210 Troubleshooting WLAN IP Telephony installations
Multiple times is better—copy and paste the following commands on the
WLAN Security Switch 2270 CLI, rather than typing them individually. The
screen begins scrolling with output as soon as you type the commands.
• show run-config (from all WLAN Security Switch 2270s)
• show tech support
• show msglog
The wired sniffer must sniff the Gig port of the WLAN Security Switch
2270. No capture filter is required; get everything.
Obtain the wireless capture from the channel that the handsets currently
use. Configure the wireless sniffer to capture from only one channel. To
determine which channel, first show the client summary. Look for the
MAC of the client showing status associated and note the name of the AP
beside it. To see the channel that the AP operates on, show the advanced
802.11b summary.
Follow the steps in Procedure 29 “Obtaining the wired and wireless
captures” (page 210), to capture data to send to Nortel for analysis.
