Step 2: If ARP resolution is not there in local cache, the source machine will generate an Address Resolution Protocol (ARP) request message, it puts its own data link layer address as the Sender Hardware Address and its own IPv4 Address as the Sender Protocol Address. It fills the destination IPv4 Address as the Target Protocol Address. The Target Hardware Address will be left blank, since the machine is trying to find that. Step 3: The source broadcast the Address Resolution Protocol (ARP) request message to the local network. Step 4: The message is received by each device on the LAN since it is a broadcast.

Current best practices recommend IP Precedence 5, PHB AF41, DSCP 34, and CoS 4 for videoconferencing traffic. * Determine the impact on affected switches. * Verify that no noticeable change results in network traffic patterns or application performance. * Configure constituency and aggregation switches for IST subnets to use priority queuing (with a combined total bandwidth of no more than 1/3 the available bandwidth on any link for all priority traffic) for videoconferencing traffic in addition to queuing, policing and shaping configuration applied in Phase
