Set Up for Cisco Unified Border Element (CUBE)

This document describes the necessary steps and configuration commands needed to setup a CUBE for data collection.

Step 1 - Install SSH Client

Before starting, it is highly recommended to install an SSH client on your server that will be hosting the Vyopta collector.

Step 2 - Open Ports

Open all required ports between the server hosting the collector and the CUBE(s). This may require opening ports on a firewall, or allowing traffic via access control lists within the network.

• The data collector needs to be able to access ISR/CUBE:

  • On TCP port 22 (SSH)

  • On UCP port 161 (SNMP agent)

• The ISR/CUBE needs to be able to send SNMP traps to the Vyopta data collector.

  • On UDP port 162

Step 3 - Configure the ISR/CUBE for SNMP access

• Enable SNMP version 2c in IOS.

snmp-server community vyoptacpm RO
snmp-server enable traps dial
snmp-server host <data collector host IP address> version 2c vyoptacpm

• SSH port 22. Configure a limited IOS service account for Vyopta CPM. NOTE – a different privilege level can be used at customer discretion. The levels below are the minimum requirement.

privilege configure all level 5 logging
privilege exec all level 5 show dial-peer voice summary
privilege exec all level 5 show dial-peer voice
privilege exec level 5 show dial-peer
privilege exec level 5 show

• Create the required service account that has SSH access to ISR/CUBE

username vyopta_svc privilege 5 secret <password>

Step 4 - Enable status tracking on individual dial-peers per router

• For each dial-peer, utilize the below commands to configure Out-of-dialog (OOD) OPTIONS Ping for Specified SIP

dial-peer voice tag voip
voice-class sip options-keepalive {up-interval seconds | down-interval seconds | retry retries}

• Example:

enable
configure terminal
dial-peer voice 200 voip
voice-class sip options-keepalive up-interval 100 down-interval 50 retry 6

(these are the recommended and tested values)

Step 5 - Enable media statistics

• Perform the below globally to enable the tracking of jitter, packet loss, and latency

voice service voip
media statistics

• Example

enable
configure terminal
voice service voip
media statistics
exit

IMPORTANT NOTES:

• For IOS (legacy operating systems) enabling RTCP only provides latency information into debug as per Cisco documentation

• For IOS-XE (recommended operating system) enabling RTCP provides latency information into CDRs and Debug as per Cisco documentation

• RTCP being enabled could cause interference with CUCM configurations on media termination point settings. This may have an impact on DTMF (“press 1 to talk to sales”) functionality. If enabled, you must check to see that all permutations of DTMF are still working as expected.
