Directory Gatekeeper Group Attributes

You can view the general attributes of a selected directory gatekeeper group (DGKGrp) from the Design View or the Baseline View.

  1. Expand the dial plan tree to view all components.

  2. Select a directory gatekeeper group. The attributes tab is displayed.

Note: You can only add a zone circuit to a directory gatekeeper group if the CSR route type is set to trunk-label or carrier AND the VRC feature set is dp1.1 or later.

The following table describes the attributes of a directory gatekeeper group.

Note: Enhanced functionality attributes can only be viewed and edited if the VRC feature set for this directory gatekeeper group is set to dp1.1 or later.

General Attributes

Description

Name

The name of the DGKGrp. Maximum value is 64 characters.

Cluster Name

The local cluster name assigned by this DGKGrp, if it is configured as clustered. Maximum value is 64 characters. If set, the local cluster name must be unique with respect to all unmanaged zone names, zone alias names, DGK local zone names, and cluster names of other DGKGrps.

RAS Port

The registration, admission, and status signaling port. The range is 1 to 65535. The default is 1719.

Type

The type of redundancy system used for this DGKGrp. The default is none.

  • None - This DGKGrp contains only one DGK and it is the primary DGK.

  • HSRP - Hot Standby Router Protocol. This DGKGrp contains two DGKs; one is primary and one is backup.

  • Overlap - This DGKGrp contains two DGKs; one is primary and one is overlap.

  • Both - Both HSRP and Overlap. This DGKGrp contains three DGKs; one is primary, one is backup, and one is overlap.

  • Cluster - This DGKGrp contains at least two DGKs; one is primary and the second (or all remaining DGKs) must be cluster.

Feature Set

The VRC feature set supported by this DGKGrp.  The default is dp1.0.

Timeout

The timer server timeout (100-ms units). The default is none. The range is 1 to 50.

IRR Timer

Set the IRR reporting interval which it sets on the gateway upon the gateway’s registration. This value can only be set if the VRC feature set is dp1.1 or later. The range is 1 to 60.

Server Registration Port

Configure a port for the gatekeeper to communicate with a Gatekeeper Transaction Message Protocol (GKTMP) server. The range is 1 to 65535.

Server Flow Enabled

Check this box if you want to enable flow control from the VRC server to the network device. The server flow control monitors the average response time from the server to the GKTMP.

Server Flow High

Can only be set if server flow is enabled. The onset percentage of the timeout value used to mark the server as usable or unusable. The range is 1 to 100. The default is 80.

Server Flow Low

Can only be set if server flow is enabled. The abatement percentage of the timeout value used to mark the server as usable or unusable. The range is 1 to 100. The default is 50.

Max Queue Length

Can only be set if server flow is enabled. The threshold for the length of the outbound queue on the gatekeeper. The TCP socket between the gatekeeper and GKTMP server queues messages if it has too many to transmit. If the count of outbound queue length on the server reaches this value, the server is marked unusable. The range is 1 to 2000. The default is 50.

Enhanced Functionality

Description

Server Retry Timer

Specifies the interval (in seconds) to wait between the detection of a server failure and the next attempt to connect to the failed server. This value can only be set if the VRC feature set is dp1.1 or later. The range is 1 to 300.

Disable IRQ Global Request

Disables global requests or call reference values (CRVs) set to zero for newly registering end-points. This value can only be set if the VRC feature set is dp1.1 or later.

LRQ Reject Unknown Circuit

Enables DGK rejection of LRQ messages that contain unknown destination carrier IDs descriptions. This value can only be set if the VRC feature set is dp1.1 AND the CSR route type is carrier or trunk-label.

LRQ/ LRJ Immediate-Advance

Enables the gatekeeper to immediately send a sequential location request (LRQ) to the next zone after it receives a location reject (LRJ) from a GK in the current zone. The default is not enabled. We recommend that you set this parameter if the VRC feature set for this DGKGrp is dp1.1 or later.

LRQ Reject Resource Low

If set, the gatekeeper rejects the interzone call if all gateways in that zone are marked as almost-out-of-resources.

LRQ Receive Password

The LRQ password that the directory gatekeeper assigns to the zones. Set this password to specify an  internal regional password for directory gatekeeper communication. If it is not set, the default regional password is used. This parameter can only be set if the parent managed region role is set to regular and that region has the default LRQ password set.

IZCT Password

Enables generation of the interzone ClearToken (IZCT) password. The range is 6 to 8 alphanumeric characters. You can only set this parameter if the VRC feature set is dp1.1 or later.

LRQ/ARQ Handling

Description

LRQ Reject Unknown

Rejects LRQ messages for unknown zone prefixes.

LRQ Forwarding

Forwards E.164 Location Request (LRQ) messages to remote gatekeepers managing that zone prefix.

  • Yes, the default, indicates that LRQ forwarding is enabled.

  • No indicates not enabled.

Note: VRC does not support simultaneous LRQs being sent on a gatekeeper for a specific zone prefix (LRQ blast), when multiple gatekeepers have the same prefix.

LRQ Delay

Time interval between successive LRQ messages (100-ms units). The range is 1 to 10.

LRQ Window

Defines the time window (in seconds) during which the gatekeeper collects responses to one or more outstanding LRQs. The range is 1 to 15.

Validation State

Indicates whether the Cisco VRC server can contact the element during the Validation process. An element is put in the unknown state when it is first activated.

Details

An optional text string that gives more details about the status of the element. Maximum value is 255 characters.
