LMS 4.x - is neccessary to run cdp or lldp for discrepancy reports?

[ROMAN TOMASEK]

Hi,

I have one question about discrepancy detection. How LMS provides the detection of discrepancy? For example when the ports have discrepancy about the duplex mismatch. Is it detected by CDP or LLDP or the some monitoring of discard statistics on interfaces is provided? Is neccesary to run CDP or LLDP between devices for looking for discrepancies?

Thank you

I have read on this forum I think in one of Joe posts that lms queries other mibs then CDP LLDP tables to obtain the duplex and speed settings.

However if these protocols are not running I'm not sure if the ports will be seen as linked ports.

Cheers,

Hello Michel,

thank you. So it is recommended to use cdp or lldp for the correct function of discrepancy reports, isn't it? Without cdp (lldp) the problem with the discovery of linked ports can occur, can't it?

Just CDP. I have not yet seen a link getting discovered via LLDP.

I think it needs CDP running to discover the links between the devices.

It will then check the discrepancies because it understands the ports are part of a link.

Cheers,
