SGS-5240 series
– MSTP, IEEE 802.1s (Multiple Spanning Tree Protocol,
spanning tree by VLAN)
– Supports BPDU & root guard
• Port mirroring to monitor the incoming or outgoing trafc
on a particular port (many to one)
• Supports G.8032 ERPS (Ethernet Ring Protection
Switching)
• Loop protection to avoid broadcast loops
• Link Layer Discovery Protocol (LLDP)
• Compatible with Cisco uni-directional link detection
(UDLD) that monitors a link between two switches and
blocks the ports on both ends of the link if the link fails at
any point between the two devices
Quality of Service
• Input and output rate limit per port bandwidth control
• 8 priority queues on all switch ports
– IEEE 802.1p CoS/DSCP/IP Precedence
– VLAN ID
– ACL
– Policy-based ingress and egress QoS
Multicast
• Supports IPv4 IGMP snooping v1, v2 and v3
• Supports IPv6 MLD snooping v1 and v2
• Querier mode support
• IPv4 IGMP snooping port ltering
• IPv6 MLD snooping port ltering
• MVR (Multicast VLAN Registration)
Security
• Authentication
– IEEE 802.1x port-based/MAC-based network access
authentication
– IEEE 802.1x authentication with guest VLAN
– Built-in RADIUS client to cooperate with the RADIUS
servers
– RADIUS/TACACS+ users access authentication
– Guest VLAN assigns clients to a restricted VLAN with
limited services
• Access Control List
– IP-based Access Control List (ACL)
– MAC-based Access Control List (ACL)
– Time-based ACL
• DHCP snooping to lter distrusted DHCP messages
• Dynamic ARP Inspection discards ARP packets with
invalid MAC address to IP address binding
• IP Source Guard prevents IP spoong attacks
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. The IP Stacking
technology groups PLANET SGS-5240 switch series together to enable centralized
management through a single unit, regardless of physical location or switch type,
as long as they are connected to the same local network.

High Performance 10Gbps Ethernet Capacity
The four SFP+ slots built in the SGS-5240 series support dual speed and
10GBASE-SR/LR or 1000BASE-SX/LX. With its 4 ports, 10Gbps and 1Gbps
Ethernet link capability, the administrator now can exibly choose the suitable SFP/
SFP+ transceiver according to the transmission distance or the transmission speed
required to extend the network efficiently. The SGS-5240 Series provides broad
bandwidth and powerful processing capacity.
Redundant Ring, Fast Recovery for Critical Network Applications
The SGS-5240 series supports redundant ring technology and features strong,
rapid self-recovery capability to prevent interruptions and external intrusions. It
incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching)
technology and Spanning Tree Protocol (802.1s MSTP) into customer’s network
to enhance system reliability and uptime in harsh environments. In a certain simple
Ring network, the recovery time could be less than 50ms to quickly bring the
network back to normal operation.
