From what I've found, it doesn't appear that there is a way to pull it by SNMP, unfortunately.
Hello! Does anyone know how to get the value of the optical signal level on the interface on the switch Dell Force 10 S2410-01-GE-24P using SNMP? At the moment unit is not responding to telnet commands and i dont know why, but it responds to snmpwalk(get) commands of linux servers.
