Chapter 5: Basic Switch Management
100 Section II: Basic Operations
Pinging Network Devices
If the switch is unable to communicate with a network device, such as a
syslog server or a TFTP server, you can test for an active link between the
two devices by instructing the switch to send ICMP Echo Requests and to
listen for replies sent back from the other device. This is accomplished
with the PING command in the Privileged Exec mode.
This command instructs the switch to send ICMP Echo Requests to a
network device known by the IP address 149.122.14.15
awplus> enable
awplus# ping 149.122.14.15
The results of the ping are displayed on the screen.
Note
To send ICMP Echo Requests, the switch must have a management
IP address. For instructions, refer to Chapter 9, “IPv4 and IPv6
Management Addresses” on page 201.
Note
The switch sends the ICMP Echo Requests from the ports of the
VLAN assigned the management IP address. The device the switch
is pinging must be a member of that VLAN or must be accessible
through routers or other Layer 3 devices.
For reference information, refer to “PING” on page 123.
