Be very careful about disabling the lower data rates. Negotiation for network access frequently occurs on base data rates, and if you disable them, it can cause association failure and loss of network access for wireless clients. This may or may not happen on your platform. Just ensure that you are not depending on those data rates as base data rates. -- Jason Trinklein Wireless Engineering Manager College of Charleston 81 St. Philip Street | Office 311D | Charleston, SC 29403 [email protected]<mailto:[email protected]> | (843) 300–8009

I admit to being new to supporting optimized roaming on Cisco controllers (after having easily supported this on Aruba controllers for the past several years, by using Client Match.) What are the pros/cons of implementing Optimized Roaming on Cisco Controllers? We don’t currently have it enabled here, and it may never have been before. One of the caveats before enabling it is “Disable 802.11a / 802.11b network before changing Optimized Roaming Interval value” … this means I have to disable the 802.11a and 802.11b/g networks on the controller, enable Optimized Roaming, tune the interval value, re-enable the 802.11a and 802.11b/g networks … this sounds like an outage, yes ? -- Will Dawes - Aruba ACMA Network Engineering and Architecture University Networking and Infrastructure Louisiana State University 200 Frey Computing Services Center, Baton Rouge, LA 70803 office 225.578.5926 [email protected]<mailto:[email protected]> ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.educause.edu_groups_&d=CwMFAg&c=7MSSWy9Bs2yocjNQzurxOQ&r=AuveJXIorHW4s-aGSHEbnQZt5LubWGCZik-5HxxaRqU&m=Dfg6e-775ZkTDHQT94Lr_1awA4agCyqQi9qcu-qlGtw&s=A9BWmG8s7y-YGObYUwpOd-EwSd1OpoAV61opSrFYR0c&e=>. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.educause.edu_groups_&d=CwMFAg&c=7MSSWy9Bs2yocjNQzurxOQ&r=AuveJXIorHW4s-aGSHEbnQZt5LubWGCZik-5HxxaRqU&m=Dfg6e-775ZkTDHQT94Lr_1awA4agCyqQi9qcu-qlGtw&s=A9BWmG8s7y-YGObYUwpOd-EwSd1OpoAV61opSrFYR0c&e=>. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.educause.edu_groups_&d=CwMFAg&c=7MSSWy9Bs2yocjNQzurxOQ&r=AuveJXIorHW4s-aGSHEbnQZt5LubWGCZik-5HxxaRqU&m=Dfg6e-775ZkTDHQT94Lr_1awA4agCyqQi9qcu-qlGtw&s=A9BWmG8s7y-YGObYUwpOd-EwSd1OpoAV61opSrFYR0c&e=>. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
