Configuring snmpd to send responses out of different ports or addresses

In 10.x, you can configure a TMM route and then the traffic should be sent out the corresponding interface from a suitable self IP on the egress VLAN.

 

 

You can do this using the GUI under Network | Routes or with the 'b route' or 'tmsh create net route' commands.

Outbound administrative connections

 

 

Outbound connections sent from BIG-IP by administrative applications (SNMP, SMTP, SSH, NTP, etc.) are processed by the Linux operating system. These connections may use either the management address or a self-IP address as the source address. The BIG-IP compares the destinaton address to the routing table to determine the interface through which BIG-IP routes the traffic.

 

 

Note: This behavior applies only to unsolicited outbound traffic: traffic that is not in response to a request originated by a remote host. A response to a request originated by a remote host will be returned to the last MAC address traversed by the inbound request.
