hwVfbTransmitGain
Module: HUAWEI-VFB-MIB
OID (symbolic): HUAWEI-VFB-MIB::hwVfbTransmitGain
OID (numeric): 1.3.6.1.4.1.2011.6.23.1.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: port transmit gain select, two userline mode range(10-15), four userline mode range(1-16) 1:+14dB, 2:+13dB, 3:+12dB, 4:+11dB, 5:+10dB, 6:+9dB, 7:+8dB, 8:+7dB, 9:+6dB, 10:+5dB, 11:+4dB, 12:+3dB, 13:+2dB, 14:+1dB, 15:0dB, 16:-1dB
What is hwVfbTransmitGain?
This read-write INTEGER (1-16) selects the transmit gain applied to a VFB port, where each step maps to a defined dB adjustment from +14dB at value 1 down to -1dB at value 16. Admins tune this to control outgoing voice-frequency signal strength so it matches the loop length and avoids overdriving or underdriving the line. For example, lowering the value from the default of 10 (+5dB) to 15 (0dB) reduces transmit level on a short, low-loss subscriber loop.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.6.23.1.1.1.3 snmpwalk -v2c -c public <target> HUAWEI-VFB-MIB::hwVfbTransmitGain
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.6.23.1.1.1.3.1 snmpget -v2c -c public <target> HUAWEI-VFB-MIB::hwVfbTransmitGain.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2011.6.23.1.1.1.3.1 i <value>
