A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core switch through the light module of port 1; assu
port) is not connected to the network cable. You can manually close the ALARM of the Management port and use this command in juniper: # Set chassis alarm management-ethernet link-down ignore # Commit The light gradually becomes orange. Add another command # Set chassis alarm ethernet link-down ignore # No alert is generated when you set all ports (Note: link-down can detect the port status. If you have set an alarm for Port link down, it is best to disable unused ports to avoid frequent alarms.

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You can also limit some ports, policy to restrict some ports. I. Network Description User‑pc1 i

, Trunk can restrict the traffic to be transmitted only on the corresponding relay link by means of pruning. The impact of dozens of trunks on the core switch is far smaller than that configured with dozens of Route tables. Generally, the core switch can withstand dozens of trunks. You can limit the one-way speed of the port to make full use of the bandwidth in the other direction. This is especially useful

The minimum/maximum number of 10 M Ethernet ports is the minimum/maximum number of 10 M Ethernet ports supported by a vswitch. The minimum/maximum number of M Ethernet ports is the minimum/maximum number of M Ethernet ports supported by a
parameter runs normally. Otherwise, if this parameter is set incorrectly, problems may occur during the next startup. For the sake of security, it is best to back up the content in NVRAM before copying the running configuration file to NVRAM. This is mainly because when the copy running-config startup-config command is used, the command will automatically overwrite the startup configuration file at the tar
a hardware environment, we mainly listen to your opinions and see if there are any reasonable solutions to make the network safer and easier to manage. It should be a simple vlan division. However, your server is in a separate subnet. If your previous desktop computer uses dhcp, it will be allocated as a vlan. Because it cannot be broadcast across CIDR blocks, the desktop computer can only specify an ip address. This is not the case either. DHCP can also be REALAY. now, modify the DHCP server a
