In order to configure a custom name (IfAlias) for a device's SNMP interface, you need to access the device configuration console and rename each interface according to your naming convention preference.
After the interface(s) are renamed, you can add them as performance monitors and active monitors. You can also select the custom interface in various dashboard reports and split second graphs. If the device interface(s) already have performance monitors and/or active monitors set up, the new interface name displays in WhatsUp Gold accordingly.
Use the following example instructions for how to change a Cisco router interface name. If you have other devices, refer to the device documentation for instructions on how to change interface names.
To configure a device custom name for an SNMP interface on a Cisco router:
Cisco1812# configure
Cisco1812(config)# interface FastEthernet 9
Cisco1812(config-if)# description CUSTOM NAME
Cisco1812(config-if)# ^Z
Cisco1812#
