zyNdpPrefixValidLifetime
Module: ZYXEL-IPV6-NDP-MIB
OID (symbolic): ZYXEL-IPV6-NDP-MIB::zyNdpPrefixValidLifetime
OID (numeric): 1.3.6.1.4.1.890.1.15.3.35.1.3.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Enter the number of Valid Lifetime for the interface. Range of Valid lifetime is (0 to 4294967295). The default value is 2592000.
What is zyNdpPrefixValidLifetime?
Sets the valid lifetime, in seconds, advertised for this IPv6 prefix, i.e. how long hosts should consider addresses derived from it usable at all, in a range of 0 to 4294967295 per the object's description. Admins configure this in router advertisements so downstream hosts know when to stop using and eventually remove addresses formed from this prefix, supporting IPv6 address renumbering. The default of 2592000 seconds, or 30 days, means hosts will keep an address based on this prefix valid for a month; an admin renumbering sooner might lower zyNdpPrefixValidLifetime to force faster address turnover.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.35.1.3.1.5 snmpwalk -v2c -c public <target> ZYXEL-IPV6-NDP-MIB::zyNdpPrefixValidLifetime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.35.1.3.1.5.1 snmpget -v2c -c public <target> ZYXEL-IPV6-NDP-MIB::zyNdpPrefixValidLifetime.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.890.1.15.3.35.1.3.1.5.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> zyNdpPrefixValidLifetime.1
