3. Configure management IP และทดสอบ Ping จาก Nexus Switch ไปยัง Laptop ที่ใช้งานเป็น FTP Server
เครื่อง Laptop สำหรับการใช้งานเป็น FTP Server : IP = 192.168.1.20/24
Nexus switch ที่ Interface mgmt 0 : IP = 192.168.1.100/24
switch(config)# int mgmt 0 switch(config-if)# ip address 192.168.1.100/24 switch(config-if)# end switch# switch# ping 192.168.1.20 vrf management PING 192.168.1.20 (192.168.1.20): 56 data bytes 64 bytes from 192.168.1.20: icmp_seq=0 ttl=127 time=1.638 ms 64 bytes from 192.168.1.20: icmp_seq=1 ttl=127 time=1.093 ms 64 bytes from 192.168.1.20: icmp_seq=2 ttl=127 time=0.991 ms 64 bytes from 192.168.1.20: icmp_seq=3 ttl=127 time=1.203 ms 64 bytes from 192.168.1.20: icmp_seq=4 ttl=127 time=0.948 ms --- 192.168.1.20 ping statistics --- 5 packets transmitted, 5 packets received, 0.00% packet loss round-trip min/avg/max = 0.948/1.174/1.638 ms switch#
4. ตรวจสอบ Free Disk space
