The PW-ATM-MIB does not support cell counters on the Cisco 7500 series router. Consequently, an 
SNMP query for cell counters returns a 0 value.
The PW-ATM-MIB does not support a high-capacity cell counter per virtual path (VP) or cells per 
port.
The PW-ATM-MIB virtual path identifier (VPI)/virtual channel identifier (VCI) value for port mode 
cell relay is 0.
The PW-ATM-MIB VP cell relay VCI value is 0.
The PW-ATM-MIB VP does not support ATM adaptation layer 5 (AAL5); therefore, all packet 
counters are invalid.
Note
This feature is not supported over Ethernet, Frame Relay, and ATM in all releases. See the 
 for more detailed information.
