What are the features of PAP and CHAP

1

PAP is short for Password Authentication Protocol. It supports 2-way handshake and transmits the password in plain text. The peer end controls the connection request. PAP cannot effectively prevent attacks.

CHAP is short for Challenge Handshake Authentication Protocol. It supports 3-way handshake and transmits the password in cipher text. CHAP effectively prevents repeated trial-and-error attacks.

How can I configure PAP and CHAP authentication on the DCC
(C-DCC) On the calling party, if DCC is enabled on physical interfaces, configure PAP or CHAP authentication on the physical interfaces; if DCC is enabled for the dialer circular group, configure PAP or CHAP authentication on the dialer interface. Therefore, on the called party, you are advised to configure PAP or CHAP authentication on both physical interfaces and the dialer interface. When a physical interface receives a DCC request, it starts PPP negotiation and verifies the identity of the calling party, and then forwards the DCC request to the DCC module. (RS-DCC) The RC-DCC set does not apply attribute information such as the PPP authentication command to the physical interfaces. You must configure authentication information on the physical interfaces on the called party. You must configure the dialer user and PPP authentication simultaneously on the dialer interface and physical interfaces. RS-DCC requires PPP negotiation using the physical interfaces and delivers the negotiated peer end user name to the DCC after negotiation. The DCC then determines the dialer interface based on the peer end use name and returns the dialer interface address to PPP. PPP allows the physical interfaces to perform IPCP negotiation based on the dialer interface configuration.

How to Manage CHAP Users in FusionStorage
On FusionStorage, choose Resource Pool > Volume Management > iSCSI Volume Mapping. The iSCSI Volume Mapping page is displayed. Choose CHAP Users in the right pane. Locate the row that contains the CHAP user whose password is to be reset, and click Change Password in the Operation column. The Change Password page is displayed. Enter the new password and confirm password, and click Modify. A warning box is displayed. Click OK. Query the CHAP user of an initiator. On FusionStorage, choose Resource Pool > Volume Management > iSCSI Volume Mapping. The iSCSI Volume Mapping page is displayed. Choose Initiators in the right pane. Locate the row that contains the initiator whose CHAP users are to be queried, click More in the Operation column, and select View Added CHAP Users. The View Added CHAP Users page is displayed, showing information about the queried CHAP user. No further action is required. Delete a CHAP user from an initiator. On FusionStorage, choose Resource Pool > Volume Management > iSCSI Volume Mapping. The iSCSI Volume Mapping page is displayed. Choose Initiators in the right pane. Locate the row that contains the initiator from which a CHAP user is to be deleted, click More in the Operation column, and select Delete Incoming CHAP. The Delete Incoming CHAP page is displayed. Select the CHAP user to be deleted and click OK. The Initiators page is displayed, and the CHAP user is successfully deleted. No further action is required.

What are the features of SSDs for S5500T V1R5?
A solid state drive (SSD) comprises controlling unit and solid state unit. The SSD and the hard disk drive (HDD) have the same interface specifications, definition, functions, and using methods. They are also similar in the form factor and dimensions. The difference is that the SSD has no mechanical part. The SSD has NAND Flash as the storage medium and the data stored on it is accessed through being written and erased in blocks. The SSD has no mechanical latency caused by the disk media or driving motor as the HDD does; therefore, it has higher performance, lower power consumption, better shock-resistance ability, and better stability.
