I am finding some contradictions in Cisco documentation about the LAG support in 2504 WLC. On one hand, the Cisco 2500 Series Wireless Controller Deployment Guide clearly states:
Note: Link Aggregation (LAG) is not supported on the Cisco 2500 Series Wireless Controller.
On the other hand, the brochure Cisco Wireless LAN Controllers at a glance states 2504 does support LAG.
After some search, I have found the bulletin for Cisco Unified Wireless Network Software Release 7.4 stating:
Wireless Controllers 8500, 2500, and Flex 7500 now support Link Aggregation Group (LAG).
What makes me think the LAG support in the 2504 would be depending on the software version loaded on the device.
Since the only 2504 I can work on is having 7.2 software version and is in a production environment (not easy to upgrade and test on it), I still wonder:
- Does the 2504 WLC really support LAG?
- Does it require a minimum software version or any additional hardware for it?
- Is it having any limitation or is the same LAG functionality as in 5500 WLC series?
