ifExtnsChipSet

Module: RFC1229-MIB

OID (symbolic): RFC1229-MIB::ifExtnsChipSet

OID (numeric): 1.3.6.1.2.1.12.1.1.2

Node type: OBJECT-TYPE

Type: OBJECT IDENTIFIER

Access: read-only

Description: This object identifies the hardware chip set being used in the interface. The assignment of OBJECT IDENTIFIERs to various types of hardware chip sets is managed by the IANA. If the hardware chip set is unknown, the object identifier

unknownChipSet OBJECT IDENTIFIER ::= { 0 0 }

is returned. Note that unknownChipSet is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value.

What is ifExtnsChipSet?

This object identifier names the hardware chip set that implements the interface, drawn from an IANA-maintained registry of chip-set OIDs. An admin can use it to determine exactly which silicon drives a given NIC, which matters when chasing chip-specific bugs or checking firmware advisories. If the agent cannot determine the chip set, it returns the reserved value unknownChipSet ({0 0}) rather than leaving the object empty.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.12.1.1.2
snmpwalk -v2c -c public <target> RFC1229-MIB::ifExtnsChipSet

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.12.1.1.2.1
snmpget -v2c -c public <target> RFC1229-MIB::ifExtnsChipSet.1
