3 steps for moving Cisco's Catalyst 6500 to the Nexus 9000

Jim Duffy | June 20, 2014
Cisco is anxious for data center switching customers to move to its new line and is recommending how.

For segmentation and security policy migration, Cisco recommends use of the Nexus Migration Tool to move application- and security-specific VLANs, VRF instances and ACLs for segmentation from the Catalyst 6500 DCSS to the Nexus 9508 DCSS for configuration on that system. Other considerations are Nexus 9508-specific features such as unicast, multicast, QoS, and VXLAN capabilities to be deployed according to application and business requirements.

Once these connections have been established, the third and last step is server and end device connectivity. Matching Nexus to Catalyst downlink interface configurations should be straightforward but migrating 100 or more servers might be a change management challenge, the Cisco document cautions.

If the server teaming configuration will remain unchanged, then the Nexus Configuration Tool can be used to convert the current Catalyst 6500 configuration to the Nexus 9508 interface configuration, then document states. But if the servers being migrated will use vPC or 10GBaseT, configuration templates will have to be used to manually reconfigure server connectivity.

Cisco provides a sample template for vPC server connectivity in the web document, which would result in a configuration like this:

After all the servers are migrated, the Catalyst 6500 EoR access switches can be decommissioned:

Cisco would not divulge financial incentives for the Catalyst 6500-to-Nexus 9000 technology migration program, such as trade-in pricing, rebates, buybacks, discounts or any other monetary terms. One reseller we spoke with says they are not any more aggressive than any other technology migration incentives.
