ClusterXL long switching time by failover

[Izzio]

Hello!

I'm setting ClusterXL in Hot Standby new mode on SPLAT R55 HFA13 over 2 Cisco 3750 switches. Everything works fine but by a failover the switching time is relatively long: about 1 minute!
I know from previous installations that normally should be no more than 10sec.

Hat somebody any idea?

Thanks
Maurizio

How is formed the MAC of the Cluster ? could be the gratious arp is not been accepted by the switches has sould be......

In HA (Hot standby) mode the Cluster IP MAC = Active Member MAC (e.g.: 00:16:35:06:1F:33)

In Load Sharing a Mcast MAC is used.

In both cases the failover switching takes about 1 minute.

Thanks,
Maurizio

The problem was probably not a real problem ;-)
...and anyway has concerned just only ping to cluster IP.

Adding following line:

fw_allow_simultaneous_ping=1

to $FWDIR/boot/modules/fwkern.conf is everything ok!

See also another post in this forum for details.

Ciao

Up to 50 s? If so, it may be spanning tree. Did you set "port fast"?
