Monitor Internet Protocol Service

With NetQ, a user can monitor IP (Internet Protocol) addresses, neighbors, and routes, including viewing the current status and the status an earlier point in time.

It helps answer questions such as:

  • Who are the IP neighbors for each switch?
  • How many IPv4 and IPv6 addresses am I using in total and on which interface?
  • Which routes are owned by which switches?
  • When did changes occur to my IP configuration?

The netq show ip command is used to obtain the address, neighbor, and route information from the devices. Its syntax is:

netq <hostname> show ip addresses [<remote-interface>] [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [around <text-time>] [count] [json]
netq [<hostname>] show ip addresses [<remote-interface>] [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [around <text-time>] [json]
netq show ip addresses [<remote-interface>] [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [subnet|supernet|gateway] [around <text-time>] [json]
netq <hostname> show ip neighbors [<remote-interface>] [<ipv4>|<ipv4> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [json]
netq [<hostname>] show ip neighbors [<remote-interface>] [<ipv4>|<ipv4> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [count] [json]
netq <hostname> show ip routes [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [count] [json]
netq [<hostname>] show ip routes [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [json]
    
netq <hostname> show ipv6 addresses [<remote-interface>] [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [around <text-time>] [count] [json]
netq [<hostname>] show ipv6 addresses [<remote-interface>] [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [around <text-time>] [json]
netq show ipv6 addresses [<remote-interface>] [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [subnet|supernet|gateway] [around <text-time>] [json]
netq <hostname> show ipv6 neighbors [<remote-interface>] [<ipv6>|<ipv6> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [count] [json]
netq [<hostname>] show ipv6 neighbors [<remote-interface>] [<ipv6>|<ipv6> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [json]
netq <hostname> show ipv6 routes [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [count] [json]
netq [<hostname>] show ipv6 routes [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [json]

When entering a time value, you must include a numeric value and the unit of measure:

  • w: week(s)
  • d: day(s)
  • h: hour(s)
  • m: minute(s)
  • s: second(s)
  • now

For the between option, the start (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.

View IP Address Information

You can view the IPv4 and IPv6 address information for all of your devices, including the interface and VRF for each device. Additionally, you can:

  • View the information at an earlier point in time
  • Filter against a particular device, interface or VRF assignment
  • Obtain a count of all of the addresses

Each of these provides information for troubleshooting potential configuration and communication issues at the layer 3 level.

View IPv4 Address information for All Devices

To view only IPv4 addresses, run netq show ip addresses. This example shows all IPv4 addresses in the reference topology.

Obtain a Count of IP Addresses Used on a Device

If you are concerned that a particular device an overload of addresses in use, you can quickly view the address count using the count option.

This example shows the number of IPv4 and IPv6 addresses on the leaf01 switch.

cumulus@switch:~$ netq leaf01 show ip addresses count
Count of matching address records: 9

cumulus@switch:~$ netq leaf01 show ipv6 addresses count
Count of matching address records: 17

View IP Neighbor Information

You can view the IPv4 and IPv6 neighbor information for all of your devices, including the interface port, MAC address, VRF assignment, and whether it learns the MAC address from the peer (remote=yes). Additionally, you can:

  • View the information at an earlier point in time
  • Filter against a particular device, interface, address or VRF assignment
  • Obtain a count of all of the addresses

Each of these provides information for troubleshooting potential configuration and communication issues at the layer 3 level.

View IP Neighbor Information for All Devices

You can view neighbor information for all devices running IPv4 or IPv6 using the netq show ip/ipv6 neighbors command.

This example shows all neighbors for devices running IPv4.

cumulus@switch:~$ netq show ip neighbors
Matching neighbor records:

Filter IP Neighbor Information

You can filter the list of IP neighbor information to show only neighbors for a particular device, interface, address or VRF assignment.

This example shows the IPv6 neighbors for leaf02 switch.

View IP Routes Information

You can view the IPv4 and IPv6 routes for all of your devices, including the IP address (with or without mask), the destination (by hostname) of the route, next hops available, VRF assignment, and whether a host is the owner of the route or MAC address. Additionally, you can:

  • View the information at an earlier point in time
  • Filter against a particular address or VRF assignment
  • Obtain a count of all of the routes

Each of these provides information for troubleshooting potential configuration and communication issues at the layer 3 level.

View IP Routes for a Given Device at a Prior Time

As with most NetQ CLI commands, you can view a characteristic for a time in the past. The same is true with IP routes.

This example show the IPv4 routes for spine01 switch about 24 hours ago.

View the Number of IP Routes

You can view the total number of IP routes on all devices or for those on a particular device.

This example shows the total number of IPv4 and IPv6 routes for all devices on a the leaf01 switch.

cumulus@switch:~$ netq leaf01 show ip routes count
Count of matching routes records: 27
    
cumulus@switch:~$ netq leaf01 show ipv6 routes count
Count of matching routes records: 3

View the History of an IP Address

It is useful when debugging to be able to see when the IP address configuration changed for an interface. The netq show address-history command makes this information available. It enables you to see:

  • each change that was made chronologically
  • changes made between two points in time, using the between option
  • only the difference between to points in time using the diff option
  • to order the output by selected output fields using the listby option
  • each change that was made for the IP address on a particular interface, using the ifname option

And as with many NetQ commands, the default time range used is now to one hour ago. You can view the output in JSON format as well.

The syntax of the command is:

netq [<hostname>] show address-history <text-prefix> [ifname <text-ifname>] [vrf <text-vrf>] [diff] [between <text-time> and <text-endtime>] [listby <text-list-by>] [json]

When entering a time value, you must include a numeric value and the unit of measure:

  • w: week(s)
  • d: day(s)
  • h: hour(s)
  • m: minute(s)
  • s: second(s)
  • now

For the between option, the start (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.

This example shows how to view a full chronology of changes for an IP address. If a caret (^) notation appeared, it would indicate that there was no change in this value from the row above.

cumulus@switch:~$ netq show address-history 10.1.10.2/24
