Equipment: Cisco three layer OneTP AC200 1 UnitsTP AP 2 unitsObjective: To set up multiple SSID signals, each of which is independent of one network segment, and the terminal obtains IP automatically.Difficulties encountered: According to TP description AP Port is added to the specified VLAN, while the SSID binding in AC corresponds to vid, but the wireless terminal can not obtain IP.Set up:Three-tier VLAN-

Label: State port so the network cannot switch port status multipleVSS uses the inter-chassis nsf/sso as the primary high-availability mechanism between the two enclosures. One Virtual Switch member chassis will be a member of the primary virtual switch, and another member will be in the hot wait state of the control Panel. The data panels for both enclosures are available, so the total traffic forwarding capability is 1440Gbps. When a virtual switch

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, config

Reason: The company panel interface is not enough, through the small Fool switch expansion interface . phenomenon: Small fool switch Connection panel, then computer connection small fool switch. Found that the computers are not ping gateway, but can ping each other . Description Small fool switch is no problem, the connection between the small fool switch and the original switch fails . View the original switch configuration and find the Portfast configured . and Spanning-tree Bpduguard enable i
