Show interfaces Command Example FTOS#show interfaces fortyGigE 0/0 fortyGigE 0/0 is down, line protocol is down Hardware is DellForce10Eth, address is 90:b1:1c:f4:99:ce Current address is 90:b1:1c:f4:99:ce Pluggable media present, QSFP type is 40GBASE-SR4 Wavelength is 850nm QSFP receive power reading is -2.4397dBm Interface index is 33702145 Rx power is displays in dBm units. Power via SNMP: Rx power: OID Name: chSysPortXfpRecvPower SNMP OID: .1.3.6.1.4.1.6027.3.10.1.2.5.1.6 1. SNMP walk to this object identifier (OID) to obtain the Rx power of the connected optics. 2. The measured power is in the unit's dbm. Measured Rx power is converted to dbm using following calculation, This value is then multiplied by 100 and displayed in SNMP.(Figure 13-10) Power in dbm = 10*log (measured Rx power) Figure 13-10. Rx Power Calculation Example Rx Power = 0.006mW Then Power = 10 * log (0.572mW) dBm = -2.42 dBm The value displayed in Snmp = -242 Tx Power: OID Name: chSysPortXfpTxPower Snmp OID: . 1.3.6.1.4.1.6027.3.10.1.2.5.1.8 1) SNMP walk to this OID to obtain the Tx power of the connected optics. 2) The measured power is in the unit's dbm. 246 | Debugging and Diagnostics
