Subject Description SRTP connections remain open after IP address changed The Ethernet Interface does not terminate all open SRTP connections before changing its IP address Once the local IP address has changed any existing open TCP connections are unable to normally terminate This can leave SRTP connections open until their underlying TCP connections time out If quicker recovery of the SRTP connection is needed modify the wkal_idle Advanced User Parameter to reduce the TCP keep alive timer down to the desired maximum time for holding open the broken connection Refer to TCP IP Ethernet for Series 90 30 CPU374 PLUS User s Manual GFK 2382 for details Reduced EGD consumption with large numbers of produced exchanges When large numbers of EGD exchanges are produced at a rapid rate some consumed EGD exchanges may exhibit lower rates of consumption than expected To better balance produced and consumed EGD exchange performance reduce the number or frequency of the produced exchanges configured at this Ethernet Interface Spurious Ethernet Failure error On rare occasions the error Module hardware fault may be reported on the Ethernet daughterboard The corresponding fault in the exception log is Event 1 followed by text Ethernet failure This fault is a nuisance fault and may be ignored Spurious Ethernet fault In rare instances after power cycle the Ethernet Interface may log the following fa
