What is hcxUpstreamShelfId?
This read-only INTEGER (1..2) identifies which of the two physical shelves in the headend chassis houses the upstream RX card being reported on. It lets management software address a specific upstream unit's location in a multi-shelf HCX system rather than assuming there is only one shelf. For example, when a fault report comes in for slot 4, the admin also checks hcxUpstreamShelfId to know whether to walk to shelf 1 or shelf 2 to physically inspect the card.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.33.1.1.1 snmpwalk -v2c -c public <target> COM21-HCXRX-MIB::hcxUpstreamShelfId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.33.1.1.1.1 snmpget -v2c -c public <target> COM21-HCXRX-MIB::hcxUpstreamShelfId.1
