12.3 Other VNC-Related Commands

Note: VNC-Related configuration can be obtained via the show running-configuration command when in enable mode.

The following commands are used to clear and display Virtual Network Control related information:

— COMMAND: clear vnc counters

Reset the counter values stored by the NVA. Counter values can be seen using the show vnc commands listed above. This command is only available in enable mode.

— Command: show vnc summary

Print counter values and other general information about the NVA. Counter values can be reset using the clear vnc counters command listed below.

— Command: show vnc nves
— Command: show vnc nves vn|un address

Display the NVA's current clients. Specifying address limits the output to the NVEs whose addresses match address. The time since the NVA last communicated with the NVE, per-NVE summary counters and each NVE's addresses will be displayed.

— Command: show vnc queries
— Command: show vnc queries prefix

Display active Query information. Queries remain valid for the default Response Lifetime (see VNC Defaults Configuration) or NVE-group Response Lifetime (see VNC NVE Group Configuration). Specifying prefix limits the output to Query Targets that fall within prefix.

Query information is provided for each querying NVE, and includes the Query Target and the time remaining before the information is removed.

— Command: show vnc registrations [all|local|remote|holddown|imported]
— Command: show vnc registrations [all|local|remote|holddown|imported] prefix

Display local, remote, holddown, and/or imported registration information. Local registrations are routes received via RFP, which are present in the NVA Registrations Cache. Remote registrations are routes received via BGP (VPN SAFIs), which are present in the NVE-group import tables. Holddown registrations are local and remote routes that have been withdrawn but whose holddown timeouts have not yet elapsed. Imported information represents routes that are imported into NVA and are made available to querying NVEs. Depending on configuration, imported routes may also be advertised via BGP. Specifying prefix limits the output to the registered prefixes that fall within prefix.

Registration information includes the registered prefix, the registering NVE addresses, the registered administrative cost, the registration lifetime and the time since the information was registered or, in the case of Holddown registrations, the amount of time remaining before the information is removed.

— Command: show vnc responses [active|removed]
— Command: show vnc responses [active|removed] prefix

Display all, active and/or removed response information which are present in the NVA Responses Cache. Responses remain valid for the default Response Lifetime (see VNC Defaults Configuration) or NVE-group Response Lifetime (see VNC NVE Group Configuration.) When Removal Responses are enabled (see General VNC Configuration), such responses are listed for the Response Lifetime. Specifying prefix limits the output to the addresses that fall within prefix.

Response information is provided for each querying NVE, and includes the response prefix, the prefix-associated registering NVE addresses, the administrative cost, the provided response lifetime and the time remaining before the information is to be removed or will become inactive.

— Command: show memory vnc

Print the number of memory items allocated by the NVA.
