| + | ===== Log ===== | ||
| + | ==== Jan 12th ==== | ||
| + | * After restarting both **Server_Room** and **5th_Floor** I could not get link between the switches to come up on 10G reducing speed to 1G brings the link up but produces a log CRC errors and the connection is drop once every 10-20 secs even when using 1G sftps | ||
| + | * Any fiber run that is dropping seems to have some sort of CRC errors | ||
| + | * run from **Ag_Room** to **OLD_KSU** giving CRC errors on **OLD_KSU** port 1:53 even after restarting both switches reconfigured both ports to 1G and CRC errors stopped | ||
| + | * After reconfiguring both ports back to 10G the CRC errors seemed to have stopped | ||
| + | * Run from **server room** to **5th floor** stayed down after restarting both switches. Link did come up after reconfiguring both ports to 1G, both both 1:31 on server room switch and 1:54 on 5th floor switch had CRC errors | ||
| + | * As of 8pm on Friday all other switches showing 0 CRC errors | ||
| + | * Fibers in **Ag_Room** are transposed from the port descriptions. | ||
| + | ==== Jan 13th ==== | ||
| + | * Over the night of the 12th of Jan EAPS master reporting <Info:EAPS.RxPduLinkDown> on **Office** and **OLD_KSU** switches | ||
| + | * reduced speed of **Ag_room** and **OLD_KSU** switches to 1G seeing if CRC errors are causing <Info:EAPS.RxPduLinkDown> on EAPS master | ||
| + | * **Office** switch is having port 1:54 lose connection every hour or so, even after multiple restarts | ||
| + | * **Elementary_LD** port 1:54 had no issues until about (over 12hrs) 7am on Jan 13th then started loosing uplink every 1-2 min over a 5-10min period. Started again at 10:30am | ||
| + | * **Elementary_LD** was restarted and port 1:54 resumed normal operation | ||
| + | * Switched **Office** to **Elementary_LD** and **5th_Floor** to **Server_Room** over to using 1G sftp on the front of each switch and reconfigured EAPS ring to use different ports as of **12:01pm** | ||
| + | * single mode fiber link between **Elementary_LD** to **Business_AD_RM** started dropping a lot reducing speed to 1G to see if that stops the dropping **12:20pm** | ||
| + | * **12:25pm** After reducing both links to 1G only one side would get a connection reverted to 10G and rebooted **Elementary_LD** and **Business_AD_RM** | ||
| + | * **4:30pm** Pulling sftps off the ftp+ module seems to be fixing the issues. But still having issues between **OLD_KSU** to **5th_Floor** planning on fixing moving link to front sftp ports | ||
| + | * It's starting to look like we have two bad ftp+ modules in **5th_Floor** and **Elementary_LD** | ||
| + | ==== Jan 14th ==== | ||
| + | * **10am** moved other sftp from ftp+ module to front sftp ports on both **5th_Floor** and **OLD_KSU** switches | ||
| + | * **3pm** still getting about 1 drops/hr on **OLD_KSU** to **Ag_Room** link and 4-6 drops a hr on **Elementary_LD** to **Business_AD** all other links are staying up | ||
| + | * **6pm** it looks like we have a bad ftp+ module in **5th_Floor**, **Elementary_LD** and a failing module in **OLD_KSU** or **Ag_Room** | ||
| + | ==== Jan 15th ==== | ||
| + | * **7:30am** moved other sftp from ftp+ module to front sftp ports on both **Ag_Room** and **OLD_KSU** switches | ||
| + | * **8:30am** link between **Ag_Room** and **Business_AD** started dropping | ||
| + | * **8:51am** moved back to 10G sftp+ on **OLD_KSU** for **Ag_Room** link | ||
| + | * **9:00am** moved other sftp from ftp+ module to front sftp ports on both **Ag_Room** and **Business_AD** | ||
| + | * **11:00am** it looks like only one link is dropping: 1:54 on **Elementary_LD** | ||
