1410 x 4
sector antenna x 4
three sites.... two root bridges on tope of hq, and two non-root bridges one for each remote sites
root1 -> remote site 1 (3km)
root2 -> remote site 2 (1.5km)
the above mentioned setup is working fine.
to save one ap+antennax2, replaced one sector with an omni.
so, now...
1410 x 3
omni x 1 (headquarters) part# AIR-ANT58G9VOA-N
sector x 2 (remote sites)
root1 -> remote site 1 (3km)
root1 -> remote site 2 (1.5)
upon replacing the root bridge antenna from sector to omni, the following occured:
1. lost connection between root bridge and the switch.
2. show cdp on switch will not show the bridge.
3. show cdp on bridge will not show the switch.
4. switchport status is up and led is lit normal.
5. connecting to the root bridge... connection to the remote bridge is ok, remote bridge is associated and pingable. but after a while connection will be lost.
6. a bridge power reset will restore the connection but the problem will come again after some time. with power reset i'm unable to see the logs.
7. some times an hour, and sometimes after 10 - 12 hours before the problem occurrs again.
8. installed the omni antenna upward, on top of pole... same problem.
9. installed the omni downward (close to pole)... same probem.
10. installed the omni downward (away from pole with 0.5m metal arm)... same problem.
11. replaced the power injector... same problem.
12. replaced the patch cord from root bridge to switch.... this lasted for more than 12 hours and the problem came back.
13. switch show log only show that there has been a switchport reset on the port where the root bridge is connected.
14.
what coudl be the problem here.
thanks, experts!
