Gatekeeper Group Attributes

You can view the general attributes of a selected gatekeeper group (GKGrp) in the Design View or the Baseline View.

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

  2. Select a gatekeeper group. The Attributes tab is displayed.

Note: You can only add a zone circuit to a 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 gatekeeper group.

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

General Attributes

Description

Name

Required field. The name of the gatekeeper group. Maximum value is 64 characters.

RAS Port

The Registration, Admission, and Status signaling port. The default is 1719. The range is 1 to 65535.

Type

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

  • None - This GKGrp contains only one GK and it must be the primary GK.

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

  • Cluster - This GKGrp contains two GKs; one is primary and one is secondary. All other remaining GKs must be type cluster.

  • Overlap - This GKGrp contains two GKs; one is primary and one is overlap.

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

Feature Set

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

Timeout

The server timeout for Gatekeeper Transaction Message Protocol (GKTMP) messages. The range is 1 to 50.

Server Registration Port

Configure a port for the GK to communicate with a GKTMP server. The range is 1 to 65535.

Tech. Prefix

Special characters to be included in the called number. Select from the list of predefined tech. prefixes.

Server Flow Enabled

You can only set this parameter if the VRC feature set is dp1.1 or later. 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

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 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.

Enable Server Absent Reject RRQ

Configures the GK to reject new registration calls or calls when the connection to the GKTMP server is down.

Enable Server Absent Reject ARQ

Configures the GK to reject admission requests when the connection to the GKTMP server is down.

LRQ Reject Unknown Circuit

Enables GK 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 or later 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 GKGrp 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.

High Resource Threshold

Sets high call volume thresholds in the GK for monitoring its GW. The range is 1 to 99. This value can only be set if the VRC feature set is dp1.1or later.

If both high resource threshold and low resource threshold are set, the value for high resource threshold must be greater than the value for low resource threshold.

Low Resource Threshold

Sets low call volume thresholds in the GK for monitoring its GW. The range is 1 to 99. This value can only be set if the VRC feature set is dp1.1or later.

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

Reject LRQ messages for unknown zone prefixes.

ARQ Reject Unknown

Reject ARQ 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.

LRQ Receive Password

The LRQ password that the gatekeeper assigns to the zones. Set this password to specify an  internal regional password for 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.

LRQ Hop-Count

The hop-count configuration for LRQ forwarding on gatekeepers in this gatekeeper group. You can only set this parameter if the VRC feature set is dp1.1 or later. The range is 1-10.

Security

Description

Security Level

The security level. Choose from registration or all. The default is no security level.

Security Type

Used to enable authentication and authorization on a gatekeeper. Choose from any, h323id, or e164. The default is no security type.

Security Password

The default password that the gatekeeper associates with endpoints when authenticating them with an authentication server. Maximum value is 20 characters.

Separator

The character that endpoints use to separate the H.323-ID from the piggybacked password in the registration. The character is null if H.323 is not used. Value must be a single character.

Resource Management

Description

Load Balance

Specifies whether this gatekeeper group is configured for load sharing between the gatekeepers.

Max. Endpoints

Maximum number of endpoints. The range is 0 to 2147483647.

Max. Calls

Maximum number of calls. The range is 0 to 2147483647.

Max. CPU

Maximum percentage of CPU utilization. The range is 10 to 90.

Max. Memory

Maximum percentage of memory used. The range is 10 to 98.

Bandwidth Allocation

Description

Inter-Zone Bandwidth

Specifies the total amount of bandwidth for H.323 traffic from the zone to any other zone. The range is 1 to 10,000,000.

Total Bandwidth

Specifies the total amount of bandwidth for H.323 traffic allowed in the zone. The range is 1 to 10,000,000.

Remote Bandwidth

Specifies the total bandwidth for H.323 traffic between this gatekeeper and any other gatekeeper. The range is 1 to 10,000,000.

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.
