tested are much smaller in size than their powerful forwarding capabilities, especially the DGS-3308TG switches of the digital D-link, which are highly functional and three-tier switches. The installation of Gigabit Ethernet backbone switches is not a matter of effort, physically or mentally. The gigabit backbone switches we tested, DGS-3308TG, Edimax es-5800r and 3Com 4900 switches all have 1000BASE-T interfaces. These switch 1000BASE-T interfaces are able to support the 10/100/1000m rate of

transmission bandwidth. Both of these methods support stacked redundant connections, respectively. When using daisy-chained connections, redundant connections are made by connecting the top switch to the bottom switch with a stacked cable. When point-to-point connection is used, it is accomplished by using the 2nd 3508 switch. 3, a Gigabit Catalyst3550 XL using a stacked card stack, another gigabit can be connected to gigabit switches or gigabit servers? OK. Need to use the 1000BASE-SX

BGP experiment, you can even use this configuration to establish full-network connectivity, and then create a tunnel port to implement the experiment topology. During remote configuration, you can save multiple configuration files and switch between them. The configuration file named router-confg can be used as a final backup-if you accidentally delete the configuration, there will still be an available configuration after the system restarts.Conclusion: The initial enchanting phenomenon is cau

The DGS-3308TG Gigabit Ethernet switch has two GBIC interfaces. the GBIC module can adapt to single-mode and multi-mode optical fiber.

for cascade between backbone switches. Note that all optical fiber ports are not stacked and can only be used for Cascade. Optical jumper crossover Each vswitch has two fiber-optic ports, one for one request. Of course, the optical fiber jumper must also be two; otherwise, communication between ports fails. When a vswitch is cascade through an optical fiber port, both ends of the optical fiber jumper must be sent and received. When one end is "received", the other end is "sent ". Similarly, whe

Optical Switch Port Cascade Because Fiber ports are still very expensive, fiber cables are mainly used for connection between core switches and backbone switches, or for cascade between backbone switches. Note that all optical fiber ports are not stacked and can only be used for Cascade. Optical jumper crossover Each vswitch has two fiber-optic ports, one for one request. Of course, the optical fiber jumper must also be two; otherwise, communication between ports

One point about AVAYA P333R is to configure a user to buy AVAYA P333R as the access switch, Gigabit Optical Fiber access, configure an X330G2 module, and connect a GBIC and a single-mode module for access, A Multimode module connects the local network to the central switch. The remote IP address is 10.10.10.1/255.255.255.0, the local access address is 10.10.10.2/255.255.255.0, the Local intranet address is 192.168.0.253, the center switch address is 1
