I am using several DWL-2100 radios in various
kind of configurations. Several of them have problems that I relate to MAC
address table learning and aging. I am interested to learn if any one else has
similar problems and/or knows more about this.
Software version is either 1.01eu or
2.0eu
In one configuration I have a two routers (A and
B) that are linked together with one DWL-2100 P2P bridge, a LAN segment and
then a Roamabout P2P link.Users on the LAN segment has their default gateway
set to router A. On another subnet connected to router B there is a monitoring
system that send ping probes to users on the LAN segment and to the
radios.
Parallel (on same subnet) to the monitoring
system there is a mailserver that users on the LAN segment are supposed to
access.
If there is no, or little, traffic over the
DWL-2100 link, the MAC address tables seems to time out so that users on the
LAN segment can not access the mailserver. If I let some other system
constantly (within MAC address table aging parameter, send ping packets to the
user's PC the problem goes away, and users are able to access the mailserver
without problems.
Another configuration involves a monitoring
system connected to a router to subnet C. Another WAP54 P2P link connect
another site that has a DWL-2100 P2MP link. On one of the MP legs there is
another P2P DWL-2100 link that links in a third location.
When the monitoring system tries to ping the last
P2P link it will not get proper responses. Of 10 packets I may recieve 2. But
if I let another system, connected to the same subnet as the P2Plink ping the
radio, then the monitoring system get 10 out of 10 ping packets
