Symptom
Problem
Resolution
All base stations are
synchronization masters
Multicast traffic is blocked in
the network.
Enable multicast traffic on all switches between
the base stations.
Synchronization is OK at
startup but fails after a
short period
IGMP snooping is active, but
no IGMP querier is present on
the network to refresh multicast
group memberships.
Add an IGMP querier to the network or disable
IGMP snooping.
Base stations do not
synchronize or loose
synchronization often.
The traffic between base
stations is being delayed a
varying amount of time due to
traffic load, switch quality or
configuration.
Reconfigure/replace switches or change the
network topology to minimize the transmission
time variance.
