Common troubleshooting issues

The following describes general issues that may prevent your BCM system from functioning
properly.
If your BCM 4.0 (or SRG 1.5) system does not function after the upgrade and the problem cannot
be corrected by other troubleshooting methods.
Recommended action: Revert your system back to the pre-upgrade status (BCM 3.6/3.7 or
SRG 1.0) and attempt the upgrade again.
1
Use BIT to image your BCM system to a factory BCM 3.6/3.7 system. Refer to the BCM
Imaging Tool User Guide.
2 Restore the BCM 3.6/3.7 data to your system
3
The BCM system is now back at the pre-upgrade configuration. You can attempt the
upgrade again.
If you cannot connect to the BCM system with Element Manager:
Recommended action: In a BCM 4.0 (or SRG 1.5) system there is no inbound IP filter rule to
allow the OAM port. Therefore, you are not able to connect to the BCM system with Element
Manager when the firewall is turned on. In this case, you must turn off the firewall. You can
then connect to the system with Element Manager and create the IP filter rule. To enable the
firewall on the BCM system, create a filter rule to allow the required port, then enable the
firewall (Configuration > Data Services > NAT and Filters > Interfaces).
