Rename interfaces?

Hi, Is there a way to rename the 'interface'-fields on a switch? We have some (really) old switches (Netgear FSM726) that has really long interface-names; "FSM726 Management Switch 10/100 Mbps Ethernet Network Interface 1", which kinda breaks the "Switch port status"- and "Switch port activity"-tabs on the "IP Device Info"-page of the devices in question. Could I change this in the DB in some way? Or will it just be overwritten next time navcron runs? -- Joachim
