Enhanced Security
The XGS-5240-24X2QR 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 application. Their
protection mechanism also comprises 802.1x Port-based and MAC-based customer and device
authentication. As to private VLAN function, communications between edge ports can be protected
to ensure customer privacy. The XGS-5240-24X2QR also provides functions of DHCP snooping,
Option 82 and ARP guard, and Anti-ARP scanning so as to prevent IP from attacking and
discarding ARP packets with invalid MAC address. The network administrators can now construct a
highly-secure corporate network with considerably less time and effort than before.
IPv6/IPv4 Dual Stack
As the XGS-5240-24X2QR supports the IPv6 Protocol, they help SMBs and enterprises to step in
the IPv6 era with the lowest investment, meaning the existing network facilities need not be
replaced.
Intelligent SFP Diagnosis Mechanism
The XGS-5240-24X2QR supports SFP-DDM (Digital Diagnostic Monitor) function that greatly
helps network administrator to easily monitor real-time parameters of the SFP, such as optical output
power, optical input power, temperature, laser bias current, and transceiver supply voltage.
