Handling Process
A:
More explanation can be seen in the attachment.
[MA5200G] display interface ATM 2/0/0 verbose
Atm2/0/0 current state: up //If physical port state is down, it indicates link transceiver is problematic and it is not related with configuration.
Line protocol current state: down //If link protocol state is down, configuration parameter is false and two ports cannot negotiate.
Physical layer is ATM STM-1, //It means STM-1 link and the rate of STM-X link is 155M*x. For example, STM-4 means 622M and STM-16 2.5G.
Compliance: OC3-LC-SM //It means card information. SM means single mode (MM multimode) and LC means LC interface.
VendorName: AGILENT // vendor information of optical interface mode.
PartNumber: HFCT-5760T //vendor type of optical interface mode .
Mode: SingleMode //The specification of optical interface mode .
is single mode.
WaveLength: 1310 //Wave length of optical interface is 1,310nm.
Length for 9/125um: 15,000m // transmission example 15,000 m
Description: HUAWEI, Quidway Series, Atm2/0/0 Interface
The Maximum Transmit Unit is 1500 bytes, the BandWidth is 155000 Kbits //The maximum transmission MTU and link bandwidth.
Encapsulation type ATM, loopback not set, clock source internal //Link encapsulated format and not set loop (Normal work link cannot be configured as loop and loop is used for checking link), clock is internal clock.

Encapsulation(s): AAL5, PVC mode // ATM encapsulated mode AAL5, PVC connection.
UBR: 1443, CBR: 0, VBR: 0
USED BandWidth: 0Kbps
Statistics last cleared: never //Port clears data statistics time the last time.
Traffic statistics: //Instant rate statistics of the port.
