This  causes Network Management Systems such as 3Com Router Manager and 3Com Network  Director to generate errors. To resolve this, exit the System View.  • The Frame Relay MIB does not use the latest version of the RFC 2115. As a resul

It is best to observe the interface’s Current State. The Current State will be  down if no cable is attached to the interface even though the Line Protocol will show it as  up.  • A Frame Relay sub-interface that has been configured as “Down” transmits packets.  • Displaying a Fractional E1 interface displays a Fram

DTMF digits sent from router  5000/6000 to VCX phones will be disregarded.  • Removal of the Master SIP server from a voice configuration will remove the following from  the configuration:  o Slave SIP server if one exists  o “address sip proxy” for SIP VoIP entities  • Voice is barely audible when an NBX T1 is attached to the router configured running QSIG  master (net

Therefore, if a voice entity using one of these interfaces is routing calls, and the  interface goes down, the router will not check for a voice entity with equivalent match  criteria to use. The router will continue to attempt to send calls through the down interface.  • CLI doesn’t support pre-defined ringing tones for the following
