It is unclear why Cisco retains this secret because it has learned that Password 7 encryption is very easy to crack. Then, enter the statement to change the logon password in the file: Line vty 0 4 password New * Passwo

downstream interfaceLimit rate speed, calculated as follows:assuming that 2960 is the port, so the simple set speed limit is*15=720 Note: IP DHCP snooping limit rate needs to be set only if the DHCP snooping converged switch or core is enabled. If there is a large number of access layer switches under a core or aggregation switch, the speed limit setting needs to be noted because the maximum limit rate for the port is 2048, soyou need to adjust the limit rate on the access layer port to make

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so t

Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting
