Well, with one swift command you can display temperature and fan status and internal temperatures of your routers. Let's look at three examples of the Show Environment command and how it displays information based on different routers and switches.. Execute one of the following commands to check the status of fans on Cisco equipment. Use the ' show environment | include fan-tray ' command to check Fan-Tray status.
I have 4000, 4500 and 6500 switches - how would i determine what fan tray I have in my switch?. 1. do we need to create custom views with custom OIDs in the switch's SNMP configuration? Usually not. Are you using SNMPv2c? 2. by default the switch chooses UDP port 162 for SNMP operation, just want to confirm if it works on 162 or 161 ( i have tried on both but to no good, just want to check to be sure).
