BIG-IP All(all modules)

Known Affected Versions:
13.1.0, 13.1.0.1, 13.1.0.2, 13.1.0.3, 13.1.0.4, 13.1.0.5, 13.1.0.6, 13.1.0.7, 13.1.0.8, 13.1.1, 13.1.1.1, 13.1.1.2, 13.1.1.3, 13.1.1.4, 13.1.1.5

Opened: Jun 15, 2017
Severity: 4-Minor

Symptoms

Within AWS, instances of type i3.16xlarge and r4.16xlarge allow for up to 15 network interfaces. Use of more than 10 interfaces on BIG-IP instances will result in the extra interfaces not functioning. Interfaces 1.10-1.14 will have the same MAC address as 1.1 and not function.

Impact

The extra interfaces will not function.

Conditions

Use of i3.16xlarge or r4.16xlarge instances for BIG-IP with more than 10 network interfaces.

Workaround

Use multiple instances with fewer interfaces. Potentially use tunnels to separate traffic.

Fix Information

None
