what tests will you perform?
An administrator for ABC Company has noticed an intermittently high number of retransmissions on their ERP WLAN. The retransmissions are coming from some of the access points near the break room, especially when wireless stations are using the FTP protocol to pull down large sales report data files from the company’s FTP server. The administrator decides to hire you as a consultant hoping you could improve performance of the WLAN. As the consultant, what tests will you perform?
What is the best way for the network administrator to gather call setup and jitter VoIP statistics for the wir
Given: ABC Company has a VoIP implementation in place over the Ethernet network at their facility. To watch for anomalies and to monitor statistics of VoIP phone calls, ABC Company’s administrator has configured a set of VoIP filters on their distributed Ethernet protocol analyzer. ABC Company has recently installed a dual-band IEEE 802.11 controller-based WLAN system (with lightweight APs) that is configured for WMM and WPA2-Enterprise and a wireless intrusion prevention system (WIPS). Considering the CCMP/AES encryption used on the WLAN segment, ABC Company’s administrator knows that no Layer 3-7 data will be available via their WIPS.
