NimbostratusLoad Balancing From Radius
we will use F5 to load balance accouting packtes from Radius server to database servers .
the issue is that Radius may send accouting packets with same source port ( ie : same src & dst ips , same src & dst port ) to F5 VIP .
F5 will drop this considreing this as duplicate packets or what ?

Wouldn't the same src and dst ip and port be used in most IP communications, RADIUS or otherwise?
SSHSSH_97332Radisu server sends accounting packets to database servers ( to VIP on F5 containing pool of databsae servers ) .
the idea is that Radius server may send same packet ( same l4 headers ) mutiple times- What_Lies_Bene1Just out of interest, why would it do that? Regardless, I think the only way to find out would be to do a test and monitor with tcpdump. I'd be keen to know what the result is.
- SSHSSH_97332Thanks , my traffic is in production si i may need a downtime .
does the below says that F5 will not drop UDP duplicate packets :

The article isn't too explicit but this is: http://wiki.wireshark.org/DuplicatePackets - doesn't look like you have a problem although you might need to use the feature described in the article you listed.
