Module: HUAWEI-TUNNEL-MIB
OID (symbolic): HUAWEI-TUNNEL-MIB::hwIpv6TunnelHopLimit
OID (numeric): 1.3.6.1.4.1.2011.5.25.201.1.2.1.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object specifies Tunnel ipv4-ipv6 hop limit.
What is hwIpv6TunnelHopLimit?
This object specifies the hop limit, equivalent to IPv4's TTL, placed in the outer header of ipv4-in-ipv6 tunneled packets. Admins adjust this to control how many router hops the encapsulated tunnel packet can traverse before being discarded, guarding against routing loops consuming resources indefinitely. With the default value of 64, tunneled packets are dropped if they haven't reached their destination after 64 hops, matching typical IP TTL defaults.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.201.1.2.1.4 snmpwalk -v2c -c public <target> HUAWEI-TUNNEL-MIB::hwIpv6TunnelHopLimit
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.201.1.2.1.4.1 snmpget -v2c -c public <target> HUAWEI-TUNNEL-MIB::hwIpv6TunnelHopLimit.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.2011.5.25.201.1.2.1.4.1 i <value>
