XML Configuration
Safe Mode
When inserting a new or replacement interconnect switch into a production environment, you
must be certain that the interconnect switch configuration is compatible with the production
network. Compatibility with a network can include items such as:
•
•
•
•
Non-corruption of the network in general—Corruption, such as loops, can occur within
the network without enabling Spanning Tree Protocol (STP).
Security of connected network entities—Security issues can arise as a result of
configuration items, including such attributes as subnet-to-subnet communication and
blade-to-blade communication where communication between these entities is not
acceptable.
Security of the interconnect switch itself—These attributes include controlled access to
the interconnect switch such as user-password and SNMP read-write community string.
Other configuration attributes such as VLAN settings.
The interconnect switch factory default, as well as previously configured interconnect
switches, may not have configurations that are compatible with the production network.
If the configuration of the interconnect switch is not compatible with the production network,
the interconnect switch may be pre-configured in a private network environment
There are several preconfiguration options. For example, the interconnect switch may be
configured for its exact position in the production network. Another option is to partially
configure the interconnect switch so that is is compatible with multiple positions in the
production network. The configuration can then be completed for the interconnect switch
through scripting, manual operation, or a configuration download. This more globally
appropriate configuration is called a "safe mode" configuration. Note that a single safe mode
configuration may or may not be appropriate for all production environments. A spare
interconnect switch, however, configured to a "safe mode" may be appropriate for multiple
production environments.
Interconnect Switch Replacement Scenario using a "Safe
Mode" Configuration
When an in-production interconnect switch fails:
1. Remove the failed interconnect switch.
2. Insert the spare interconnect switch that was previously configured for safe operation.
3. Upgrade to new firmware if appropriate.
4. Download the correct configuration for that particular interconnect switch.
