sfp switch 8 port

bandwidth description: When the Ethernet frame is 64 bytes, the fixed overhead of the 8 byte frame header and the 12 byte frame gap must be considered. Therefore, the packet forwarding rate of A 1-gigabit Ethernet port when forwarding a 64-byte packet is 1.488 Mpps. The 10-in-10 Gigabit Ethernet packet forwarding rate is 148.8 kpps.◆ For 10-Gigabit Ethernet, the packet forwarding rate of a wire speed

When maintaining the dormitory network for a few days, I encountered a very unique problem at the time: No matter how the 20 Ports of the vswitch on the fourth floor are connected, the link cannot be connected; when the switch enters, the port cannot be enabled; there is no problem connecting to other ports. I thought it was because the port broke down. Later I h

one thousand m switch. In general, the price of the desktop Gigabit Switch is still relatively approachable, making it possible for small offices to speed up in an all-round way, the cheapest Gigabit desktop switch costs only a few hundred yuan, which is very affordable. These products also have some characteristics in parameter indicators. The most important pa

zabbix to monitor switch traffic. Instead, cacti is used. In fact, there is a problem with cacti, but you didn't meet it !!! The reason is that the data monitored by cacti is larger than that monitored by zabbix. The two sides are inconsistent. Back to question In fact, to monitor the traffic on the vswitch port, pay attention to the two details. 1. The data unit is bit or bytes. This concerns the issue of

bound IP and Mac (2) 1 port next to a small switch binding mode such as: 1th ports under a 8-port access to a small switch, the switch has 3 computers, 3 computer IP and Mac as follows 1 Computer's ip:10.100.11.2 mac:00-1a-4d-

allow a maximum of 8 ports to be bound. If it is a 100Mbps port, it can reach 800mbit/s after aggregationif it is 1000Mbps Port, up to 8gbit/s after aggregationtwo-layer interface cannot be configured IP address, cannot announce route by agreement, only two layer Ethernet frame forwarding. the three-tier interface can be configured with IP addresses, can run rou

If there is no port aggregation on the switch. Your two computers are connected by two wires. is a loop, and it affects both the switch and the connected computer. Therefore, the port aggregation function is very important for the Internet Café switch. Provides a brief over

; # Returned KermitTo connect to the serial port again, enter connect Or c. 7. Download an object For example, download the Kernel File/home/liuby/uImage: First, make sure that KermitConnect to the serial port, that is, the start is the input Kermit-C Or connect to the serial port; Enter loadb 0x200000 in the u-boot command line; Then press ctrl +/, and then pres

If there is no port aggregation on the vswitch. Your two computers are connected with two network cables. It turns into a ring, which affects both the switch and the connected computer. Therefore, the port aggregation function is crucial for Internet cafe switches. This section briefly describes information about the port
