Get the VRRP-A Status via SNMP or aXAPI

Any suggestions on the best way to drain all connections from a server so that you can perform maintenance? In a non emergency situation I'd like to let active connections continue to a server but not to allow new connections.

URL Hash Persistence synced to standby HA node?
Hi, We recently implemented URL Hash Persistence on a rather large Varnish cache server farm on an AX3000 cluster running 2.4.3-p7.

Smart Flow Control limits
One of the settings on a Connection Reuse template is "Smart Flow Control", which lets you queue packets when the per-server connection limit is reached (otherwise packets that would exceed the limit are dropped). The queue depth is configurable, but then, if the queue is full, packets are dropped. I realize that if you…

Setting the port threshold for LACP trunks
Posted by pwidman Is there such a thing? I do not see it in the administrative guide for 2.6.1. I do see it for static trunks. If you do not recall what port threshold means: By default, a trunk’s status remains UP so long as at least one of its member ports is up. You can change the ports threshold of a trunk to 2-8…
