? InCellErrors – increments when a T3 or an E3 ATM interface receives cells for a VPI or VCI that
is not configured on that interface
? This command also displays information specific to the applicable physical interface. In the
example below, the output contains the following physical interface fields:
? SONET path operational status – state of the SONET path interface: up, down, lowerLayerDown ? time since last status change – time since last reported change to the SONET path operational
status
? SONET operational status – state of SONET interface: up, down, lowerLayerDown
? time since last status change – time since last reported change to the SONET operational status ? PHY Type – module on which this interface is running ? Framing – framing type of the physical interface
? TX clocking – clocking type for the physical interface
? Loopback – loopback status for the physical interface: enabled, disabled ? Receive FIFO Overruns – number of times received FIFO was overrun ? Configured Interface – slot and port number of the ATM interface ? Status – status of the ATM interface: up, down, lowerLayerDown ? Configured VCs – number of VCs configured on the interface

3.2.1.4 show atm subinterface

? Interface – subinterface number ? ATM-Prot – ATM protocol type ? VCD – virtual circuit descriptor ? VPI – virtual path identifier ? VCI – virtual channel identifier
? Type – circuit type (PVC is the only type supported for the current system version.)
? Encap – administered encapsulation method based on what was configured via the atm pvc
command
? MTU – MTU size for the interface
? Status – state of the subinterface: Up, Down, Dormant, LowerLayerDown, Absent
? Auto configure status – setting of the autoconfigure feature. Dynamic means that the feature is on
and the next upper interface will be automatically detected. Static
means that the feature is off.
? Auto configure upper interface(s) – type of dynamic upper interface(s) configured using the auto-configure command: IP, PPP, PPPoE, bridged Ethernet
? Detected 1483 encapsulation – if the encapsulation type is set to aal5autoconfig, displays the
1483 encapsulation type detected on the subinterface (displays AAL5-AUTO until a packet is detected)
? Detected dynamic upper interface – type of dynamic upper interface detected during
autoconfiguration
? Assigned profile – for each dynamic interface type, shows whether or not a profile is assigned and,
if assigned, shows the profile name
? SNMP trap link-status – whether the trap link status is enabled or disabled ? InPackets – number of packets received on this interface ? InBytes – number of bytes received on this interface
? OutPackets – number of packets transmitted on this interface ? OutBytes – number of bytes transmitted on this interface ? InErrors – number of errors received on this interface ? OutErrors – number of outgoing errors on this interface
? InPacketDiscards – number of incoming packets discarded on this interface ? OutDiscards – number of outgoing packets discarded on this interface ? Example 1 – displays the current state of all ATM subinterfaces
