CDP must be enabled on non-cluster ports for neighbor information to appear for those ports.

Display information about all CDP-compliant devices that are connected to the ports on a node in the cluster:. Hold time is the period of time for which CDP advertisements are stored in cache in neighboring CDP-compliant devices.

The value of the cdpd. The default hold time value is seconds, but you can enter values ranging from 10 seconds to seconds. If an IP address is removed before the hold time expires, the CDP information is cached until the hold time expires.

You can increase or decrease the interval for sending CDP advertisements depending on network traffic and changes in the network topology. Configure the interval for sending CDP advertisements for all ports of a node, or for all ports of all nodes in a cluster:. You can view the CDP statistics for the cluster and non-cluster ports on each node to detect potential network connectivity issues.

CDP statistics are cumulative from the time they were last cleared. CDP must be enabled on non-cluster ports for statistics to appear for those ports. The following command shows the CDP statistics before they are cleared. The output displays the total number of packets that have been sent and received since the last time the statistics were cleared.

After the statistics are cleared, they begin to accumulate after the next CDP advertisement is sent or received. Using LLDP to detect network connectivity consists of reviewing deployment considerations, enabling it on all ports, viewing neighbor devices, and adjusting LLDP configuration values as needed.

LLDP must also be enabled on any switches and routers before information about neighbor devices can be displayed. The lldp.

You can view information about the neighboring devices that are connected to each port of the nodes of your cluster, provided that the port is connected to an LLDP-compliant device. You use the network device-discovery show command to view neighbor information. Display information about all LLDP-compliant devices that are connected to the ports on a node in the cluster:.

The output lists the LLDP-enabled devices that are connected to each port of the specified node. Preview file. I have this problem too. All forum topics Previous Topic Next Topic. Accepted Solutions.
