SMC Networks SMC2555W-AG manual Syntax Multicast-cipher AES Tkip WEP

Interface Commands

multicast-cipher

This command defines the cipher algorithm used for broadcasting and multicasting when using Wi-Fi Protected Access (WPA) security.

Syntax

multicast-cipher <AES TKIP WEP>

•AES - Advanced Encryption Standard

•TKIP - Temporal Key Integrity Protocol

•WEP - Wired Equivalent Privacy

Default Setting

WEP

Command Mode

Interface Configuration (Wireless)

Command Usage

•WPA enables the access point to support different unicast encryption keys for each client. However, the global encryption key for multicast and broadcast traffic must be the same for all clients. This command sets the encryption type that is supported by all clients.

•If any clients supported by the access point are not WPA enabled, the multicast-cipher algorithm must be set to WEP.

•WEP is the first generation security protocol used to encrypt data crossing the wireless medium using a fairly short key. Communicating devices must use the same WEP key to encrypt and decrypt radio signals. WEP has many security flaws, and is not recommended for transmitting highly sensitive data.

•TKIP provides data encryption enhancements including per-packet key hashing (i.e., changing the encryption key on each packet), a message integrity check, an extended initialization vector with sequencing rules, and a re-keying mechanism.
