Can anyone advise on the queueing behaviour on a 6807 Sup6T
This is the current output from sh interface queueing
My understanding is that currently gi1/5/45 is trusting DSCP (Default Behaviour) but there is no queueing?
6807_Core1#sh queueing interface gi 1/5/45
Interface GigabitEthernet1/5/45 queueing strategy: Weighted Round-Robin
Port QoS is disabled globally
Queueing on Gi1/5/45: Tx Disabled Rx Disabled
Trust boundary disabled
Trust state: trust DSCP
Trust state in queueing: trust COS
Extend trust state: not trusted [COS = 0]
Default COS is 0
Queueing Mode In Tx direction: mode-cos
Transmit queues [type = 1p3q8t]:
Queue Id Scheduling Num of thresholds
I am transitioning from a 6509 where this was configured on the equivalent port.

Any advice on the transition or a pointer to documentation would help as I am confused on the crossover between 6509 to 6807
Thanks

Hi,
Im facing the same setup and migration tasks.
see this Cisco White paper:
https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-6500-series-switches/white_paper_c11-652042.html
Enable Qos by entering : auto qos default
Any port based qos setting is only required in special use cases like traffic shaping or rate limiting.
Nevertheless I was wondering if the is a default policy applied or not. Like on 3850X plattform with auto qos command....
Additionaly the Qos could be optimized on the Box by using Cisco APIC-EM - EasyQoS App.
Regards,
Holger

Add:
auto qos default
After doing this:
CORE-6807#show queueing interface t1/2/17
Interface TenGigabitEthernet1/2/17 queueing strategy: Weighted Round-Robin
Port QoS is enabled globally
Queueing on Te1/2/17: Tx Enabled Rx Enabled
