cnt2XIfSpeed

Module: CNT21-MIB

OID (symbolic): CNT21-MIB::cnt2XIfSpeed

OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.8

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: An estimate of the interface's current bandwidth in bits per second. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth.

What is cnt2XIfSpeed?

This Unsigned32 gives the extended-table's estimate of the interface's current bandwidth in bits per second, falling back to nominal bandwidth when a live estimate isn't possible. An administrator monitors it the same way as the base table's speed field, watching for an interface running below its rated capacity. For example, cnt2XIfSpeed reporting only 100000000 on a card expected to run at gigabit rates signals an autonegotiation problem on that extended-table row.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.2.1.2.3.1.8
snmpwalk -v2c -c public <target> CNT21-MIB::cnt2XIfSpeed

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.333.2.1.2.3.1.8.1
snmpget -v2c -c public <target> CNT21-MIB::cnt2XIfSpeed.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cnt2XIfSpeed.1
