MAB (mac-authentication-bypass) not working on CAT4506E platform
- Due to 'EOL-concerns' we are currently migrating our office switches from cat4500-Supervisor II+ hardware platform to cat4506e switches using supervisor ' Sup 7L-E 10GE' ; IOS version = Cisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSALK9-M), Version 03.05.03.E.
I copied the running config from the old switches to the new platform quasi exactly ,of course changing stuff such was IP addr, hostname and a few other items.
It tuns out that on the new platform MAB isn't working. Debugging MAB and AAA show nothing appearing in the logs. It seems that MAB just isn't started if something is connected to a user port. MAB simply seems dead.
It seems as if I am missing something fundamental. Concerns are , which license level do I need for MAB on this platform (for instance) ? Does anyone have other tips and tricks ? Note that radius-config and port statements used make MAB work perfectly on the old switches.
Hello Rajeevsh , for us the sequence of MAB commands being used was not an argument since MAB was working on the old 4500.As Neno pointed out we downgraded to 3.4.4 and everyting worked fine since then!
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
