hcxUpstrmAltFreqB
Module: COM21-HCXRX-MIB
OID (symbolic): COM21-HCXRX-MIB::hcxUpstrmAltFreqB
OID (numeric): 1.3.6.1.4.1.1141.2.31.1.1.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Contains the second alternate frequency for this RX port. Same restrictions and defaults as for hcxUpstrmAltFreqA.
What is hcxUpstrmAltFreqB?
This read-write INTEGER (0..40000) configures the second alternate hop frequency for the RX port, following the same rules and defaults as hcxUpstrmAltFreqA per the description. It gives the port a second fallback option beyond the first alternate, useful when a single alternate frequency is not reliably clean either. For example, an admin populates hcxUpstrmAltFreqB with a different clean frequency band so the port has two distinct escape routes if noise affects one of them.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.31.1.1.11 snmpwalk -v2c -c public <target> COM21-HCXRX-MIB::hcxUpstrmAltFreqB
Get a specific instance (index 1):

Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1141.2.31.1.1.11.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> hcxUpstrmAltFreqB.1
