ifSpecific
Module: CHECKPOINT-MIB-2
OID (symbolic): CHECKPOINT-MIB-2::ifSpecific
OID (numeric): 1.3.6.1.2.1.2.2.1.22
Node type: OBJECT-TYPE
Type: OBJECT IDENTIFIER
Access: read-only
Description: A reference to MIB definitions specific to the particular media being used to realize the interface. For example, if the interface is realized by an ethernet, then the value of this object refers to a document defining objects specific to ethernet. If this information is not present, its value should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntatically valid object identifier, and any conformant implementation of ASN.1 and BER must be able to generate and recognize this value.
What is ifSpecific?
An OID pointer to the media-specific MIB table that has additional detail for this particular interface type, such as Ethernet-specific objects. This is mainly useful to a generic SNMP browser or NMS that needs to know where to look for media-specific counters, like Ethernet collision statistics, beyond the generic ifTable fields, rather than something an admin reads directly as a value. Example: ifSpecific pointing into the Ethernet-like MIB tells a polling tool to also fetch collision and alignment-error detail for that interface from the referenced table.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.2.2.1.22 snmpwalk -v2c -c public <target> CHECKPOINT-MIB-2::ifSpecific
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.2.2.1.22.1 snmpget -v2c -c public <target> CHECKPOINT-MIB-2::ifSpecific.1
