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):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.31.1.1.11.1
snmpget -v2c -c public <target> COM21-HCXRX-MIB::hcxUpstrmAltFreqB.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
