Cisco Cisco TelePresence Video Communication Server Expressway 관리 매뉴얼
Basic Configuration Is Done
■
Each peer has a different system name.
■
All peers have the same set of option keys installed:
—
The number of call license keys may be different on different peers; all other license keys must be identical
on each peer.
on each peer.
—
The VCS must be restarted after installing some option keys in order to fully activate them.
■
H.323 mode is enabled on each peer (Configuration > Protocols > H.323, and for H.323 mode select On).
The cluster uses H.323 signaling between peers to determine the best route for calls, even if all endpoints are
SIP endpoints.
SIP endpoints.
DNS Configuration is Done
■
The DNS servers used by the VCS peers must support both forward and reverse DNS lookups of Cisco TMS
and all VCS peer addresses; the DNS servers must also provide address lookup for any other DNS functionality
required, such as:
and all VCS peer addresses; the DNS servers must also provide address lookup for any other DNS functionality
required, such as:
—
NTP servers or the external manager if they configured using DNS names
—
Microsoft Lync Server FQDN lookup
—
LDAP server forward and reverse lookup (reverse lookups are frequently provided through PTR records)
Note:
DNS server configuration does not replicate and you must configure the DNS server address on each
peer.
■
A DNS SRV record is available for the cluster which contains A or AAAA records for each peer of the cluster.
This configuration is advised for video interoperability and business to business (B2B) video calling, but is not
required for Mobile and Remote Access.

(For MRA) Create a

(For B2B only) The VCS Expressway cluster has a DNS SRV record that defines all cluster peers
TMS Has Been Configured (if necessary)
■
Cisco TMS, if used, is running version 13.2 or later (12.6 or later is permitted if you are not using Cisco TMS for
provisioning or FindMe).

Next Steps
To create your cluster you must first configure a primary peer and then add the other peers into the cluster one at a
time.

We recommend that you backup your VCS data before setting up a cluster.
Maintaining a Cluster
The Clustering page (System > Clustering) lists the IP addresses of all the peers in the cluster, to which this VCS
belongs, and identifies the primary peer.
