Re: Please help to clarify some things!


Again, you are confusing the issues.  Out of band network management can use IP
as the transport protocol.  TL1 over TCP/IP is commonly used.  What is not used
is element and network management based on SNMP in band with the customer data
for transmission network elements.  IS-IS is also used as the transport protocol
for transmission network element and network management.  The element management
protocol for IS-IS is CMISE/Q3.

Thank you,
