MLI

simple question

Does MLI work as a troubleshooting utility for both - PVC and SVC?

Thanks

MLI = Local Menagement Interface
VPC = Permanent Virtual Circuit
SVC = Switched Virtual Circuit

this is all in relation to Frame-Relay (WAN encapsulations/protocols)

any ideas?

LMI not MLI, and PVC not VPC!

LMI offers Status messages and multicasting across Frame links.

The LMI global addressing extension gives Frame Relay data-link connection identifier (DLCI) values global rather than local significance

LMI virtual circuit status messages provide communication and synchronization between Frame Relay DTE and DCE devices, they send periodic reports to prevent "black holes"

sorry for the missleading definition, i get tired at work

ok so does LMI serve both PVC and SVC?

Thanks

With regards to SVC, LMI provides the mapping, however PVC is more common and the "de facto" for frame networks. Have a read of the link I posted it gives a good explanation.
