Sorry, forgot to write the next steps: 1 Update firmware 2. Update boot 3 After the upgrade, the switch was made available only through the console in debug mode, and through the WEB. Initiated a variety of boot firmware and rebooted - switch earned in the normal mode. 4. delete startup-config and reload 5 Configuration of the device through the console. I hope this problem will not happen again, because restart the device does not help.
I have a 5524 linked to a 5548 in my server cabinet, and increasingly I'm seeing a drop in internet connection from the user's perspective...   The 5524 runs from Port 1 to port 47 of the 5548   The 5548 runs from port 48 to firewall   Firewall runs direct to Comcast Router...   I've got a PC monitoring PING's:   01) From the 5524 to Google's DNS @ 8.8.8.8 02) From the 5548 to Google's DNS @ 8.8.8.8 03) Outside the Firewall to Google's DNS @ 8.8.8.8   The ISP (Comcast) reports, no loss I have NO issue outside the Firewall I have NO report of a drop ON the Firewall   And TWICE today I've lost Internet connectivity and the RAM log on the 5548 says"     RAM Log on the 5524 says:     I could understand if the secondary switch (the 5524) going down or losing internet connectivity if it's port 1 to the 5548's Port 47 choked, but WHY would the 5548 Choke???    
Dell 5548 Keeps losing Internet Connection, but reporting "Blocking"? Confused?
