I have a X450e that I am linking a Cisco 2960S too. Both ports are in VLAN 99 (management). They are not able to talk to each other and I am not able to access the Cisco switch by the IP assigned to VLAN 99.
switchport access vlan 99
configure vlan Mgmt99 add ports 1-2, 39-42 untagged
Thanks for any assistance you can provide.
