I recently tried to install a WAE-512 at one of our sites as an inline deployment.
The site has 2 routers, one is the main data router and is the HSRP active router for the data vlan. The other router is the main voice router and is the HSRP active router for the voice VLAN. The reason we have different routers as the gateway for each VLAN is that we need all voice traffic to go through the voice router as it has SRST capabilities, therefore under normal operating conditions, we expect voice traffic to hit the voice router, and then go over to the data router to get onto the WAN/Call manager.
I planned on optimising both connections using the WAE, thus utilising all ports on the inline adaptor.
What's occured to me is that voice traffic will actually be passing through the WAE twice at this site - once through inline pair 1 to get to the backup router, then through inline pair 0 to get to the main router.
When we installed it this morning, there were connectivity problems between the switch and the voice router.
What I need to know is, what are the effects of the traffic passing through the same WAE twice? Is this not a good idea? Could it potentially have caused the problems we had?
The voice traffic itself is UDP so I wouldn't expect the WAE to do anything with it in any case.
Many Thanks in advance,
