Module: FRX-MIB

OID (symbolic): FRX-MIB::portInterfaceProtocol

OID (numeric): 1.3.6.1.4.1.177.3.3.1.1.3

Description: Determines the function of the port, including which UNI protocol is to be used. All values except interNode are for ports at access points into the network. InterNode is for ports internal to the network. AnsiNetwork, ansiUser, and ansiNNI conform to procedures specified in the ANSI T1.617 Annex D specification. ccittNetwork, ccittUser, and ccittNNI conform to procedures specified in the CCITT Q.933 Annex A specification. lmiNetwork, lmiUser, and lmiNNI conform to procedures specified in the DEC, Northern Telecom, StratCom specification.

What is portInterfaceProtocol?

Selects which UNI/NNI signaling protocol variant this port runs -- ANSI T1.617 Annex D, CCITT Q.933 Annex A, or LMI (DEC/Northern Telecom/StratCom) -- in Network, User, or NNI role, or marks the port as an internal inter-node trunk; an admin sets this to match whatever protocol the far-end CPE or carrier switch expects.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.177.3.3.1.1.3
snmpwalk -v2c -c public <target> FRX-MIB::portInterfaceProtocol

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.177.3.3.1.1.3.1
snmpget -v2c -c public <target> FRX-MIB::portInterfaceProtocol.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.177.3.3.1.1.3.1 i <value>
