nwAppnFwdIfMtu

Module: CTRON-APPN-MIB

OID (symbolic): CTRON-APPN-MIB::nwAppnFwdIfMtu

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.1.1.6

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object does not apply to this protocol. It is a common object, inherited from the MIB framework used to provide a common management interface to all the Cabletron Routing Services protocol-specific MIBs. Setting this object has no effect.

What is nwAppnFwdIfMtu?

This read-write integer object exists only as a common placeholder inherited from the shared Cabletron Routing Services MIB framework and setting it has no effect on APPN port behavior. An admin should look to APPN-specific size objects such as nwAppnExtIfMaxRBtuSize or nwAppnExtIfDfltMaxSBtuSize instead of this OID for actual MTU-like controls. Writing a value here will not change the maximum frame size the APPN port actually uses.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.1.1.6
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdIfMtu

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.1.1.6.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnFwdIfMtu.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.1.1.6.1 i <value>

SNMPv3 example:

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