Check network connectivity to the Cisco
WebEx Data Center, using the traceroute
command from the Cisco WebEx SPA
console as shown in the following example:
traceroute wma.webex.com
traceroute to globalwatch.webex.com

Check network connectivity from the
clients that will be joining the meeting
being hosted on the Cisco WebEx Node
SPA. Use the ping command from the
Cisco WebEx SPA console as shown in the
following example, where 172.16.144.153
is address of the client:
ping 172.16.144.153

The Cisco WebEx Node SPA might not activate properly if network access between the Cisco ASR Series
1000 Aggregation Services Router and certain Cisco WebEx servers is blocked, such as the Cisco WebEx
Data Center SSL Gateway or Cisco WebEx Node Management server. Be sure to verify connectivity to
these servers from the Cisco ASR 1000 Series Router.
