cisco ucs 220 v4 server
esxi 5.5 custom image for cisco
2 physical 2 vmnics
currently have 1 vswitch. managment network(vmnic0) is configured on this vswitch. trying to setup vmkernel port for iscsi traffic using the other nic/vmnic1. i am able to click through and configure from the 'add network wizard' and when i click finish, vsphere spins and spins. after a minute it is no longer able to communicate over management port. i have to log into the console of esxi and restore network settings and then re ip the management network to get reconnected.
what am i doing wrong? any help would be appreciated. Thank you
