Device Management

Column	Description
Avg Bit Rate (kbps)	Average bit rate of the active calls.
	Note: Bit rate is not the same as bandwidth. Since the bit rate applies in both
	directions and there is overhead, the actual bandwidth consumed is about 2.5
	times the bit rate.
Packet Loss %	Average packet loss percentage of the active calls.
Avg Jitter (msec)	Average jitter rate of the active calls.
Avg Delay (msec)	Average delay rate of the active calls.
Territory	Territory to which the site belongs.
Cluster	Cluster responsible for the territory to which the site belongs.

External Gatekeeper

On the External Gatekeeper page, you can add or remove neighbor gatekeepers. This is a supercluster-wide configuration.

When an enterprise has multiple neighbored gatekeepers, each gatekeeper manages its own H.323 zone. When a call originates in one gatekeeper zone and that zone’s gatekeeper is unable to resolve the dialed address, it forwards the call to the appropriate neighbor gatekeeper(s) for resolution.

But note that a Polycom RealPresence DMA supercluster can manage multiple locations as a single H.323 zone, with the clusters acting as a single virtual gatekeeper. This allows the gatekeeper function to be geographically distributed, but managed centrally. A Polycom RealPresence DMA supercluster may eliminate the need for multiple zones and neighbor gatekeepers.

Note: External Gatekeeper Considerations

When adding a neighbor gatekeeper, you can only specify one IP address. In an IPv4 + IPv6 environment, to add a neighbor gatekeeper that has both an IPv4 and an IPv6 address, do the following:

•Add the neighbor gatekeeper using its IPv4 address.

•Add it a second time using its IPv6 address.

•Add one Resolve to external gatekeeper dial rule (see Add Dial Rule Dialog Box on page 244) that specifies the neighbor gatekeeper’s IPv4 address entry (and no other gatekeepers).

•Add another Resolve to external gatekeeper dial rule that specifies the neighbor gatekeeper’s IPv6 address entry (and no other gatekeepers).

Requests from endpoints with IPv4 addresses will be forwarded to the gatekeeper’s IPv4 address, and requests from endpoints with IPv6 addresses will be forwarded to the gatekeeper’s IPv6 address.

The following table describes the fields in the list.
