Hi Aaron, What is the JUNOS version on this router?
RDP is a Reliable Delivery Protocol. Its an internal TCP-like protocol used between RE and PFE (CFEB board in this case) to communicate with each and exchange information such as route, stats, interface status etc. This communication happens over a socket which connects RE and PFE. Periodic keepalives are exchanged by RE and PFE to check the health of this connection. If you are seeing RDP keepalives timeouts and a subsequent CFEB resets, you should start with checking for the following things. - is RE CPU running high? (show chassis routing-engine and show system processes extensive) - is CFEB CPU running high? (show chassis cfeb) - is CFEB running low on heap/buffer memory? (show chassis cfeb) - is RE running low on system buffers? ("show system virtual-memory" and "show system buffers") - Any type of DDoS attack (ARP storm for example) targeted to the router interfaces sending too many packets to RE. Do you have a loopback filter configured? - If sampling is enabled, any high rate of sampling? Sudden increase in traffic volume may cause more than normal data to be sampled. - investigate possible configuration and routing policy changes in your network that would cause this router to attract more traffic than it earlier did before the problem surfaced. In Addition gather these commands outputs as well (take at least 2-3 snapshots and 5 mins interval). - show pfe statistics traffic - show pfe statistics notification - show pfe statistics discard - show pfe statistics error >From CFEB shell (to log into CFEB, enter shell as root and do "vty cfeb0" - show packet - show packet statistics - show ttp statistics - show heap 0 - show heap 1 - show route summary - show syslog messages - show syslog info - show nvram Gather all the information and provide this data to the JTAC case owner.
