Description: Fragment size used by GRE to fragment data pkts
What is usrVHAGreFragmentSize?
It sets the fragment size, in bytes (64-64000), that GRE uses when fragmenting outgoing data packets, defaulting to 1450. An admin would lower this if a path along the RP tunnel has a smaller MTU than the default assumes, to avoid black-holed oversized packets.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.429.4.84.1.18 snmpwalk -v2c -c public <target> USR-VHA-MIB::usrVHAGreFragmentSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.429.4.84.1.18.1 snmpget -v2c -c public <target> USR-VHA-MIB::usrVHAGreFragmentSize.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.429.4.84.1.18.1 i <value>
