Interface Errors Discards - SolarWinds THWACK Community The majority of discards will be from VLANs being improperly tagged across ports • Frequent Spanning Tree protocol changes that would typically cause a flood of BPDU’s The device would be sending the BPDU’s informing of the topology change • Auto-negotiation failures at both ends of the interface could lead to a high numbers of discards
Understanding Errors and Discards - Geek Speak - THWACK A typical cause of discards is when the router needs to regain some buffer space In the case of discards, the issue is almost always with the router that's reporting the discards (not witha a next hop device, bad cable, etc) RFC 1213 also documents discard reporting and they're right beside the errors within the IF-MIB
Orion Reported Discards - Forum - Network Performance Monitor (NPM . . . " The following routers experienced more than 50 IP routing discards during the day of 2005-03-28 IP routing discards are the number of routing entries which where chosen to be discarded even though they are valid A possible reason for IP routing discards could be to free buffer space to make room for other routing entries "

Transmit discards in NPM, to what to they correspond, Cisco 2900 series The only problem with the Errors and Discards in Orion is that you do not know what kind of Errors Discards they are until you go onto the device and do some show commands You can still poll individual or specific Errors Discards using Universal Device Pollers(UnDP) Just some food for thought - Parker
High number of discards - Cisco 3850 - Forum - Network Performance . . . If you get burst traffic above 100Mbps outbound on this interface you will get transmit discards (I'm not familiar with these switches, but I'd look at why the interface is not negotiating to a gigabit and then outbound traffic shaping, and seeing if I can increase the transmit buffer depth to reduce the problem) )
Cisco Switch high In Out Errors and Discards are highlighted in red Would you also recommend this if the In Out Errors and Discards are in the millions (See screenshot below) We assume that the In Out Errors and Discards on the switch are given in bits and are interpreted by solarwinds as packets This of course leads to these high spikes, even if they are actually only a few Example 1: 11 9 Mio Transmit
what to check when getting high errors or discards on an interface so if you have quantifiable degregation from discards please share it so i can tell them all where they are wrong or at least have a better approach on them for the next round if the packets are being discarded at the interface the application should never be seeing the packet
