The 9k does however get a huge win with the ability to apply a ‘pie’ or software patch while staying in service vs requiring a reload.
SMUs are often "hitless", which is to say, "hitless" with scary quotes. What this means in practice is that the SMU itself might be hitless but it will depend on 47 other SMUs, thereby almost guaranteeing some form of reload. Also, restarting processes is "hitless" (e.g. restarting bgpd, ospfd, etc) or shutting down interfaces. E.g.: CSCuo47663: "Hitless/Optional SMU,aigp metric different in RIB & BGP table". This will restart the bgp process. CSCus26923: "traffic from SIP700 to 9000v is dropped when a link to 9000v flaps". Release notes state that the issue is not service impacting, then "After the SMU installation , we need to apply shut/noshut of the problematic interface to trigger the hardware programming." Wuh?? In other words, "hitless" does not mean "not service impacting". Nick
