Alert rula fail

Hi Everybody.

I have tried set a new high traffic rule on interfaces with macros.port_in_usage_perc great 95 percent.
After that I got a alarm from one of my cisco c2960x device. The affected sys Object ID is .1.3.6.1.4.1.9.1.1208 ifDesc Vlan1 . When I try to connect via snmp-get command I got this.

iso.3.6.1.4.1.9.1.1208 = No Such Object available on this agent at this OID

Librenms detail log said this
