Last Modified: Jul 12, 2023

Affected Product(s):
BIG-IQ Platform(all modules)

Opened: Mar 23, 2020

Severity: 4-Minor

Symptoms

If you install BIG-IQ without rolling forward a previous configuration and use IPv6 address for the management port it fails and with the following error: Error: (/config/bigip_base.conf at line 4) fd32:f5:0:a1::143/64/ffff:ffff:ffff:ffff:: contains an invalid netmask.

Impact

BIG-IQ is inoperative and unreachable.

Conditions

This occurs with a new installation of BIG-IQ without a previous configuration.

Workaround

Login to console. Remove /64 from bigip_base.conf from the value of sys management-IP i.e change "fd32:F5:0:a1::143/64/ffff:ffff:ffff:ffff::" to  "fd32:F5:0:a1::143/ffff:ffff:ffff:ffff::". After this perform the steps below: 1. tmsh save sys config. 2. tmsh modify sys global-settings mgmt-dhcp disabled 3. tmsh create net vlan <vlan_name> interfaces add { 1.1 } 4. tmsh create net self <ipaddress/cidr> vlan <vlan_name> allow-service default 5. tmsh save sys config
