IP
If you are running an HPE Aruba (formally ProCurve) switch you may come across cases where your switch (in the example above a 5400R zl2) has multiple IP Addresses/VLANs and you need it to talk to another service (in my case syslog and sFlow receivers) on a set interface.
When this occurs you can use the ip source-interface command (make sure you are in config mode first) to define the IP Address or VLAN that you want the switch to talk out on. In my case VLAN2 which is used as the management network for the network switches (VLAN1 being the default network that switches use if multiple addresses are configured).
