Are you using multibind interface?<br>

I had the problem with the ARP when the vlans are bind to

We do, however this problem appears on both multibind and static
interfaces with /24, /23 and /30 mask..<br>

I've set very long arp timeout to workaround this and don't know it was

<pre>We had this situation again, this morning.
I don't think it's solution here.
Behaviour is like that:
- everything works fine
- some entries disappear from arp-cache
- "sniffing" on dead hosts shows, that SmartEdge does not send any ARP
requests, nor responds for requests from remote hosts (only particular
ones).
- rest of host work fine, ARPs go in both directions.
- restart of arp process resolves this issue till next time (usually ~24h)

<pre>hello,
recently we had 2 cases, when some of the hosts on static VLANs
disappeard.
show arp-cache shows nothing related to those hosts, other hosts on the
same VLAN work fine.
restarting of arp process resolves this issue temporairly (till next
problem).
