2006-10-23: Network Down

Cause: all servers were reset to synchronize the current time. All BACH's VLAN interfaces failed, and could not be reset by enabling/disabling the interfaces.

Fix: All network interfaces were removed and reconfigured manually. BACH was also reset. VLANs returned to normal after repeating the procedures for several times.

B403 Network Down (2006-10-11, 20:25)

Cause:

- file over 100MB in size was being copied by ~10 students simultaneously

Problem:

- B403 Network down; all workstations were unable to connect to BACH and other servers
- other networks remained intact
- ping test for all other networks were OK
- Strange thing: ping stopped when 172.16.14.11 was ping'ed (the IP for B403 VLAN bound on BACH).

Fix:

- INETCFG on BACH
- go to "Binding" and disable the IP on BACH bound on the B403 VLAN (ie. 172.16.14.11)
- go to "Interface and dsisable the Virtual board for B403 VLAN
- reinitialize system
- go to "Binding" and "Interface" again to enable the IP and the virtual board.
