• Check the LACP settings on the switch. If you are using link aggregation on the
BlackPearl system, the switch MUST be configured to use LACP on those ports. If you
are not using link aggregation, the switch must be configured NOT to use LACP on
those ports.
• Check the VLAN (Virtual Local Area Network) settings on the switch. Ensure that the
ports are assigned to the correct VLAN.
Tools
Ping
The ping command is a simple tool, based on a request-response mechanism, to verify
connectivity to a remote network node. The ping command is based on ICMP (Internet
Control Message Protocol). The request is an ICMP Echo request packet and the reply is an
ICMP Echo Reply. Like a regular IP packet, an ICMP packet is forwarded based on the
intermediate routers' routing table, until it reaches the destination. After it reaches the
destination, the ICMP Echo Reply packet is generated and returned to the originating node.
For example, to verify the connectivity from the switch to the IP address 192.168.2.10, run
the command shown below from the switch command line or client:
ping 192.168.2.10
All ICMP Echo requests should receive replies including information about the round trip
time it took to receive the response. A response of 0 msec means that the time was less than
1 ms. If the request times out, then check the settings on the switch to which the BlackPearl
system is connected.
