[5] When accessing NX-OS, users authenticate directly to their assigned privilege level. SSH server is enabled while Telnet server is disabled by default in ...
EtherChannel between a switch and a server. EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches.It allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.
