Bug ID 967101: When all of the interfaces in the trunk are brought up, Gratuitous ARP is not being sent out.

Last Modified: Nov 07, 2022

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
14.1.0,,,,,, 14.1.2,,,,,,,,, 14.1.3,, 14.1.4,,,,,, 15.1.0,,,,,, 15.1.1, 15.1.2,, 15.1.3,, 15.1.4,, 15.1.5, 16.1.0, 16.1.1, 16.1.2,

Fixed In:

Opened: Nov 24, 2020

Severity: 3-Major


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)


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


-- 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.
