RX packets dropped ratio too high-gigamon-GigaVUE-OS
Vendor: gigamon
OS: GigaVUE-OS
Description:
Indeni tracks the number of packets that had issues and alerts if the ratio is too high.
Remediation Steps:
Packet drops usually occur when the rate of packets received is higher than the device’s ability to handle.
How does this work?
Login to the device’s CLI, change to enable mode and issue “show port stats”. This would present a table with statistics about the all the ports.
Why is this important?
Need to determine which ports are dropping packets on ingress. Dropping ingress packets on a network port indicates that too much traffic is coming from either a TAP or SPAN, and would require the admin to provision a higher speed port (1G -> 10G -> 40G -> 100G). When a tool port shows ingress packet drops it indicates that too much traffic is being aggregated from the network ports and would require either the configuration of a GigaStream (LAG) or provision of higher speed ports.
Without Indeni how would you find this?
The traffic statistics of network interfaces can be manually reviewed through the CLI.
