Four modes for managing routing and switching devices-SSH

As a network manager, it is the most common task to configure commands on routers and switches. The purpose is to execute commands and adjust parameters, allows routers and switches to run as required by network administrators. This is almost the operation performed by the network administrator every day. Which of the following methods can be used to manage network devices? Which one is simpler and which one is more efficient? This is mainly based on the actual use of the network administrator.

Four modes for managing routing and switching devices-telnet

Use Telnet to manage network devices This management mode requires the configuration of commands on the routing and switching devices, which is less than the command configured in the SSH management mode. The following figure uses the topology of Figure 1 as an example to configure the vswitch so that you can manage the PC and use Telnet to manage the configuration of Cisco 4506. The management VLAN 20 conf

frames, and potentially causing unrecoverable errors when critical.MAC Address Table jitter: that is, the MAC address table is unstable because copies of the same frame are received on different ports on the switch. If the switch consumes resources on a copy-unstable MAC address table, the data forwarding function may be weakened."Port cost" network access to the switch model is various, the same switch different ports its rate performance is not consistent, so the data from a device to B devic

"Ti layman" network knowledge note Three remote login configuration for Cisco routing switching

After the new switch is bought, all need to be simple configuration to meet the unit network operation, after the configuration of the device will need to put it where it should be placed, but in the future we need to view or modify this device, we need to use remote login to configure it. Let's talk about the specific configuration of remote login.First, you need to use a dedicated configuration line (console line) to connect the deviceSecond, configure the line of another section of the connec
