Additional Information Power over Ethernet (PoE): Provide inline power to attached devices via industry-standard 802.3af Power over Ethernet (PoE). The internal power supply provides a power budget of 300 Watts, which is dynamically allocated to PoE ports. Security: 802.1X network access control MD5 cipher-text authentication and clear-text authentication for RIP v2 packets and SNMP v3 traffic RADIUS authentication ensures secure access to resources. Additionally, RADIUS Authenticated Device Access (RADA) enables authentication of attached devices via MAC address. Port-based Access Control Lists (ACLs) Secure Shell (SSHv2) and SNMPv3 support ensure secure management access to switches via authentication and encryption of management traffic.
