I have an problem with two servers that are trying to do linkloop to each other and fails. Both are connected to the same switch Catalyst 6509 on the same module X6748-GE-TX. I checked the interfaces are found overrun packets and input queue drops. When I checked detail statistics I found that I see qos0InLost packets. Moreover I see that the input queue drops come from RP (see attachment)
Could You tell me which packets are examine by RP and what might be causing this drops?
Thx for an replay. I don't think it is a switch performance problem, I would rather think that the server is using some type of packet that can't be switched by route processor. The ports are on the same switch\module 8 and it is access-layer switch (no routing defined).
Also please take a look at server errors in attachment.
You are correct on stating the switch performance is not an issue here. I'm not familiar with the procedure you are trying to undertake at the servers but perhaps the RP does not understand the 'linkloop' mechanism between the 2 servers.
The Route Processor (RP) will take care of packets not identified by the Switch Processor (SP).
When you send a packet, it first goes to the Switch Processor (SP) and the SP checks if the destination is on the mac-address-table. If it isn't will be send to the Route Processor (RP) as a last resort.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
