Page 12: Product Description
High Reliability Hardware Stacking Two of the 10G SFP+ ports are used to connect several SGS-5240 series, enabling to build a virtually logical facility. The SGS-5240 series gives the enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance.
Page 13 Central IP Stacking Management Positioned as the distribution or aggregation layer switch for large networks, the SGS-5240 series supports IP stacking function that helps network managers to easily configure up to 16 switches in the same series via one single IP address instead of connecting and setting each unit one by one.
Page 14 Powerful Network Security The SGS-5240 series offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications.
Page 15 User’s Manual of SGS-5240 Series Managed Switch Moreover, the SGS-5240 series offers secure remote management by supporting SSHv2 and SSLv3 connection which encrypts the packet content at each session. Intelligent SFP Diagnosis Mechanism The SGS-5240 series supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

User’s Manual of SGS-5240 Series Managed Switch APPENDIX B : GLOSSARY ACE is an acronym for Access Control Entry. It describes access permission associated with a particular ACE ID. There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions (permit and deny). The ACE also contains many detailed, different parameter options that are available for individual application.
Page 293 User’s Manual of SGS-5240 Series Managed Switch Aggregation Using multiple ports in parallel to increase the link speed beyond the limits of a port and to increase the redundancy for higher availability. (Also Port Aggregation, Link Aggregation). ARP is an acronym for Address Resolution Protocol. It is a protocol that used to convert an IP address into a physical address, such as an Ethernet address.
Page 294 User’s Manual of SGS-5240 Series Managed Switch DHCP Relay DHCP Relay is used to forward and to transfer DHCP messages between the clients and the server when they are not on the same subnet domain. The DHCP option 82 enables a DHCP relay agent to insert specific information into a DHCP request packets when forwarding client DHCP packets to a DHCP server and remove the specific information from a DHCP reply packets when forwarding server DHCP packets to a DHCP client.

IMAP IMAP is an acronym for Internet Message Access Protocol. It is a protocol for email clients to retrieve email messages from a mail server.
Page 297 User’s Manual of SGS-5240 Series Managed Switch LOC is an acronym for Loss Of Connectivity and is detected by a MEP and is indicating lost connectivity in the network. Can be used as a switch criteria by EPS MAC Table Switching of frames is based upon the DMAC address contained in the frame.
Page 298 User’s Manual of SGS-5240 Series Managed Switch NFS is an acronym for Network File System. It allows hosts to mount partitions on a remote system and use them as though they are local file systems. NFS allows the system administrator to store resources in a central location on the network, providing authorized users continuous access to them, which means NFS supports sharing of files, printers, and other resources as persistent storage over a computer network.
Page 299 User’s Manual of SGS-5240 Series Managed Switch An alternative protocol is Internet Message Access Protocol (IMAP). IMAP provides the user with more capabilities for retaining e-mail on the server and for organizing it in folders on the server. IMAP can be thought of as a remote file server.

Ports connected to subscribers are VLAN unaware, members of one VLAN, and set up with this unique Port VLAN ID. Ports connected to the service provider are VLAN aware, members of multiple VLANs, and set up to tag all frames.
Page 304 User’s Manual of SGS-5240 Series Managed Switch WRED WRED is an acronym for Weighted Random Early Detection. It is an active queue management mechanism that provides preferential treatment of higher priority frames when traffic builds up within a queue. A frame's DP level is used as input to WRED.
