SRND for Cisco IPICS Release 2.0(1)
OL-12456-01
Chapter 7 High Latency and Low Bandwidth Interconnection
Performing Additional Configurations on the Cisco IPICS Server
• Jitter buffer—Enables support for up to 250 ms of maximum jitter on the network (to support burst
latency).
• Link outages—Provides support for temporary link outages so that if the connection from the PMC
is interrupted, the connection automatically continues when it becomes available again. (The PMC
user is not informed of the outage.)
• Bandwidth—Supports 64 kbps bandwidth per channel configured over an M1:U12:M2 connection
trunk.
Caveat
The first time that the PMC logs in to the server, an error message displays to inform the user that the
channels are being disabled. This error occurs because of the time delay to connect. To recover from this
error, click OK. After the server completes its tasks, the channels will display on the PMC (this timing
will vary based on latency).
Performing Additional Configurations on the Cisco IPICS Server
The following additional configurations are required when you use the central site server or the remote
locations deployment solution:
• Updating the RMS Configuration, page 7-5
• Adjusting ARP Commands, page 7-6
• Disabling the RMS Comparator, page 7-6
• Merging the Configuration, page 7-6
• Disabling the PMC Upload Activity Log Frequency, page 7-7
Updating the RMS Configuration
When you use the central site or the remote locations deployment solution, you must update every RMS
that is configured with Cisco IPICS and that is used over a high latency, low bandwidth connection. This
configuration update modifies the maximum TCP outgoing queue on a per-connection basis.
To modify the maximum TCP outgoing queue, perform the following procedure on each RMS:
Procedure
Step 1 Enter global configuration mode by entering the following command:
Router# configure terminal
Step 2 To set the maximum TCP outgoing queue to 100000 packets, enter the following command:
Router(config)# ip tcp queuemax 100000
Step 3 To save your configuration, enter the following command:
Router(config)# write mem
Step 4 To exit the router configuration mode, enter the following command:
Router# exit
