What is nwAppnExtIfDfltMaxSBtuSize?

This read-write integer (99-65535) sets the default maximum Message Unit size that can be sent on this port. It complements nwAppnExtIfMaxRBtuSize by controlling the send side rather than the receive side of MU sizing for this port. An admin matching this router's send capability to a remote device's stated receive limit would size this accordingly.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.16
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfDfltMaxSBtuSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.16.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfDfltMaxSBtuSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.16.1 i <value>
