Ethernet Statistics

To access this page, navigate to Network Configuration > Ethernet Statistics.

This page displays information on transmit and receive rates as well as throughput, error and collision information as shown below:

Ethernet statistics

There are two additional Ethernet statistics pages:

  • Ethernet Statistics (per port) - Aggregation ports - this page contains network information on a per aggregation basis, for example, ag1, ag2...
  • Ethernet Statistics (per port) - Physical ports - this page contains network information on a per physical port basis, for example, tg1, tg2...

Navigate to the Network Configuration > Ethernet Statistics (per port) page in order to view the Aggregation ports page. On this page, there is a link to the Ethernet statistics (per port) - Physical ports page.

TCP/IP Statistics

To access this page, navigate to Network Configuration > TCP/IP Statistics.

This page displays information on connections, segments, UDP, ICMP and TCP as shown below:

Additional commands

The NAS server also provides the following CLI commands which display information on the current network health status:

  • agg - this command lists any existing aggregations
  • ethernetstats - this command displays statistics for each Ethernet interface
  • tcpstats - this command displays statistics for TCP protocol packets
  • udpstats - this command displays statistics for UDP protocol packets
  • ip-stats-other - this command displays statistics for all other IP protocol packets
  • icmpstats - this command displays statistics for ICMP protocol packets
  • icmpv6stats - this command displays statistics for ICMP v6 protocol packets
  • arp - this command displays the IP to MAC address mappings
  • ndp-dump - this command displays the IPv6 to MAC address mappings and also displays any on-link prefixes and discovered routers
