In SV5.0 sp2 Rev C RNRP(2.26) not showing any RNRP messages so system is down due to this
Is there any TC or Fixes for earlier versions of RNRP 2.26 since here in one of our system not showing any RNRP messages on RNRP monitor icon but on pinging each node its pinging and checked service also in started mode
In 5.0 SP2 RevD was much more stable version and RevE was the last Revision released on 5.02 Track.
Also in 5.0 SP2, have you verified that in ..etc\Hosts file entries are present for all 800xA nodes as we need to create manually in 5.0 800xA System Version.
Download and install Wireshark (www.wireshark.org)
Start capture on the client server network using capture filter "udp port 2423".
If you do not see any incoming telegrams from neighbouring RNRP nodes some switch is probably blocking RNRP's multicast traffic.
Cisco and Westermo switches have IGMP enabled from factory default and need to be adjusted (disable IGMP). On Cisco you often need to use the proprietary Cisco Network Assistant tool since they have opted out the IGMP setting from the built-in web server.
Firewall (if used...) must not block RNRP traffic; disable or "drill hole" for "udp 2423".
