Hi, I'm new to this forum, so please go easy on me. I need some guidance please. We have a pair of N2048 switches. We are using them to help us get our web network operating in HA, no SPOF.
The switches are operating with MLAG.
A pair of Cisco ASA's are connected using a port channel of 2 ports to each ASA (1 from each switch). The ASA's are configured Active/Standby.
6 Hypervisors each connected with port channel of 6 ports (3 from each switch), connected as trunk, LACP all ports active.
2 Barracuda ADC Load Balancers. Each LB has 4 ports. We have 2 ports for outside connections, 2 ports for inside connections, again split up between the 2 switches on the MLAG. The LB's though keep the standby unit ports up, and use VRRP and GARP when a failover occurs.
Problem is the load balancers. No matter what we do, failover and failback never work for the load balancers. When I initiate failover, it seems that the switches won't allow the ARP to move to the newly active LB unit. Everything else works perfect. I think it's something with either Spanning Tree or LACP.
Anyone have any kind of experience at all close to this, or can point me in a direction to look. I have a test lab environment I can work with, and if configs will help, I will be more than happy to post them too.
Thanks in advance for any and all help.
