wfDiffServDsByteMask

Module: Wellfleet-DIFFSERV-MIB

OID (symbolic): Wellfleet-DIFFSERV-MIB::wfDiffServDsByteMask

OID (numeric): 1.3.6.1.4.1.18.3.5.26.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Bitmask which is AND'ed with DS-byte stting and then OR'ed with DS-byte in the packet. It masks out bits.

What is wfDiffServDsByteMask?

This read-write value is a bitmask that gets AND'ed with the configured DS-byte setting and then OR'ed into the DS byte of outgoing packets, effectively masking out selected bits of the DiffServ code point before it's applied. Admins use it to control which bits of the DS byte are actually allowed to be modified versus preserved from the original packet. An admin wanting to only ever set the top three DSCP bits while leaving the rest untouched would craft this mask accordingly.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.26.1.3
snmpwalk -v2c -c public <target> Wellfleet-DIFFSERV-MIB::wfDiffServDsByteMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.26.1.3.1
snmpget -v2c -c public <target> Wellfleet-DIFFSERV-MIB::wfDiffServDsByteMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.26.1.3.1 i <value>
