Users Manual of GPL-8000
Extractive Power Supply Design to Increase Flexibility
The GPL-8000 is equipped with one extractive 100~240V AC power supply unit, so it is easy to replace the power for
users. Besides, the GPL-8000 reserves another backup power slot on the rear panel and users can add the second AC or
DC power to the redundant power supply installation. The AC power or DC power is optional. The redundant power
system is specifically designed to handle the demands of high-tech facilities requiring the highest power integrity.
Layer 3 Routing Support
The GPL-8000 enables the administrator to conveniently boost network efficiency by configuring Layer 3 static routing
manually, the RIP (Routing Information Protocol) or OSPF (Open Shortest Path First) settings automatically.
- The RIP can employ the hop count as a routing metric and prevent routing loops by implementing a limit on the
number of hops allowed in a path from the source to a destination.
- The OSPF is an interior dynamic routing protocol for autonomous system based on link-state. The protocol creates
a link-state database by exchanging link-states among Layer 3 switches, and then uses the Shortest Path First
algorithm to generate a route table based on that database.
Robust Layer 2 Features
The GPL-8000 can be programmed for basic switch management functions such as port speed configuration, port
aggregation, VLAN, Spanning Tree Protocol, WRR, bandwidth control and IGMP snooping. It also supports 802.1Q
tagged VLAN, Q-in-Q and GVRP Protocol. In addition, the number of VLAN interfaces is 4K. By supporting port
aggregation, the GPL-8000 allows the operation of a high-speed trunk combined with multiple ports. It enables up to 32
groups for trunking with a maximum of 8 ports for each group.
Efficient and Secure Management
For efficient management, the GPL-8000 is equipped with console, Web and SNMP management interfaces.
With the built-in Web-based management interface, the GPL-8000 offers an easy-to-use, platform-independent
management and configuration facility.
For text-based management, it can be accessed via Telnet and the console port.
For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet
content at each session for secure remote management.
Moreover, the GPL-8000 offers secure remote management by supporting SSHv2, TLSv1.0 and SSLv3 connection which
encrypts the packet content at each session.
