Redundancy and Resilience Features
The Cisco WS-CE520-8PC-K9 Catalyst Express SFP 520 Series 8 Ports Ethernet Switch includes various redundancy and resilience features to ensure that enterprise networks remain operational even in the event of a failure or network disruption. Some of the key redundancy and resilience features of the Cisco WS-CE520-8PC-K9 include:
- Link Aggregation Control Protocol (LACP): This protocol allows multiple physical links to be bundled together to form a single logical link, providing increased bandwidth and redundancy, as traffic can be automatically rerouted in the event of a link failure.
- Rapid Spanning Tree Protocol (RSTP): RSTP is a faster version of the Spanning Tree Protocol (STP) that allows the switch to quickly detect and recover from network topology changes, such as a failed link. This helps to ensure that the network remains operational even in the event of a failure.
- Hot Standby Router Protocol (HSRP): HSRP allows multiple routers to share a virtual IP address so that if the primary router fails, a secondary router can take over its responsibilities without interruption.
- Loop protection: The Cisco WS-CE520-8PC-K9 includes loop protection features that help prevent network loops from forming, which can cause network outages.
- Dual image support: The Cisco WS-CE520-8PC-K9 supports dual image, which means that two different firmware images can be stored in the switch memory. This allows for easy switchover in case of a firmware failure.
- Dual power supply support: The Cisco WS-CE520-8PC-K9 supports a dual power supply, which allows the switch to continue operating even if one of the power supplies fails.
Quality of Service (QoS) and Traffic Prioritization
The Cisco WS-CE520-8PC-K9 Catalyst Express SFP 520 Series 8 Ports Ethernet Switch includes Quality of Service (QoS) and traffic prioritization features to ensure that critical network traffic is given priority over less important traffic. Some of the key QoS and traffic prioritization features of the Cisco WS-CE520-8PC-K9 include:
- Class of Service (CoS): The Cisco WS-CE520-8PC-K9 allows you to assign different CoS values to different types of traffic. This allows you to prioritize certain types of traffic, such as time-sensitive voice or video traffic, over less critical traffic, such as email or web browsing.
- Weighted Round Robin (WRR) scheduling: This scheduling algorithm allows you to assign different weights to different traffic types so that higher-priority traffic is serviced before lower-priority traffic.
- Quality of Service (QoS) groups: The Cisco WS-CE520-8PC-K9 allows you to group ports and assign them a specific CoS value or WRR weight. This allows you to easily apply the same QoS settings to multiple ports at once.
- IEEE 802.1p: This standard allows you to assign different priority levels to different types of traffic based on the IEEE 802.1p priority tag.
- Link Layer Discovery Protocol (LLDP) and Cisco Discovery Protocol (CDP): LLDP and CDP allow the switch to discover other devices on the network and automatically apply QoS policies based on the device type.
These QoS and traffic prioritization features of the Cisco WS-CE520-8PC-K9 can be used to ensure that time-sensitive voice or video traffic is given priority over less critical traffic, such as email or web browsing. This helps to ensure that these applications receive the bandwidth they need to operate effectively, and reduces the risk of network congestion and delays.
Security and Access Control
The Cisco WS-CE520-8PC-K9 Catalyst Express SFP 520 Series 8 Ports Ethernet Switch includes various security and access control features to protect the network from unauthorized access and malicious attacks. Some of the key security and access control features of the Cisco WS-CE520-8PC-K9 include:
- IEEE 802.1X: This standard allows you to authenticate network users using a variety of methods, such as username and password, digital certificates, or biometric authentication.
- Port security: This feature allows you to configure security settings on a per-port basis, such as limiting the number of MAC addresses that can be learned on a port, or disabling a port if a security violation is detected.
- Access control lists (ACLs): ACLs allow you to define specific rules for controlling access to the network, such as allowing or denying traffic based on source and destination IP address, port number, or protocol.
- Dynamic Host Configuration Protocol (DHCP) snooping: DHCP snooping helps to prevent unauthorized DHCP servers from providing incorrect IP addresses to devices on the network.
- IP Source Guard: IP Source Guard helps to prevent unauthorized devices from connecting to the network by only allowing devices with a valid IP address to connect to the network.
- Statically configured MAC addresses: You can configure the switch to only allow specific MAC addresses to connect to the network, which helps to prevent unauthorized devices from connecting to the network.
- VLAN Access Control List (VACL): VACLs allow you to apply access control to traffic that is specific to a VLAN.
- Enhanced security for management access: The switch supports Secure Shell (SSH) and Secure Sockets Layer (SSL) for secure management access to the switch, and also supports secure management access via HTTPS.
