I've got a few Cisco 7925G's that we're demo'ing out. So far they've been working extremely well, we've been very impressed. (I did a 6 hour conference call on one)
We've been having a few problems with them loosing audio for a few seconds here and there. I finally was in the WLC interface when it happend, and I captured this out of the trap log: (I've removed some extraneous messages) 2 Fri Jun 11 11:36:57 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c4:60 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 3 Fri Jun 11 11:36:51 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:9c:af:ca:0f:71:10 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 15 Fri Jun 11 11:36:40 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c4:60 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 17 Fri Jun 11 11:36:35 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:9c:af:ca:0f:71:10 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 19 Fri Jun 11 11:36:25 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c4:60 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 21 Fri Jun 11 11:36:19 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:9c:af:ca:0f:71:10 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 24 Fri Jun 11 11:36:01 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c4:60 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 25 Fri Jun 11 11:35:55 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:9c:af:ca:0f:71:10 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 29 Fri Jun 11 11:35:44 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c4:60 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 30 Fri Jun 11 11:35:39 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:9c:af:ca:0f:71:10 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 31 Fri Jun 11 11:35:28 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c4:60 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 34 Fri Jun 11 11:35:23 2010 Client Authenticated: MAC Address:00:26:99:46:c2:e2 base Radio MAC:64:16:8d:ef:c3:10 Slot: 1 User Name:phone03 IP Addr:10.1.43.126 SSID:CMW01 So obviously, it's bouncing between AP's, and doing it fast. It's my normal Customer WLAN, using AAA override to bump the priority up to Platinum level. It's using WPA2/AES Enterprise. The SNR of my client, to AP 64:16:8d:ef:c4:60 is 45, on the 802.11a band. WMM is enabled. Got any idea's on where I should look? Agressive Load Balancing is OFF (per Cisco Docs) On the WLAN AAA Overide is enabled Aironet IE is enabled Client Load Balancing is enabled Client Band Select is enabled My thought is the Client Load Balancing the suspect. But I can't find good documentation on what it is, and what it does, and whether it should be turned off.
