DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Command Mode Interface Configuration Mode. Usage Guideline For a prefix, the valid lifetime should be greater than the preferred lifetime. They are meaningful when the prefix has the A bit ON. The received host will do a stateless address configuration based on the prefix. If the lifetime of the prefix has exceeded the preferred lifetime, then the IPv6 address configured based on this prefix will change to the deprecated state. If the lifetime of a prefix has exceeded the valid lifetime, then the IPv6 address configured based on this prefix will be removed. If the IPv6 address is manually configured on the interface, the corresponding prefix will automatically be advertised. The advertised prefix can be modified but cannot be removed using this command. If the IPv6 address is removed later, the advertising of the corresponding prefix will also be stopped. Example This example shows how to configure an IPv6 prefix 3ffe:501:ffff:100::/64 with a valid lifetime of 30000 seconds and a preferred lifetime of 20000 seconds. Switch# configure terminal Switch(config)# interface vlan1 Switch(config-if)# ipv6 nd prefix 3ffe:501:ffff:100::/64 30000 20000 Switch(config-if)# 10-10 ipv6 nd ra interval This command is used to configure the IPv6 RA interval for an interface. Use the no form of this command to revert to the default setting. ipv6 nd ra interval MAX-SECS [MIN-SECS] no ipv6 nd ra interval Parameters MAX-SECS MIN-SECS Specifies the maximum interval between retransmission of RA messages in seconds. The valid range is from 4 to 1800 seconds. (Optional) Specifies the minimum interval between retransmission of RA messages in seconds. This value must be smaller than 0.75 times the maximum value. The valid range is from 3 to 1350 seconds. Default By default, the maximum interval value is 200 seconds. Command Mode Interface Configuration Mode. Usage Guideline The following rules apply to the minimum RA interval value if the minimum value is not configured: If the maximum RA interval value is equal to or greater than 9 seconds, then the minimum value will be 33% of the maximum value. If the maximum RA interval value lesser than 9 seconds, then the minimum value will be the same as the maximum value. 84
