High volume of transmit discards being report to orion. This information does not match what is found on the switch.
No idea why such an alarming rate is being recorded.
Is there any valid explanation why this is being reported?
You need to double-check your switch. I don't know exact command, but I have never came across with discards or errors that were reported incorrectly. Just double check reporting within your switch. Maybe paste it here as well
When you say double check the switch.
What is it that needs to be checked on the switch?
If there is a command that can be issued on the switch what would it be?
Any chance the switch is a Cisco 3750 model? A bug exists in the 3750 series IOS. If this is what you are experiencing, check out this post.
hi book
in many time a switch will discards frames because of miss config of vlan or access list.
run below command on your switch:
show interfaces counters errors
all are 3750 except for one 2960
I found the majority of my original Top 10 Errors & Discards was the result of operator error when configuring trunked ports between two switches or routers.
If you connect two Cisco switches via a trunked port, every VLAN added to the interface on one switch must also be added to the interface on the other switch. If one switch sends L2 broadcast out the trunked port on VLAN X, then VLAN X must be also configured on the other switch's trunked port. If it's not, the other switch will discard that traffic, thus increasing your Discards.
This also pertains to connecting a VSS pair to a switch via a two-port port-channel--all switches' connecting port-channels must contain identical VLAN's in their trunking configuration.
And don't miss that Cisco Gotcha of assigning a VLAN to a trunk port but not actually creating the VLAN on the switch. IMHO, IOS really drops the ball there---it should bark at you if you do this, saying "That VLAN has not been created on this switch, and therefore cannot be assigned to ports."

Hi,
We seem to have a similar issue on our Cisco ASR9ks.
The commands mentioned about does not work on the 9Ks.
I am looking for a definition of how the errors and discards are being measured. I assume if it’s not the total from the router, it’s over some pre-determined time frame?
