provides probable causes and possible solutions.
Table24-12 Troubleshooting Problems
Problem
Probable Cause
Possible Solution
An end host
cannot be
discovered.
ILMI is not enabled.
Enable ILMI on the affected end host.
No SNMP connection to
the end host exists.
Set up the SNMP connection to the end
host. Make sure that all device
requirements are met.
The LEC does not
appear in ELAN
map.
Device where LEC
resides is not SNMP
reachable, or it was
incapable of joining the
ELAN.
Check to see if the LEC exists in the
ELAN, and check to see if the device
is SNMP reachable.
The LEC cannot
join an ELAN.
The LEC was not
discovered as a valid
LEC.
Check to see if the device where the
LEC resides is SNMP-reachable.
The LEC was discovered
at one time, but it went
down and could not
rejoin the ELAN.
Check the status of the LEC; make
sure its address is configured correctly
on the LightStream 1010.
Check the last failure state of the LEC.
No connectivity
exists between
clients.
Clients belong to
different ELANs.
Verify that both clients belong to the
same ELAN.
One client is unknown to
the other.
Check the client ARP information to
see if it is known to the LE client.
Client(s) are not
registered with the LES.
Check the LES status parameters
window.
The BUS
performance
graph indicates
high usage.
A client is using the
maximum amount of
bandwidth.
Determine which LEC is generating
heavy broadcast usage. Check the
TopN clients.
