What is applePortChecksum?

This enables or disables generation of checksums on outgoing DDP (Datagram Delivery Protocol) packets for this AppleTalk port, defaulting to disabled. An admin would enable it when the far end validates DDP checksums and unexplained AppleTalk packet drops suggest corruption is going undetected.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.21.2.1.1.5
snmpwalk -v2c -c public <target> ITOUCH-APPLETALK-MIB::applePortChecksum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.33.21.2.1.1.5.1
snmpget -v2c -c public <target> ITOUCH-APPLETALK-MIB::applePortChecksum.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.33.21.2.1.1.5.1 i <value>
