Principles of the DHCP simulation feature

7

In Dynamic Host Configuration Protocol (DHCP) simulation, IP address application from the DHCP server is performed by simulating a DHCP client on the access node instead of by using a real client. DHCP simulation tests network connectivity between the access node and DHCP server and verifies the DHCP configurations on the DHCP relay, DHCP proxy, and DHCP server. It also verifies the connectivity between the access node and remote services by pinging a remote server.

Principles of HSB
The AR supports the HSB function. HSB implementation involves data synchronization and traffic switching. Data synchronization is performed to ensure consistent information on the master and backup devices when the two devices are working normally. Traffic switching is performed to ensure non-stop service forwarding when the master device fails or recovers. The principle for data synchronization is to establish active and standby channels between devices that back up each other. Session entries of the master device can be synchronized to the backup device through the channel at one time, in real time, or periodically. The principle for traffic switching is based on negotiation between the master device and the backup device using VRRP. When the master device fails, a new master device is elected based on VRRP priorities and the traffic is switched to the master device.

Principle of BSSID generation
Centralized BSSID management allows an AC to automatically assign a unique BSSID to each VAP. You only need to configure a carrier ID and an AC ID for an AC. Then the AC automatically assigns a BSSID to each VAP. The BSSID allows you to rapidly locate a VAP on a network. A BSSID is generated based on the AC ID, carrier ID, and WLAN ID.

OTN principles
An OTN is a network consisting of optical NEs that are connected through optical fibers. It can transmit, multiplex, route, manage, monitor, and protect client signals on optical channels. A main feature of the OTN is client independence. That is, the transmission and configuration of any digital signals are irrelevant to the features of a client. OTN has the following advantages over traditional SDH: More powerful forward error correction, Tandem connection monitoring (TCM) at more levels, transparent transmission of client signals, and scalable switching capacity.
