access the network. This helps prevent unauthorized access to the network and ensures that only trusted devices can connect to the network.
• Access Control Lists (ACLs): The switch also supports Access Control Lists (ACLs), which allow you to control the flow of traffic based on various criteria such as source and destination IP addresses, protocols, and port numbers. You can use ACLs to block unwanted traffic and prevent network attacks such as DoS attacks and port scanning.
• Port Security: The WS-C3850-48T-S switch supports port security, which allows you to limit the number of MAC addresses that can connect to a particular port. This helps prevent unauthorized devices from connecting to the network and ensures that only authorized devices can access the network.
• Dynamic Host Configuration Protocol (DHCP) Snooping: The switch supports DHCP snooping, which prevents rogue DHCP servers from assigning IP addresses to devices on the network. DHCP snooping also ensures that only authorized DHCP servers can assign IP addresses, preventing IP address conflicts and unauthorized access to the network.
• IP Source Guard: The WS-C3850-48T-S switch supports IP source guard, which prevents IP address spoofing. IP source guard ensures that only valid IP addresses can connect to the network, preventing attackers from spoofing IP addresses and launching attacks such as man-in-the-middle attacks.
• MACsec Encryption: The switch also supports MACsec encryption, which provides secure communication between devices over the network. MACsec encryption ensures that data is encrypted at the MAC layer, providing an additional layer of security for your network.

Deployment Scenarios

The WS-C3850-48T-S Cisco Catalyst 3850 48 Ports L3 Managed Switch is a versatile switch that can be deployed in various network environments. Some of the deployment scenarios for this switch are:

• Campus LAN: The WS-C3850-48T-S switch is ideal for campus LAN environments, where it can provide high-speed connectivity and advanced features such as Quality of Service (QoS), VLANs, and advanced security features.
• Data Center: The switch can also be deployed in data center environments, where it can provide high-density 1G and 10G connectivity and advanced features such as Virtual Port Channel (vPC), Layer 3 routing, and Application Visibility and Control (AVC).
• Branch Offices: The WS-C3850-48T-S switch can be deployed in branch offices where it can provide high-speed connectivity and advanced features such as Power over Ethernet (PoE) and Energy Efficient Ethernet (EEE).
• IP Surveillance: The switch can also be deployed in IP surveillance environments where it can provide PoE+ connectivity to cameras and support for advanced features such as MACsec encryption and IEEE 802.1X authentication.
• Wireless LAN: The switch can also be deployed as a wireless LAN controller (WLC) in converged wired and wireless access networks. It can provide advanced wireless features such as Wireless LAN Controller (WLC) functionality, RF management, and Quality of Service (QoS).

Troubleshooting Common Issues

The WS-C3850-48T-S Cisco Catalyst 3850 48 Ports L3 Managed Switch is a high-performance switch with advanced features. However, like any network device, it may encounter issues from time to time. Here are some common issues and troubleshooting steps that can help resolve them:

• Network Connectivity Issues: If the switch is unable to connect to the network, check the network cables and ensure that they are connected properly. Verify that the network port is enabled, and check the configuration settings to ensure that they are correct. If the issue persists, try connecting the switch to a different network port or switch.
• VLAN Configuration Issues: If VLANs are not functioning as expected, check the VLAN configuration settings and ensure that they are configured correctly. Verify that the VLANs are tagged and untagged correctly, and ensure that the switch ports are configured for the correct VLAN.
• Performance Issues: If the switch is experiencing performance issues such as slow data transfer rates, check the switch configuration settings and ensure that they are optimized for performance. Check the CPU and memory utilization, and verify that the switch is not experiencing any bottlenecks.
• Security Issues: If the switch is experiencing security issues such as unauthorized access, check the security settings and ensure that they are configured correctly. Verify that the access control policies are in place and that the security features such as port security, MACsec encryption, and IEEE 802.1X authentication are enabled.
• Power Issues: If the switch is not receiving power or is experiencing power-related issues, check the power supply and ensure that it is working correctly. Check the power cord and ensure that it is connected properly. If the switch is not receiving enough power, check the power requirements and ensure that the power supply is capable of providing the required power.
• Firmware Issues: If the switch is experiencing firmware issues such as boot failures or crashes, check the firmware version and ensure that it is up to date. If the issue persists, try reinstalling the firmware or contact the technical support for assistance.
