Module: BAYSTACK-IPV6-FIRST-HOP-SEC-MIB

OID (symbolic): BAYSTACK-IPV6-FIRST-HOP-SEC-MIB::bsIpv6FHSDhcpv6gPrefLimitMax

Description: This is check against the DHCPv6 server / relay router preference. If the received router preference is greater than the configured router preference than drop the packet

What is bsIpv6FHSDhcpv6gPrefLimitMax?

Sets the maximum acceptable router preference value for DHCPv6 server or relay messages; any message whose router preference exceeds this threshold is dropped by the DHCPv6 guard policy. This prevents unusually high-preference rogue DHCPv6 servers from hijacking address assignment.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.45.1.5.1.6
snmpwalk -v2c -c public <target> BAYSTACK-IPV6-FIRST-HOP-SEC-MIB::bsIpv6FHSDhcpv6gPrefLimitMax

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.45.1.5.1.6.1
snmpget -v2c -c public <target> BAYSTACK-IPV6-FIRST-HOP-SEC-MIB::bsIpv6FHSDhcpv6gPrefLimitMax.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.45.1.5.1.6.1 i <value>
