The ports that need to be open on a firewall for Operations Manager

Resolution

The port usage differs from one device to another.

This list describes the requirements between different devices:

  • Operations Manager (OM) <_-> IP Phones OM does not interact directly with the IP Phones but with the Cisco CallManager who provides the information to OM. There is nothing needed between OM and IP Phones.

  • OM <_-> Cisco CallManager:
       
    • Internet Control Message Protocol (ICMP) (needed for the discovery)

    • Simple Network Management Protocol (SNMP) (161UDP)

    • Hypertext Transfer Protocol (HTTP) (80TCP)

    • Secure HTTP (HTTPS) (443TCP)
       
  • OM <_-> VG
       
    • ICMP

    • SNMP
       
  • Node-to-Node test This is done through Cisco CallManager, so action is taken during these tests.

  • Client PC <_-> Server
       
    • CiscoWorks HTTP port (1741TCP)

    • HTTPS port (443TCP)
