Opened: Nov 24, 2020

Severity: 3-Major

Symptoms

Gratuitous ARP (GARP) messages are dropped at the time of sending GARP because the number of links up in the trunk is 0 (which returns "error 18" ... ERR_NOT_FOUND)

Impact

Neighboring device arp table is not updated about the BIG-IP interface status, because no gratuitous ARP message is sent out.

Conditions

-- Two BIG-IP systems with switchless configuration, such as i2xxx and i4xxx. -- Bring down and up the interfaces at the same time in the trunk.
