Hello,
I work for a school district and we connect an off campus building via 2 - Alvarion B100 5.4 or 5.8 Ghz radios. Sorry I'm waiting for an answer from our vendor re: which they are. We run VOIP and Data over this connection. The VOIP quality stays fine, but access to servers and Apps become Dog slow after a while. We reset the radios and ping times are at 1 ms which is great. As time progresses, ping times skyrocket into the 100 and 200+ range. We think it must be interference somehow. I can't remember. Below are configs for the ports each side connect to.
4506 Core Switch config
interface FastEthernet3/46
description to Bridge for District
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,107,117,451,710,740,760
switchport mode trunk
duplex half
qos trust dscp
tx-queue 1
shape 10000000 bps
tx-queue 2
shape 10000000 bps
tx-queue 3
priority high
shape 20000000 bps
tx-queue 4
shape 10000000 bps
Layer 2 - Cat 3506 switch on the other end:
interface FastEthernet0/24
description to Bridge
switchport trunk encapsulation dot1q
switchport mode trunk
speed 100
duplex half
srr-queue bandwidth limit 50
priority-queue out
mls qos trust dscp
end
Any suggestions on monitoring this, or being able to read interference in the AIR would be great. The GUI for the radios seems to show no interference on the channels. Our vendor has changed to different channels, etc...to try new things. Currently they are using the 5800 MHz frequency and subband 2 40 MHz with a transmit power of 21. Can someone point me in the right direction who to ask, or where to look?
Any help is greatly appreciated.
Thanks, Dan Christ
