Cumulonimbusdo you see anything in the arp table on the f5 (in tmsh 'show net arp', from bash 'arp -n') or your laptop? are any AFM or packet filter rules defined on the f5 that could prevent ICMP to/from the self-IP? have you tried running tcpdump on the f5?
f5 config should be vlan with necessary interface as untagged. unique self-ip should be assigned to that vlan as traffic-group-local-only.
you could try another interface

CirrusI do not see anything in the dynamic arp table of F5 its empty. Haven't checked in laptop.
There is not packet filter as its disabled, no AFM. I have tried tcpdump during which i tried pinging self ip from cisco. there were few arp requests in tcpdump and icmp request from cisco to F5 but no icmp reply packet in tcpdump.
rest of the configurations are as you mentions. I have not idea why its not pinging.
its platform LTM 2000s 11.2. Will upgrading the OS will solve the problem?
