Hi Kevin, Ports 01 to 16 are internal - - > ports connected to a blade server Ports 17 to 24 are external - - > ports connected to an external switch
In your case, the port channel should be configured between the external ports and your external switch. The blade servers should not be part of the port channel. If you have a blade which is using more than one slot, you can create another Port channel between the Internal ports and the blade servers. You can't use the same port-channel between multiple devices. What you can do is : ++ remove the port-channel from port1 to 16. ++ Use one or 2 port channels between the blade center switches and your core switches Po1 (G0/20-22) connected to HP Core1 Po2 (G0/23-24) connected to another Blade Switch (Internal port) or connected to HP-CORE2 direclty Depends if you wa Best Regards, # - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - # - - Nicolas KARP # - - Network and Security Engineer # - - Email : [email protected] <[email protected]> # - - Linkedin : http://www.linkedin.com/in/nicolaskarp # - - Viadeo : http://www.viadeo.com/fr/profile/nicolas.karp <http://www.viadeo.com/fr/profile/nicolas.karp%20> # - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 2013/2/19 Kevin Berry <[email protected]> > I have (2) Cisco blade switches running in redundant mode and each is > connected to the same HP ROOT switch on the other end.
