Phase 4: Problems with Normal ATM Operation
The problems in this phase occur after ATM traffic is started in the network between
ATM devices attached to ATM media ports. The ATM port status is OKAY.
Important: Problems in the normal operation of your ATM subnetwork may occur
when the maximum number of virtual connections (VCs) allowed on a ONcore hub or
an individual ATM media module is exceeded. The maximum number of virtual
connections supported is as follows:
3000 per ONcore hub
992 per ATM media module (with up to 992 VCs per ATM media port).
The aim of the troubleshooting operations in Phase 4 is to restore normal operation to
the network so that ATM traffic can continue.
If you cannot solve the problem after performing the troubleshooting operations
described in this section, contact your 3Com service representative.
