When there is only one supervisor module, why does it show sup-1 and sup-2 in show boot command?
N1Kv-1-v5_2# sh boot
Current Boot Variables:
sup-1
kickstart variable = bootflash:/n1000v-dk9-kickstart.5.2.1.SV3.1.2.bin
system variable = bootflash:/n1000v-dk9.5.2.1.SV3.1.2.bin
sup-2
kickstart variable = bootflash:/n1000v-dk9-kickstart.5.2.1.SV3.1.2.bin
system variable = bootflash:/n1000v-dk9.5.2.1.SV3.1.2.bin
Boot Variables on next reload:
sup-1
kickstart variable = bootflash:/n1000v-dk9-kickstart.5.2.1.SV3.1.2.bin
