Confirming Connectivity on the Network
After connecting your switch, take the time to ensure connectivity by pinging an external IP address, and pinging a domain to ensure domain name resolution. From Release 5.0.0 onwards, ping accepts IPv6 addresses also.
To ping the external network from the switch, use the ping command:
CLI network-admin@switch > ping 2010::2
PING 2010::2(2010::2) 56 data bytes
64 bytes from 2010::2: icmp_seq=1 ttl=64 time=1.69 ms
64 bytes from 2010::2: icmp_seq=2 ttl=64 time=0.412 ms
64 bytes from 2010::2: icmp_seq=3 ttl=64 time=0.434 ms
64 bytes from 2010::2: icmp_seq=4 ttl=64 time=0.418 ms
 
CLI network-admin@switch > ping 98.138.253.109 : 56 data bytes
PING 98.138.253.109 (98.138.253.109) 56(84) bytes of data.
64 bytes from 98.138.253.109: icmp_seq=1 ttl=47 time=51.8 ms
64 bytes from 98.138.253.109: icmp_seq=2 ttl=47 time=51.9 ms
64 bytes from 98.138.253.109: icmp_seq=3 ttl=47 time=53.6 ms
 
Use the ping command again to ping a domain:
CLI network-admin@switch > ping yahoo.com
PING yahoo.com (98.138.253.109) 56(84) bytes of data.
64 bytes from ir1.fp.vip.ne1.yahoo.com (98.138.253.109): icmp_seq=1 ttl=47 time=52.2 ms
64 bytes from ir1.fp.vip.ne1.yahoo.com (98.138.253.109): icmp_seq=2 ttl=47 time=52.5 ms
64 bytes from ir1.fp.vip.ne1.yahoo.com (98.138.253.109): icmp_seq=3 ttl=47 time=51.9 ms
64 bytes from ir1.fp.vip.ne1.yahoo.com (98.138.253.109): icmp_seq=4 ttl=47 time=51.8 ms
