Description: The value of GRE key
What is hh3cGreKeyValue?
This holds the numeric key value used in the GRE tunnel's key field, a shared identifier both tunnel endpoints must match for the tunnel to accept traffic. An admin configures this to add a layer of tunnel validation -- GRE key mismatches cause the receiving router to drop packets, helping prevent misdirected or spoofed GRE traffic from being accepted. Setting this to 12345 on both ends of a GRE tunnel ensures each router only accepts GRE packets carrying that matching key value.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.25506.2.54.1.1.1.1 snmpwalk -v2c -c public <target> HH3C-GRE-MIB::hh3cGreKeyValue
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.25506.2.54.1.1.1.1.1 snmpget -v2c -c public <target> HH3C-GRE-MIB::hh3cGreKeyValue.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.25506.2.54.1.1.1.1.1 i <value>
