F5 LTM setup with Cisco FWSMs

The standby BigiP unit got disconnected, to move its fiber connection.

 

 

Opened a ticket on it, and they said the active unit didn't see traffic...so vlan failsafe tried to failover. Eventually....Networking then opened a ticket with Cisco, and they pointed to how the FWSM is handling vlans. Which is managed by the IT Security group. And, its somewhere between networking and it security on whether it'll get resolved now.

 

 

From what I've gathered....our core is a dual ring network (though nothing that would resemble a ring)...and it presents to us as a pair of 6509's in the datacenter....where the F5's are connected to different 6509's.

 

 

From what I read, the 6509 reached end of HW support on November 30th, 2012. The 6509-E is the replacement. Not sure what 6500 series stuff is in the core. But, they've been working on getting Nexus stuff going on the other side of the datacenter for some time...so that's likely what we'll all be converting to soon.

 

 

Someday soon they hope to be able to deliver gig to every jack. Though does it count in buildings are still wired with 10Base5 and/or 10Base2? Though I'm on the otherside of the datacenter door, and I don't have gig yet....

 

 

Actually, we're doing serial failover. But, we used to be on Extreme switches (that had problems doing STP), and traffic would go into loops and sometimes we would find traffic to active side would stop, but standby side was working. So, we added vlan failsafe to try to deal with this.
