Advanced Features
The JL355A HPE Aruba 2540 48G 4 SFP Managed Desktop Switch offers a variety of advanced features that provide additional functionality and enhance network performance.
- Layer 3 Routing: The switch supports layer 3 routing protocols, allowing it to route traffic between VLANs and provide inter-VLAN communication. This allows the switch to be used as a router in addition to a switch and enables more advanced network topologies.
- Access Control Lists (ACLs): The switch supports Access Control Lists (ACLs), which can be used to restrict access to specific network resources. This feature provides granular control over network access, allowing network administrators to create security policies that are tailored to their specific needs.
- Virtual LANs (VLANs): The switch supports Virtual LANs (VLANs), which can be used to segment a network into separate, secure domains. This feature allows network administrators to create VLANs for different departments or groups, providing security and isolation between different parts of the network.
- Link Aggregation Control Protocol (LACP): The switch supports Link Aggregation Control Protocol (LACP), which allows grouping multiple ports together to form a single logical link. This increases bandwidth and provides redundancy in case of a failure on one of the physical links.
- Multiple Spanning Tree Protocol (MSTP): The switch supports Multiple Spanning Tree Protocol (MSTP), which allows multiple VLANs to share a single physical link while providing loop-free redundancy.
- Other advanced features such as IPv6, sFlow, and LLDP/LLDP-MED can also be used to enhance network performance, security, and manageability.
Access Control Lists (ACLs)
Access Control Lists (ACLs) is a feature of the JL355A HPE Aruba 2540 48G 4 SFP Managed Desktop Switch that allows network administrators to restrict access to specific network resources.
- Restrict Network Access: ACLs allow administrators to create rules that specify which types of traffic are allowed to enter or exit a network and which are denied. This feature provides granular control over network access, allowing administrators to create security policies that are tailored to their specific needs.
- Filter Traffic: ACLs can be used to filter traffic based on a variety of criteria such as IP address, port number, and protocol. This allows administrators to create rules that only allow specific types of traffic, such as web traffic or email, to enter or exit the network.
- Control Access: ACLs can be used to control access to specific network resources, such as servers or databases, by only allowing traffic from authorized IP addresses or subnets. This helps to prevent unauthorized access to sensitive data and network resources.
- Improve Security: ACLs can be used to improve security by blocking known attack signatures and preventing traffic from known malicious IP addresses or subnets.
- The JL355A HPE Aruba 2540 48G 4 SFP Managed Desktop Switch supports both IPv4 and IPv6 ACLs, and they can be applied on different layers such as L2, L3 and L4. The switch also supports advanced features such as time-based ACLs and reflexive ACLs to further enhance security and flexibility.
Power over Ethernet (PoE)
Power over Ethernet (PoE) is a feature of the JL355A HPE Aruba 2540 48G 4 SFP Managed Desktop Switch that allows devices such as wireless access points and IP phones to be powered through the Ethernet cable, eliminating the need for additional power sources.
- Power Delivery: PoE allows the switch to deliver power to devices over the Ethernet cable. This eliminates the need for separate power cables and outlets, making it easier to install and manage devices in locations that do not have easy access to power.
- Standards: The switch supports IEEE 802.3af and IEEE 802.3at PoE standards which provide different levels of power to devices. IEEE 802.3af delivers up to 15.4 watts of power per port, and IEEE 802.3at delivers up to 30 watts of power per port.
- Power Budget: The switch has a PoE power budget which allows network administrators to control the amount of power that is allocated to different devices. This helps to ensure that devices receive the power they need while avoiding overloading the switch's power supply.
- Energy-Efficiency: The switch also supports Energy-Efficient Ethernet (EEE), which reduces power consumption when the network is idle. This helps reduce the environmental impact of the switch and can also help lower energy costs.
- PoE can be used to power a variety of devices such as IP phones, wireless access points, security cameras, and other network devices which require power over Ethernet.
