Which port (e0a,e0M, etc)is used to send autosupport traffic? Can this be modified?

I need to determine which interface autosupport SMTP traffic is generated from in order to add to Exchange as relay... Also, is this modifiable?

Re: Which port (e0a,e0M, etc)is used to send autosupport traffic? Can this be modified?

It all depends on routing.

Run command 'route -s' to determine which interface is used to reach the mail relay.

If e0M is in the same range as another interface, then it is better to disable e0M because this interface only runs at 100Mbps-fd.

So the e0M is on the management VLAN per best practices. Are you implying that 100M is not sufficient for the ASUP traffic? Is there any way to manually set the route? It sounds like you are saying that the filer will take the shortest hop to the SMTP server…

Not necessarily.

What I mean is that you have to be careful that de default route does not use the e0M interface because it only operates at 100Mbps. So make sure that the default route is not in the range of the e0M interface.

If your SMTP server is in another IP range than the e0M interface, than you can check which route/interface is used by checking the routing table (command = route -s).

I usually disable the e0M interface and create an extra VLAN one of the 1Gbps interfaces just to make sure that in no circumstance the e0M interface is used for production network traffic.
