ping on VLAN group

I have a similar issue

 

 

... I have active and standby in v. 9.3.1 and use VLAN group and have a problem with sync

 

here is detail ....when use command ping peer

 

Active will lost packet around 90% (have problem)

 

Standby will lost packet around 10% (no problem)

 

 

So when Active want to sync to peer .. Sync is failed

 

when I see ARP table .... In standby unit I see MAC and vlan (internal) correct

 

but in Active unit I see MAC correct but Vlan is external ???

 

 

So I see when Active ping peer ... it's send packet through vlan external (actually should be internal) but problem is IP (both primary self and peer self) is in same address space

 

 

How to work out?

 

 

Thank you in advance

arp table (crop only self active and standby) http://upic.me/i/z9/otarp.png (41.44 is self standby unit , .41.40 is self active unit ) *(this is in same address space )

 

this config vlangroup

 

vlangroup DMZ-Groups {

 

tag 1

 

transparency transparent

 

bridge in standby disable

 

member DMZ-VLANs-Inbound DMZ-VLANs-Outbound

The standby LTM2 cannot ping a host in internal vlan while active LTM1 can, is it normal? why?have you configured proxy exclusion list?

BIG-IP version 9.3.1 is in this known issue list , so i can't use Proxy Exclusion List
