• Was the switch able to pass user traffic while the issue was occurring? 
• What was the LED status? (If the switch remains able to pass traffic, the port LEDs should continue to 
blink. In particular, during a broadcast storm, all of the port LEDs should be blinking.)
• Do the link LEDs continue to be lit on removal of the cable connected to the port?
• Was the switch accessible via Telnet, SNMP, and/or HTTP? 
• What type of traffic was flowing through the system? 
• Were any other S50s in the network experiencing the same problem? If not, are they positioned in the 
network differently? Are they passing different kinds of traffic? 
In addition, as a best practice, configure a remote management approach, such as SSH or HTTPS, to access 
an S-Series switch when console access is not possible but the switch is actively forwarding data traffic.
