After opening up Solarwinds NPM, I noticed that a few of my interfaces had lots of discards (who knows how long it's been sets the counters were reset)
interface GigabitEthernet1/0/25
description Etherchannel to MamaCass
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
priority-queue out
channel-group 4 mode on
interface GigabitEthernet2/0/25
description Etherchannel to MamaCass
switchport trunk encapsulation dot1q

switchport nonegotiate
priority-queue out
channel-group 4 mode on
interface Port-channel4
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
It looks as if priority-queue was configured outbound on these interfaces, could this be the cause of the transmit discards which are now up to 79,835, I just reset the counters on the interfaces a little while ago.
I'm not the best in the world when it comes to QoS, we do have some VoIP phones, but they are only a specific network, and do not travel outside, since there are used mainly for VoIP training. I do know both interfaces are running the default of FIFO.
