MLM is very lightweight and can run on the same system as netview. So no
additional hardware required.

Thanks for replying Denis,
Unfortunately MLM is not an option at this point. Was hoping for a solution
on existing system that does not require hardware upgrades/additions.
Cheers,

Hi,
You can use a MLM to filter the events before they reach your Netview and
you can also easily use the MLM to define snmp collection rules and to
trigger traps when the threshold you have defined are breached. MLM was the
answer for me to a couple of tricky situations, especially to filter traps
coming from source where you can't control them.
Check the MLM user guide, it will give you more insight on what you can do
with MLM
Hope that helps

[NV-L] Advice on
Monitoring Wireless
Access Points
Dear List,
Looking for advice on how others are managing these devices on Netview.
We've recently installed 500 Cisco Aironet 1231 Access Points and have run
into a few problems. Traps are being sent to a WLSE which in turn forwards
traps to Netview. We receive 10 traps per second just to let us know an AP
is running OK. If there's a problem, eg. snmp unreachable, we receive 120
traps per sec. (not good). These traps are taking up over 70% of the
trapd.log (also not good).
>From reading the archives, it appears the WLSE modifies the trap before
sending to Netview and a fair bit of work is required to parse these traps
into a more meaningful trap to alert the Operators. We're also receiving
all AP traps from the WLSE but we really only want to see link up/down and
also problems on the radio side of the link. Not sure if the WLSE can be
configured to only send these specific traps to Netview (another area looks
after the WLSE).
Another option is for the APs to send traps directly to Netview but again
we would get flooded with traps we don't want to see. I guess they could be
filtered from appearing in the trapd.log but this may mask performance
issues caused by the high volume of traps.
Also on the archives, there was mention of collecting SNMP data from the AP
mibs (and using snmpColDump) for monitoring the radio side of the APs. Is
this the only way (or the best way) to monitor if a radio goes down? This
option sounds interesting but would require a fair bit of work in managing
and processing the collected data. This would require the APS to be on the
Netview maps (they aren't at present since they are DHCP - the ip addresses
are only static for as long as the AP is active) so we'd have some ongoing
management issues unless we convince the designers to change them to static
ip addresses.
If we turn off receiving any traps from the WLSE we can still monitor link
up/down on the APS as the switch they are connected to sends trps when a
port goes down. However, we'd also like to see when a radio goes down.
How is everyone else handling this? Thanks in advance for any advice..
By the way, we're running 7.1.3 FP3 on unix.
Best Regards,
Sue Young
