Operating instructions

122 Cisco Systems Intelligent Gigabit Ethernet Switch Module
– Repeat for the next Cisco Systems IGESM.
4. Configure the blade server ports on the server blades:
– Configure any desired teaming or SLB, or both.
– Configure any desired VLANs/trunking.
– Configure any desired access links.
– Configure desired IP address.
– Repeat for the next blade server.
5. Re-enable or recable the links that were disabled in step 1 (Table 7-2 on page 123).
6. Confirm the desired operation of the configuration.
Summary of disconnect procedure to be performed for each example
When performing initial configurations or making changes to existing configurations that might
have an impact on Spanning Tree (such as changing link aggregation), we recommend that
you leave connections uncabled, or shut down, before making the configuration changes.
This will reduce the likelihood of any temporary Spanning Tree loops and possible network
down conditions that might result in the process of adding or changing configurations.
Table 7-1 shows three basic options to disable the connection. Choose the one most suited to
your situation. For example, if you will not be physically at the equipment while you are
performing the configuration, physically disconnecting the cables is not your best option.
