Nimbostratus11.3 proxy ARP
Hello,
is it possible to disable Proxy ARP feature on v11.3 LTM?
When node goes down, LTM starts to respond to ARP requests from other nodes in
L2 LAN. When node goes up again, LTM continues to respond to ARP requests
making node unreachable to other nodes in that L2 VLAN.
Windows nodes detect this problem as 'IP address conflict'.
I think that this problem is related to v11.3 because we didn't experienced it
on v10.2.4.

are you talking about vlan group or arp response from virtual address (e.g. network virtual address, wildcard virtual address)? 
dukeNeither of this. :(
It is just node in VLAN and member in pool behind standard virtual server.
- nitassdo you have network or wildcard virtual address? if so, is arp enabled?
tmsh list ltm virtual-address - duke
Yes I have Forwarding VS with ARP enabled and several VLANs behind LTM.
Forwarding VS is enabled on ALL VLANs beacuse of management access.
ltm virtual WC_NETWORK_VS {
destination any:any
ip-forward
mask any
profiles {
fastL4 { }
}
source 0.0.0.0/0
translate-address disabled
translate-port disabled
vlans-disabled
}
[root@ltm-viprion:/S1-green-P:Active:Standalone] config tmsh show ltm virtual-address
-----------------------------------
Ltm::Virtual Address: any (0.0.0.0)

Availability : unknown
State : enabled
Reason : The children virtual server(s) either don't have service checking enabled, or service check results are not available yet
- nitassYes I have Forwarding VS with ARP enabled and several VLANs behind LTM.can you try to disable wildcard virtual address (0.0.0.0)'s arp?
