hcxStuAltDownFreq

Module: COM21-HCXTOP-MIB

OID (symbolic): COM21-HCXTOP-MIB::hcxStuAltDownFreq

OID (numeric): 1.3.6.1.4.1.1141.2.5.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute defines an alternate ComController downstream frequency. This attribute would be utilized if an unrecognized ComPort is acquired and the hcxStuAltDownFreqEnable is set to enable. Minimum step size is 200. i.e. 200000hz. Default is 0, indicating no alternate frequency.

What is hcxStuAltDownFreq?

This read-write integer (88000-800000, step 200, meaning multiples of 200 kHz) sets an alternate downstream frequency the ComController falls back to when an unrecognized ComPort is acquired and hcxStuAltDownFreqEnable is set to enable. A default of 0 means no alternate frequency is configured, so an admin who wants unrecognized modems steered off the primary channel must set a real value here. For example, an admin sets this to 350000 (350 MHz) so a newly discovered legacy modem is redirected there instead of camping on the main service frequency.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.5.9
snmpwalk -v2c -c public <target> COM21-HCXTOP-MIB::hcxStuAltDownFreq

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.5.9.1
snmpget -v2c -c public <target> COM21-HCXTOP-MIB::hcxStuAltDownFreq.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1141.2.5.9.1 i <value>
